Boundary Surfaces - Substraction Problem

Hi everybody,

i was trying to substract one geometry to another (to be precise the windows from the walls) using the boundary surfaces components and i got the following error:

As you can see from the previous images, in the first one everything seems to be nice, while in the second one (with a lower scale factor) i got the error...

It seems that more i reduce the interior gometry and more i get untrimmed surfaces, which are wrongly counted as wall in my case.

I have tryed also to do it just for one wall and one window but i got the same problem.

I have to say that the geometries are built in Rhino (not through Gh) but they should be coplanar (windows and walls).

Any suggestion?

Thanks a lot in advance

Claudia

Claudia,

Make sure input curves are flattened and are on the same plane. You can project them on the plane before trying to create the surfaces.

Mostapha,

Thanks a lot for your answer.

Actually I have copied and pasted the surfaces (walls) in order to create the windows and then i scaled them. So i guess they are on the same plane, but i still have that issue.

Can you have a look on the file?

I attach it here

Thanks a lot

Claudia
