Part analysis - create/display load transfer surfaces 1

[GaborHun]

I analyse a machine frame in Cosmos. Smaller parts are welded onto the main frame in the frame assy. I'd like to analyse the main beam as a part.
The forces are transfered through welds, and if I open the main beam as a standalone part, the areas where the forces work are obviously not visible, but I can't find a way to define face sections, where the loads are transfered.
Is there any way to create a region in a part, where forces may be applied?
I used to extrude the contacting surface a tiny bit, so I could select it and apply the force to that surface, but it is a barbarian method, I know. Any civilised alternatives are welcome.

You can do it using the 'Split Line' option.

To do so, open the part separately & on the face of the part where you want to make your "patch", create a sketch and draw the shape of the patch as necessary. Then use the Split-Line option (go to Insert > Curve > Split-Line) to create the patch as required (Hence the term split-line, because you are splitting a surface or face or a part with your own "lines")

You can also use the Split-Line option in Assembly mode whereby you can project one component's face or region onto another component, thereby creating the patch necessary on the component.

Oh, and you can apply your force or any boundary conditions on the newly created patch as required

Thanks a million!
