Creating Collision Geometry

Collision geometry can be created to represent the geometry of a component for collision detection purposes. Collision geometry can be significantly simpler than the component's actual geometry, and therefore, it can significantly enhance the speed of collision calculation.

To create a collision geometry:

  1. Select the root node of a component from the Component Graph panel.
  2. On the MODELING tab, in the Geometry group, click the Tools arrow, and then under Collision Geometry, select Create Collision Geometry.

  3. Define the parameters for your collision geometry in the Create Collision Geometry panel:

    • Links to simplify: Select the component links for which collision geometry will be generated.

    • Method:

      • Convex hulls: Generates one or more convex shapes that closely wrap the original geometry.

      • Blocks: Approximates the component using simple rectangular boxes.

    • Quality: Defines the level of detail retained from the original component geometry during simplification.

    • Precision mode: Increases the accuracy of the generated collision geometries by using more detailed calculations during the simplification process.

    • Max geometry set count: defines the maximum number of geometry sets that can be created per link when simplifying a component’s original geometry into collision geometry. A higher count creates more detailed collision geometry (closer to the original shape), while a lower count produces simpler shapes for faster collision calculations
