The Clash Detection calculates a list of the clashing parts in an assembly. You can also compute additional parameters like penetration depth and select various types of visualizations.

▪Activate the Clash detection function by clicking the button with the same name in the Analyze tab.

▪You can select the following parameters for clash detection in the Tools pane:

a.Selecting the checkbox Compute details will compute the type of contact Contact/Collision and any penetration depth for the collision pair list Node names – Node name. In addition the included points and edges are calculated so that they can be displayed directly for visualization (see bullet point 4.).

b.Contact/collision threshold specifies the penetration depth in the model unit, from which collision pairs are no longer classified as Contact. This tolerance value can be used to e.g. balance out any inaccuracies in the tessellation.

c.You can select the parts for which a possible clash is to be examined from the Compute clash for selectin list:

▪Visible parts: All parts will be included that are not ghosted or hidden.

▪Saved selection sets: Computes collisions only for previously saved selection sets.

▪Initiate the clash detection via the Compute button. The computing time will depend on the model size and processing power of your computer. You can continue interacting with 3DViewStation while the process is running. The progress of a current computation of detail information can be viewed via the button [Computing].

▪By selecting a row in the clash list, you can highlight the corresponding pair and specify the type of display in the section Visualization:

▪Show clash by:

▪Selection: The pair is selected.

▪Hide other parts: All parts except the selected pair are hidden.

▪Ghost other parts: All parts except the selected pair are displayed as in ghost mode.

a.Zoom fit: The selected collision pair is zoomed to fit the image.

b.Clash pair transparency: Transparency control for the analysis of clashes in covered areas.
