Can ExtrusionAnalyzer get Curveloop of Opening?

[InoueKazuyaRo]

Hello, 
I am trying to get profiles of roofs. If a roof has sloped faces, edges of the roof contain ridges and hips.
However, I want just profiles of eaves, rakes, and openings.

I tried ExtrusionAnalyzer to get the profiles. and succeed in getting the profiles of eaves and rakes.

However, failed to get the profiles of openings.

As shown a picture, I can get the profile of only outline.

Can ExtrusionAnalyzer get the profile of only outline? Cannot it get the profile of opening?

Thank you.

I would totally assume that it works.

I would also suggest ensuring that your openings are really empty openings and not blocked by any element geometry such as a window or anything. Ensure they are void.

The extrusion analyser docs say:

Remarks:

An instance of this class is a single-time use class which should be supplied a solid geometry, a plane, and a direction. The utility will calculate a base boundary parallel to the input plane which is the outer boundary of the shadow cast by

the solid onto the input plane and along the extrusion direction.

After the extrusion has been calculated, the class permits a second step analysis to identify all faces from the original geometry which do not align with the faces of the calculated extrusion.

This utility works best for geometry which are at least somewhat "extrusion-like", for example, the geometry of a wall which may or may not be affected by end joins, floor joins, roof joins, openings cut by windows and doors, or other modifications.
