Get surface from list surface?

[mr.engineer.aec]

Hi guys,

I have a list surface from element.
I get all surfaces is parallel.
After that, i want to get two surfaces outermost.
What can i do to get them?
I thinked to use Local Coordinate System, but then i don’t script to continue.

Many thanks.

Hi @mr.engineer.aec,

According to the picture you shared.

• filtering by parallel surfaces,
• Turn surface to curve,
• Filter by length.

Hi @mr.engineer.aec,

You could use the properties of the plane and in particular sort them by their origin.
