Working set

The working set lets you specify which actors participate in the test.

Note: Working set selections are not saved in profiles.


Command Name	Description
Working set	Specifies which actors participate in the test. Check selection - Checks only actors in the current selection, selection set, or hotspot. Selection versus all - Checks actors in the current selection, selection set, or hotspot against all other actors. Selection 1 versus Selection 2 - Checks actors in the current selection, selection set, or hotspot against the actors in another selection.

These options specify the clearance checking scope.

In this illustration, both On visible actors only and Full check are selected.


Command Name	Description
On visible actors only	Tests visible actors only. When cleared, performs tests on all actors.
Full check	Analyzes clashes for all triangles of the selection so that all intersection lines can be calculated. When cleared, clash detection stops as soon as two triangles collide. Note: Full check is time and memory intensive.

Control type lets you specify which test to perform.


Command Name	Description
Control type	Specifies which test to perform: Clash test - Identifies intersections and contacts between selected geometry actors taking into account the difference between CAD models and the geometry. Some displayed intersections might be contacts based on the precision on the models. The value of the precision is the chordal error (see Refinement). Clearance checking - Runs the analysis using the specified minimal distance between actors. The analysis detects pairs of collided actors (closer than the minimal distance). Minimal distance - Calculates the minimal distance between various actors. The analysis identifies the actors in collision and the pair of closest actors in the selection. Precision lets you set the determination step between intersections and contacts. This value is computed according to your model quality settings (see Refinement): a higher quality setting increases precision, a lower one decreases it.

These options are available with the clearance report.


Icon	Command Name	Description
	Compute	Performs the selected test.
	Save Results	Saves results in XML, HTML, Excel, or CSV format.
	Load Results	Loads a previously saved file of clearance results to avoid recalculating.
	View/Hide Result	Displays or hides results.
	Show Selected Result Only with Ghost	Ghosts the selected results.
	Build Collaboration	Creates intersection-line collaborative actors for the selected results. See also Multi-line building.
	Clear All	Clears the clearance checking session.
	Multi-line building	Creates an intersection-line collaborative actor for each intersection between two actors. To create one intersection line with all intersections between actors, clear this option.
	Result Columns	Displays the contacts and intersections. Click a result to see the actors in the scene. Right-click a result and click Fill data to add comments or select a Status ( Undefined, Relevant, or Irrelevant).
