Request(?) opening geometry

DNU — Thu, 26 Sep 2024 11:24:09 GMT

I'm creating a label that shows the dimensions of an opening (created with the opening tool). This works fine for rectangular opening (width + height). But for circular openings the diameter must be shown (or just ∅ width).
Is there a way to find out what the shape of the opening is in a label?

For now i'm using a boolean in the label properties, I hope I can do it automaticly.

There seems to be no way, sadly. The "OPENING_SYMBOL_GEOMETRY" dict is not accessible from a label, so I don't know how to deduce it otherwise.

A workaround is to test the area and perimeter. The only downside in the unlikely event a polygon opening could have the same perimeter as a circle with the same overall width and height. But unlikely the case.

eps = 0.0001 !if a opening if GLOB_ELEM_TYPE = 26 then n = REQUEST ( "Property_Value_Of_Parent", "Builtin.General_Area", type, dim1, dim2, elementArea) n = REQUEST ( "Property_Value_Of_Parent", "Builtin.General_3DPerimeter", type, dim1, dim2, elementPerimeter) !if length x width is the correct area, then a rectangle if abs( (opening_width * opening_height) - elementArea) < eps then text2 0, -1, "rectangle " + str(opening_width,4,3) + " x " + str(opening_height,4,3) else !if circle then diameter should match if abs ( (2 * PI * (opening_width/2)) - elementPerimeter ) < eps then text2 0, -1, "circle diameter " + str(opening_width,4,3) else text2 0, -1, "polygon " + str(opening_width,4,3) + " x " + str(opening_height,4,3) endif endif endif

Thanks Mark!

This works perfect!
