This macro shows you how to use clashes to compute and filter an interference: all conflicts with a given type or with a penetration depth greater than a given value will be declared as irrelevant with a comment. The macro assumes that a CATProduct has been loaded and that some components are selected.
This image shows the selection state before the use of the macro :

CAASpaClashFiltering is launched in CATIA [1]. A previously opened document is needed.
CAASpaClashFiltering.CATScript is located in the CAAScdDmuUseCases module. Execute macro (Windows only).
CAASpaClashFiltering includes four steps:
- Acquiring the filtering value
- Retrieving the clashes collection
- Creation and computation of the clash
- Filtering of the conflicts
Acquiring the filtering value
The dFilterValue value is acquired with a Inputbox.
Retrieving the clashes collection
The cClashes collection (see Clashes
) is the factory to create Clash
object : this collection is retrieved using the GetTechnologicalObject
method, with the string "Clashes", on the root
product of the active document.
Creation and computation of the clash
The oClash object is created using AddFromSel
method on the cClashes collection to take into account all selected
components, modified with the ComputationType
and the InterferenceType
methods to perform the right computation, and then computed with the Compute
method.
Filtering of the conflicts
A loop is done on all the conflicts using Conflicts
on oClash, to get cConflicts collection, Count
to read the number of conflicts and Item
to access each of them, oConflict.
The filtering is done using Type
and Value
methods, on oConflict, to get the results.
If needed, the status and the comment of the conflict are modified with
Status
and Comment
methods.
