How to check Interference between two Faces API Solidworks

3D Design Volume Model
1

Hi

I am working on 3D Model in Solidworks. I would like to know which function I have to use to check interference between two faces (from different component) in particular? If anyone has a macro, I am really interested.

Thank you for yours answers :)

Hello,

SolidWorks have a function for check Interferences in assembly : http://help.solidworks.com/2015/english/solidworks/sldworks/hidd_dve_interference.htm

Do you know this function ?

Hello,

Thank you for your answer. Yes I know this function, but I would like to check Interference automatically with a macro on Visual Basic For Application.

In this case, you can read this example : http://help.solidworks.com/2015/english/api/sldworksapi/run_interference_detection_example_vb.htm

And also results for the search in SolidWorks APi Web Help : http://help.solidworks.com/SearchEx.aspx?query=Interference&version=2015&lang=english&prod=api

Thank YouRemrem for the links. I had already seen the links. The first shows the interferences in the global assembly. What I want is the interference between two faces from different parts like Face1 of Body1 interfere with Face1 of Body2 for example. I searched on internet, I am not sure it's possible for face.

I try a macro but It doesn't work
