3D Model Tree panel

3D Model Tree panel toolbar

The 3D Model Tree panel toolbar contains many tools for interacting with 3D content.

3D Model Tree menu:

Show All Parts : Makes visible any part which has been hidden and the sets the transparency as defined in the PDF.
Reset All Parts : Resets all parts to their original location. Parts can be transformed (moved and rotated) to other locations. The Reset All Parts command quickly resets the parts in the model back to their default location; it does not change the visibility of parts.
Fit Model: Resizes the model within the 3D Model window to maximize its size relative to the viewing area.
Set Selection Colors: Opens the 3D Model Selection Colors dialog , which enables setting a selected part color and bounding box color, as well as toggling bounding box visibility.
Markup Indicators: Toggles whether to show the Markup Indicators.
Autohide selection occlusions: When enabled, Revu automatically hides parts of a 3D model that would obscure the user's view of a selected part. Default state is set in 3D Rendering Preferences.
Fit part on selection: When enabled, selecting a part of a 3D model on the 3D Model Tree that is not currently visible in the workspace causes Revu to automatically adjust the view to be on that part. Default state is set in 3D Rendering Preferences.
Fit to Window: Fits the PDF is the main workspace , maximizing space for the 3D Model.
Columns menu: Selects which columns are shown in the 3D Model Tree list.
Summary: Exports 3D model data to a CSV file.

Filter menu: Selecting Filter toggles column filters on and off. Select Clear Filters from the menu to clear previously applied filters.

Search: Filters the 3D Model Tree list based on the text entered in the field. Select X in the field to clear the search term.

Default View: Restores view of 3D model to the default view.

Current View: Shows the current view.

Play menu: Select an animation cycle from the menu or select the icon to play the selected animation cycle.

Mouse Interaction menu: Determines the mouse behavior when interacting with the 3D model. The options are Rotate, Spin, Pan, Zoom, and Camera. The menu icon shows the currently selected mode.

Rotate: Moves the camera around the model.

Spin: Rotates the model around a point that is specified in the model. In most cases, Rotate and Spin have very similar behavior. However, Spin may prove more useful on models that have no defined tilt.

Pan: Moves the model up/down and left/right in the 3D Model window.

Zoom: Moves the viewpoint in or out to increase the relative size of the model.

Camera: Rotates the viewpoint from the position of the camera for an effect similar to tilting one's head up or down, or rotating it left or right.

Select: Select parts so they can be moved, rotated, copied or deleted.

/ Switch to Perspective/Orthogonal: Switches between Orthogonal and Perspective views. The Perspective view takes 3D viewing effects such as foreshortening into consideration, similar to real-world viewing scenarios. Objects closer to the camera view appear larger than objects further away. The orthogonal view keeps the relative size of the objects the same regardless of distance from the viewing (camera) position. The menu icon shows the currently selected mode.

Render Mode menu: Selects the render mode, controlling the visible display of the 3D model elements.

Lighting menu: Controls the lighting style used to render the model.

Background Color menu: Controls the color of the background of the 3D Model window.

Cross Section menu: Shows or hides the cross section plane or section box or aligns the camera perpendicular to the cutting plane. See Cross Sections and Section Boxes for more information about using these tools.

Transform: Allows you to manipulate selected parts in a 3D model. Selected parts can be moved, rotated, copied and deleted.

3D Model Tree

The 3D Model Tree shows a list of the components in a 3D model. The tree allows selecting parts and selectively showing and hiding individual or multiple components of the 3D model. Selecting or clearing the corresponding box in the Visible column will hide or show a single part. Doing this for a parent object will toggle the display of the parent and all the child parts.

Additionally, there are many options available using the context menu by right-clicking one or more objects in the 3D Model Tree, for example:

To show all parts in a model, right-click in either the 3D Model window or the 3D Model Tree and select Show All Parts.
To reset all parts to their default location, select Reset All Parts from the 3D Model Tree menu. To reset a specific part, right-click in either the 3D Model window or the 3D Model Tree and select Reset Selected Part.

This will restore the part to its original location after it has been transformed.
To zoom the view to maximize a part's size, in either the 3D Model window or the 3D Model Tree, right-click a part and select Zoom to Part.
To center the display on a part and to make the model rotate around the center point of that part, select the part in the 3D Model window or 3D Model Tree, right-click on the part and select Center Part.

Zoom Part and Center Part both work when a single or multiple parts are selected.

3D View Properties

The settings for a 3D view are defined in the 3D View Properties dialog. Access it by selecting Manage Views from the Current View menu on the 3D Model Tree panel toolbar.

Views list: Shows the views defined for the 3D PDF. Use the controls to the left to rearrange their order or add and delete views.

View Name: Defines the name that will appear in the Views section.

Camera Properties: Defines the projection mode, Orthogonal or Perspective.

Background: When selected, includes and defines the background color. Select the color box to choose a color.

Lighting: When selected, includes and defines the lighting style. Select a lighting style from the dropdown list.

Render Mode: When selected, includes and defines the render mode. Select a render mode from the dropdown list.

Node Visibility: Determines whether or not the current visibility status from the 3D Model Tree section is carried into the view.

Cross Section Information: Determines whether or not the current clipping plane information is carried into the view.

Show and hide parts selectively

Parts may be grouped together to form assemblies, or functional groupings, of 3D elements. A graphical example of this relation is described in the following diagram.

To set the visibility of an individual part or assembly, do one of the following:

Select or clear the corresponding box in the Visible column on the 3D Model Tree panel.
Right-click the part and select Hide or Show.

Examples

Here are a few examples of operations that can be performed using the 3D Model Tree.

Select just one component of an assembly:

Select the triangle to the left of the assembly to show its components.
Select the component in the list. The corresponding part in the 3D model will be highlighted.

Make just one component of an assembly visible:

Select the plus to the left of the assembly to show its components.
Right-click the desired component and select Isolate. Only the selected part will be shown in the 3D model.
If necessary, right-click the part again and select Zoom to Part.

Show the assembly a part is contained in:

Select the plus to the left of the assembly to show its components.
Right-click the desired component and select Isolate Part. Only the selected part's assembly will be shown in the 3D model.

Select components of an assembly and change their collective visibility settings:

Select the plus to the left of the assembly to show its components.
Hold down the CTRL key and select the desired parts.
Right-click any of the selected parts to change visibility settings for all selected parts.
