Surface from 2D imported (DXF) shapes, issue...

[Masoud 14]

Hi;

I tried to create a surface out of my imported shape (e.g. a DXF file) using a "Planar_Patch_From_Curves" SOP, but it fills the inside shapes as you can see in the image below.

How can I fix it?

 

Thanks for helping.

Hi "Tesan";

Thank you for your reply.

Your solution is helpful in this case, but is there any solution for complex shapes with a lot of inside shapes?

Hi,

you can also use intersect_all function, to detect the number of intersections, which can help you to find the inner prims, but this function works better with 3d geometry, so it might be better to extrude your shapes before you use the intersect function.

or it could be this simple...

Thanks to everyone;

Your solutions are very useful, but it seems Houdini needs some new nodes in dealing with such shapes.
