This task illustrates how to make the most of section
viewer capabilities: Accessing the Section Result Window capabilities
Most of the commands described in this task are to be found in the Result tab of the Sectioning Definition dialog box or in the Section result window contextual menu.

Before you beginWhen dealing with CATProducts containing a large amount of sections, for performance gain purposes, read carefully the Customization recommendations (follow the described procedure).
Section Results Window
The Section Results window appears alongside the document window (by default, it is automatically open). It displays a front view of the section, and is by default, locked in a 2D view. Points representing the intersection of the section plane with any wire frame elements are also visible in the Section result window.
When performing multiple sections, you need to
arrange (resizing and positioning) their section result windows
in an appropriate way. From R17 onwards, you can customize the
sectioning result window; Customizing the section result window sizeSelect Tools > Options > Digital Mockup > DMU Sectioning tab. In the Results window settings category, select the required categories of options and click Ok when satisfied.
Customizing the section result window positioning
Note though that if you select the Tile vertically option in Windows Result area (Tools > Options > Digital Mockup > DMU Sectioning tab) the positioning is forced and automatically defined:

Orient the generated section.Flip and Rotate commands are to be found in the contextual menu. Right-click in the Section viewer and:
|
|
|
|
|
Orienting the section using Flip and Rotate commands is not persistent. If you exit the section viewer, any flip and rotate settings are lost. |
Click the Result
tab in the Sectioning Definition dialog box, then select
Grid
under Options to display a 2D grid.
|
|
You can edit the grid step, style and mode using the Edit Grid command. |
|
Select Edit
Grid
to adjust grid parameters: The Edit Grid dialog box appears:
In the above example, the grid mode is absolute and the style is set to
lines.
|
In the absolute mode, grid coordinates are set with respect to the absolute axis system of the document. The grid step is set to the default value of 100. The arrows let you scroll through a discrete set of logarithmically calculated values. You can also enter a grid step manually. Units are current units set using Tools > Options (Units tab under General > Parameters and Measure). |
Scroll through grid width and height and set the grid step to 10 x 10.
Click the Relative mode option button: In the relative mode, the center of the grid is placed on the center of section plane.
Click the Crosses style.
|
Grid parameters are persistent: any changes to default parameters are kept and applied next time you open the viewer or re-edit the section. |
Click Automatic filtering check box to adjust the level of detail of grid display when you zoom in and out.
Right-click the grid then select Coordinates to display the coordinates at selected intersections of grid lines. The Clean All command removes displayed grid coordinates.
Click OK in the Edit Grid dialog box when done.
By default, the Section viewer is locked in a 2D view. De-activating the 2D view lets you:
Work in a 3D view and gives you access to 3D viewing tools
Set the same viewpoint in the Section viewer as in the document window.
Returning to a 2D view snaps the viewpoint to the nearest orthogonal view defined in the Section viewer.
Right-click in the Section viewer and select the 2D Lock command from the contextual menu. The Import Viewpoint command becomes available.
Manipulate the section plane.
|
Right-click in the Section viewer and select the Import Viewpoint command from the contextual menu. The viewpoint in the Section viewer is set to that of the document window.
|
Continue manipulating the section plane.
|
Return to a locked 2D view.
The viewpoint in the Section viewer snaps to the nearest orthogonal viewpoint in this viewer and not to the viewpoint defined by the local axis system of the plane in the document window. |
|
You can also save sectioning results in a variety of different formats using the Export As command in the Result tab of the Sectioning Definition dialog box or the Capture command (Tools > Image > Capture). |
Click OK in the Sectioning Definition dialog box when done. If you exit the Sectioning command with the Section viewer still active, this window is not closed and filled sections remain visible.
In DMU-P2, You can detect collisions between 2D sections.
To do so, click Clash
Detection
in the Result tab of the Sectioning Definition dialog box.
Clashes detected are highlighted in the Section viewer.
|
Collision detection is dynamic: move the section plane and watch the Section viewer display being updated.
|
Note: Clash detection is not authorized when in the Section Freeze mode.
