Selection Set Creation

Mohit Hemnani Jun 27, 2017 3:45 PM

Is it possible to create a selection set of faces in a solid geometry and have its corresponding contacting set of faces be automatically selected in its negative space?

This is possible manually for simple assemblies, but becomes cumbersome when the geometry is complex.

In the example shown below, is a simplified piston head assembly with negative space (in red).

If a selection set of faces is made in the piston.

Is it possible to select corresponding contacting faces in the negative space automatically?

What in means a "negative space" of contact set? Is it a widely used term or just your invention?

  The negative space is supposed to represent the air space between the piston and the head. Our aim here is to find the heat transfer from the combustion space to the piston crown. Hence we need to identify and select the corresponding contacting surfaces.

    If the goal is to automate the selection process the best space to ask is API/Macros section.
