User Representations in Collision Checking

See User Representations for details about the use of User Representations.

If an User Representation has an invalid profile, a warning message is displayed. The profile of the machining operation, not of the user representation, is taken into account.

When the tool is described by a CATProduct, it is defined by several sketch profiles.
You cannot mix cutting and non-cutting profiles.

Rules for collision checking are:

• The lowest profile is always regarded as a cutting profile.
• Next profiles are regarded as cutting profiles, until a SHANK, CLEANING, or HOLDER parameter is found.
• Others profiles are regarded as non-cutting profiles.

If the user representation is modified inside a V5 session, modification will not be recognized and the collision checking will not be automatically re-computed. You must force the computation of the operation using the tool.

Example of scenario to avoid:

Inside the same session:

• tool path is replayed with collision check active on an operation linked to a tool having a user representation => OK
• the user representation is modified => OK
• tool path is replayed again => KO: the collision checking is not automatically re-computed.
