Customizing object properties

All objects in Vivien have properties. Properties are the characteristics or attributes that shape and define objects (for example, dimensions, color, and texture).

Properties that affect color, line weights, shading attributes, are common to all drawn objects. Objects also have properties that are particular to the type of object. When you select an object and display its properties, a tab appears in the properties dialog box for that type of object. When you select multiple objects of different types, tabs appear for each type of object selected.

To edit object properties

1. Select the object(s) that you want to edit.
2. From the Modify menu, choose Object Properties.

Result: The Properties window opens.

Details about the options on the Properties window are described in the following sections.

For information about Library object properties, see “Library object properties”.

General object properties

In Vivien, there are three tabs that appear in the properties dialog box for every object in your drawing. These three tabs are the General, Appearance, and Light Emission tabs.

For 3D solids and surfaces, the Solids and Sidedness tabs also appear in the Properties window.

Objects also have properties that are particular to the type of object selected. A tab appears on the Properties window specific to that object. For details, see “Object-specific properties”.

General tab

Options on the General tab affect the selected object(s) color and line weights.

• Layer list: A list of the layers in your document displays. Click a list item to change the layer the object(s) will be drawn on.
• The layers are listed below the Layer Groups if the Display with Layer Groups checkbox is selected.
• Only the layers are listed if the Display with Layer Groups checkbox is clear.
• Display with Layer Groups: Select this checkbox to display the layers as items organized in Layer Groups. Clear this checkbox to display only the list of layers.
• Collapse All button: Click this button to display only the Layer Groups.
• Expand All button: Click this button to display the Layer Groups and all the Layers.
• Use Layer Color: Select this option to set the object(s) color for drawing views to be the same as the properties of the layer on which the object(s) resides. For more information on layer properties and the coloring objects, see “Layer properties” and “Rules for objects’ colors in Vivien”.
• Clear this checkbox and use the color button to set a specific color for the object(s).
• Line Weight: From the drop-down list, choose the specific line weight for the selected object. The applied line weight is visible in all Wireframe views in all modes. For objects only, you can also choose the default setting, ByLayer, which sets the object’s line weight to be the same as the properties of the layer on which the object resides. The value Default means that the document's line weight setting from the Document Options > Object Settings window is applied to the object or layer. For more information on layer properties, refer to “Layer properties”.
• Uncheck this option and enter a weight in the box below to set a specific line weight for the object(s). The line weight determines how thick the pen should be when printing a copy of the document. The applied line weight is only visible in Print Preview and when printed.
• Not available for Library items.

Hatching

Customizable styles of how the wall is viewed in wireframe view. These setting will not effect how walls are viewed in virtual views.

• Show Hatch Lines: Select this checkbox to display hatch lines on 3D solid objects and surfaces. You can click the drop-down list to select the hatch style or click the New/Edit box to create new hatch styles or edit the hatch styles. Refer to “Hatching”.

Appearance tab

Use this tab to specify the appearance of the different components that make up the currently selected item. Based on the item that you have selected, the options in this tab differ.

You can use this tab to customize library items by adding different materials, colors, and textures to each element of the item. For example, the leaves and planter of the Potted Plant object can have different colors applied to them.

You can also use this tab to rename the individual elements of the currently selected object. This is useful for objects that contain many elements with similar names, like risers.

Note: You can apply textures to venues, surfaces, risers, walls, library items, spheres, cylinders, and cones. You can apply transparency to everything. When customizing the selected element, you can choose between applying a custom color or a custom texture—you cannot choose both. In addition to either color or texture, you can also apply material.

Highlight the element that you want to customize, and then choose one of the following options:

Color/Texture

• Ignore Ambient Light: The selected element(s) will always appear using the color values derived from the Appearance options specified (e.g., texture). While light emission and light from fixtures will further saturate the colors displayed for the selected object, ambient light will never affect this object if this option is enabled. This option is useful when objects (except Screens) are textured with images or video, and these need to appear in their original colors at all times. In renderings, this setting is ignored if light emission is enabled.
• Layer Rendering Color: Select this option to set the object(s) color to the same as the properties of the layer on which the object resides.
• Custom Color: Select this option and then use the color button to set a specific color for the object(s).
• Texture from Library: Select this option to apply a texture from the library to the selected object(s). In the resulting window, navigate to and select the desired texture. You can apply textures to venues, surfaces, risers, walls, library items, spheres, cylinders, and cones. Click the ellipsis button (...) to change the selected texture file.
• Image Source: Select this option to apply to the selected object(s) a texture that you have created and saved in either .bmp, .jpg, .png, or .gif format. To apply the image, you must create a new Image Source. To do so, click New, and then use the Image Manager to create a new Image Source with the image you created.
• Video Source: You can apply a video source or a subsource as a “dynamic texture” to Screen objects or Library objects with the screen element, such as projection screens, TV screens, digital display screens, etc. Select this option to apply a previously created video source or subsource, or click New to create a new video source or subsource directly from this window.
• Use Normal Map: Select this checkbox to apply an Image Source that’s a Normal Map, to create the perception of fragmented surface texture detail and depth, making objects look more realistic.

Click this drop-down box to apply an existing Normal Map image or click New to create a new Normal Map image via the Image Manager.

Note: This drop-down lists all Image Sources that appear in the Image Manager; as such, Image Sources which are Normal Maps should be named appropriately, for easy identification.

• Scale: Select the height or depth of visual effect created by the Normal Map. Click the drop-down box to select the percentage scale value from not visible (0%) to maximum value stored in the imported Normal texture/image (100%).

If you have chosen a texture option, then you can also set the properties of the texture as follows:

• Tile: Select this option if you want to have the texture repeated over the selected element in a continuous series of squares or rectangles, and then type the size of the frame in which you want the texture to appear in the Width and Height boxes. Based on the size that you enter, Vivien calculates how many times the texture is repeated (or tiled) to completely cover the selected element.

Note: When tiling a texture on a sphere, cylinder, or cone, by default it will completely wrap around the object. If you change the tile size, you will scale the texture up or down accordingly. If you revert back to the original tile values, you return to the default view.

• Stretch: To have the texture stretch over the entire element surface, click this option button. Based on the aspect ratio and the rotation angle, Vivien evaluates the surface with all of its edges and stretches the texture so the best fit is used. Note that this option is not applicable when you apply textures to spheres, cylinders, or cones. For these objects, Tile is the only option.
• Keep Aspect Ratio: Select this option to keep the aspect ratio of the original image when it is stretched over the surface of the object you have selected. This option helps avoid distortion of complex textures. If the texture image cannot wrap completely over the entire surface of the object while maintaining its original aspect ratio, then the color that you choose in the Border Color box will be applied evenly around any excess surface area not covered by the texture (much like a picture frame around a picture).
• Border Color: If you have chosen to preserve the texture’s aspect ratio, click this box to choose the color that will be applied evenly around any excess surface area not covered by the texture (much like a picture frame around a picture).
• Normal Map Size Multiplier: If you selected Use Normal Map, specify the number of times the Normal Map is multiplied across the object (element) to which it is applied. Type a value in the Normal Map Size Multiplier box. (Enter a valid number between 0.01 and 100.)

Notes:

• The default value is 1 results in no changes to the Normal Map’s size; values lower than 1 will increase the size of the Normal visual effect, and values higher than 1 will decrease it.
• The Normal Map Size Multiplier operates within the Tile or Stretch Texture Options.
• Texture / Source Tint: This option will allow the color of an object’s texture to be altered from the source color.
• Texture Rotation: If the texture has text or another recognizable image in it, you might need to rotate the image to get it right-side up. Select the rotation angle from this box.

Proceed with the following properties settings:

• Material Properties: Click the ellipsis button (...) to choose a material for the selected elements. Click Default to remove the selected material from the element and return to the default material.

Material

When a material is selected, the properties of the material will vary from one material to the next. The Material Properties section enables these default material settings to be changed. Each property value can be changed on a scale from 0%-100%. An explanation of the value is found on the right side of the property.

• Transparency: This setting controls the proportion of light that passes through the material. 0% being completely opaque, 100% being completely clear.
• Specular Level: This setting controls how prominent other specular effects appear on the material. 0% being no visibility of specular effects, 100% being a maximum visibility of specular effects.
• Specular Gloss: This setting controls the level of gloss a material will project. 0% will project the gloss over a wide area, 100% will concentrate the gloss in a small area.
• Specular Color Source: This setting controls the color of light projected on a material. 0% will show only the color of the light, 100% will show only the color of the material.
• Light Reflection: This setting controls the amount of light that is reflected off the material. 0% having no reflection, 100% being specular.
• Display Reflection in Virtual Views: This setting controls whether true reflections are shown by the object’s material in Virtual Views.

Cast Shadow

The Cast Shadow feature gives you the option to cast shadows and display footprints of objects in Virtual View.

• Cast Shadow: Select this checkbox to display in Virtual View, the footprint/shadow of the selected object. By default, Cast Shadow is enabled for all objects; on the other hand, Cast Shadow is disabled for all hang structures and fixtures by default.

To rename object elements

You can use this procedure to rename object elements that have similar names, giving them a more descriptive name. For example, if you have customized a riser, you could give each side of the riser a distinct name according to its custom properties. This is especially useful for custom objects that you have drawn and are going to save as custom library items. Since you cannot rename individual elements of custom library items, it is best to do so before you save the item.

1. Under Elements, highlight the element that you want to rename. For example, highlight Riser - Back.
2. Click Rename.
3. Type the new, descriptive name for the element.
4. Click OK.
5. Click OK in the Appearance tab to save your changes.

Light Emission tab

Options on the Light Emission tab affect the light emission properties for the selected object(s). Light emission is defined as the ability for objects to glow or emit light and can be used to simulate LEDs, lasers, neon, light boxes, projection screens, glowing furniture, and so on.

Highlight the element that you want to customize, and then choose one of the following options:

Light Emission Glow

In this section, you can enable or disable the Light Emission Glow feature per object or per Element of an object.

Note: Glow must be enabled in the Light Emission section of the Visual Effects tab in the View Options window to show the light emission glow effect from objects in Virtual View.

• Enable: Select this checkbox to display in Virtual View the light emission glow effect from the selected Element of the selected object.

Clear this checkbox to disable the light emission glow effect from the selected object. By default, Light Emission Glow is enabled for all objects except Screens.

Tip: Screen objects have a separate glow option, called Screen Glow, which is enabled globally via the View Options > Simulation tab in Virtual View.

Note: If Light Emission Glow is enabled for a selected Element of an object with multiple Elements (such as Risers, Cylinders, etc.), only the selected Element will show the light emission glow effect in Virtual View.

• Enable Light Emission: Select this checkbox to enable light emission for the object, and then choose the light emitting properties.
• Color: Click the color box to choose the color of the light emission. Note that this color overrides the object's original color, so it is best to choose a similar, if not identical, color.
• Intensity: Select the light-emitting intensity of the selected object. To adjust the brightness of the object as it appears in renderings and Virtual Views, choose a new intensity from this drop-down list.

Sidedness tab

Options on the Sidedness tab affect how the selected object appears in Virtual Views and renderings. Aside from the tents that come with the Vivien library, you cannot change the sidedness of any of the objects that come with Vivien, either library objects or default venues. By default, all objects in the Vivien library except the tents are double-sided, which means that when you rotate them in Virtual Views, all sides display equally and you cannot see through them. Conversely, the default venues that come with Vivien are single sided, which enables you to see “into” the venue when you rotate the image in Virtual Views. (By default, the tents in the library are also single-sided, which means you can see through them in the Virtual View. However, you can change this feature by making the tent double-sided. For details, see “To change an object’s sidedness”.)

You can also change the sidedness of objects that you have drawn in another program and imported into Vivien (i.e.,.dwg, .dxf files or SketchUp files) or objects that you have drawn in Vivien, such as custom venues, surfaces, or custom objects that you have added to the library.

For these objects, you can use this tab to change the sidedness from single to double sided, or vice versa. For example, if you have drawn a venue as double sided, you can select it and change it to single sided so that it behaves in the same manner as the default Vivien venues (i.e., you can see into the venue as you rotate it in Virtual Views). If you prefer to have an outside view of the custom venue, then the double sided option is best as it prevents you from seeing “through” the walls.

Note: You can also use this feature to flip the faces of a custom surface from one direction to the other if you do not like the way the object appears in the Virtual View. For example, if the color or texture of the imported object is facing inward when viewed on the Virtual View tab, click to select the object on either of the drawing tabs. Right-click and choose Object Properties. Click the Sidedness tab. Click Flip Normal, and then click OK.

To change an object’s sidedness

You can use this procedure to change objects from single to double sided and vice versa. You can also flip the faces of a single-sided object so that they are oriented in the opposite direction, either inward or outward.

Note:  Aside from the tents that come with the Vivien library, you cannot change the sidedness of any of the objects that come with Vivien, either library objects or default venues. By default, all other objects in the Vivien library are double-sided, which means that when you rotate them in Virtual Views, all sides display equally (they are not see through). Conversely, the default venues that come with Vivien are single sided, which allows you to see “into” the venue when you rotate them in Virtual Views.

1. Select the object that you want to edit.
2. Right-click on the object, and then select Object Properties.

Tip: At any time, to access an object’s properties, you can click the Object Properties tool on the Modify toolbar.

Result: The Properties window appears.

3. Click the Sidedness tab.
4. Click the appropriate option button, either Double Sided or Single Sided. To leave the single-sided object’s faces oriented in the same direction in which they were drawn, proceed directly to step 6. To change the direction of the faces, see step 5.
5. If you are changing a double-sided object to single sided, and you want to change the direction in which the object’s faces are oriented (either outward or inward), select the Flip Normal checkbox.
6. Click OK.
7. Review your changes in the Virtual View tab and make adjustments as required.

• Double Sided: Select this option to turn the single-sided object into a double-sided object. Note that aside from the tents in the Vivien library, you cannot change Vivien’s default venues from single to double sided.
• Single Sided: Select this option to turn the double-sided object into a single-sided object. For example, if you have created a custom surface/wall/venue and have imported it as a double-sided object into Vivien, you can select it and make it single sided so you can see “into” the venue when you rotate it in Virtual Views.

Note: Aside from the tents in the Vivien library, you cannot change any of Vivien’s other library objects from double to single sided.

• Flip Normal: If you have imported a custom-drawn object or drawn an object in Vivien and you see in the Virtual View that it appears incorrectly (the “faces” showing the texture/color are pointing inward), select this checkbox to flip the faces in the opposite direction, and then look at the object in the Virtual View again.

Object-specific properties

Objects also have properties that are particular to that type of object. For example, light fixtures have unit numbers, but do not have a radius. When you select an object and display its properties, a tab appears in the Properties window box for that type of object. When you select multiple objects of different types, tabs appear for each type of object selected. The following objects are defined here:

• points
• lines
• cones
• spheres
• text labels
• dimensions
• library items
• light fixtures
• projectors

For venues, refer to “Defining the venue”. For circles, arcs, walls, risers, cylinders, spheres, screens and cameras, refer to “Drawing objects”. In these cases the properties dialog offers the same options that were given when the object was initially drawn.

2. Navigate to the desired object.
3. Select the object and then click the Properties tool at the top of the Library Browser.

The Properties button.

or

Hold the ALT key and double-click the object name.

Result: The Properties window for the selected object opens.

Two tabs appear in the properties dialog box for every object in the library: Appearance and Characteristics. Light fixtures also have Options and Projection tabs.

Tips:

• You can open properties dialog boxes for multiple objects at one time. You might want to do this to compare data, such as weight information.
• To view library object properties without opening individual property boxes, browse the library using the shortcut bar. To do this, select the shortcut bar for the type of object you want to view. Right-click in the shortcut bar and choose New Object (for example, New Chair). The Library Selection dialog box opens with a properties pane included.
• You can modify some object properties create the look you want. You can also associate costing information with each object. For details, “Customizing object properties”.

Appearance tab

The Appearance tab displays a Virtual View and an image of the symbol for the library item.

• View Type: Indicates whether the Virtual View of the object is fixed (static) or animated (moving).
• View: Click Plan, Side, or Front to view the object symbol in the different views. The Wireframe view changes depending on the view type that you select.

Event Resources Defaults

Options on the Event Resources Defaults tab are read-only and are set when the object is added to the library.

• Version: Release number of the library object.
• Status: Status of the library object. Beta indicates that the object is completed but not verified. Release indicates that it has been tested and is accurate. A status of Preliminary indicates that the object has minimal functionality.
• Author: The individual or company that constructed the library object.
• Supplier: The company or individual that provides the library object
• Website: The relevant website of the library object.

• Edit Defaults: A menu for editing the selected library item’s Supplier, Website, Cost and Ext. Price characteristics.

For more information on how to manage the properties of event resources, “Managing/Editing resource properties”.

Projector properties

After you use the Projection Wizard to draw a projector on its own or a projector/screen combination, you can use the Properties dialog to change the settings of the projector and screen. If you double-click a projector/screen combination, the following tabs appear:

• Projector
• Drape Kit (only if you have drawn a folding screen)
• Screen Frame
• Screen

While most of the boxes on the Properties tabs are the same as those that appear while you create the projector/screen, a couple of boxes are unique to these tabs, meaning that you can specify certain types of properties only through the Properties tabs, as shown in the procedures that follow.

To hide the projection rays in wireframe view

By default, when you draw a projector, the projection rays are shown in Wireframe views. However, you can use the Projector properties tab to hide them.

1. In the Drawing Wireframe or Drawing Quad tab, click to select the projector, and then right-click and select Object Properties.
2. Click the Projector tab.
3. Clear the Show Projection Rays in Wireframe checkbox.
4. Click OK.

To specify the diameter of the screen’s support frame/tripod

By default, when you draw a projector and screen (or a screen on its own), the diameter of the supporting frame is set to one inch. However, you can change the diameter to any value you like, as shown below.

1. In the Drawing Wireframe or Drawing Quad tab, click to select the projector/screen (or just the screen), and then right-click and select Object Properties.
2. Click the Screen Frame tab.
3. In the Support Diameter box, type the new diameter of the screen’s support frame or tripod.
4. Click OK.
