Hi! i’m doing this kind of BIM for building a model for building with straw.
I want the user to draw the line of the wall, windows and doors, and have the model ready to print.
But i cant find a proper way to cut lines of windows and doors, from the wall line.
I tried remove duplicate curves, and either is not working properlly or i’m making a mistake i can’t see.
It worked the first time with the original polylines, but it’s not working with the offseted lines.
This are the hihglighted lines i want to filter out.
But the result I get is this one. (marked in red those that filtered wrlongly)
You can see in the inner wall what i want to achieve.
This is the setup i used:
This is the file:
There is a toogle button to b ake the geometry into the proper layers, its signed with an arrow and a circle at the left of the screen.
The group where im referring now if in Red colour, and in Blue is the same setup working properlly.
