Carriageway surface.3dm (1.1 MB)
Carriageway extrussion.3dm (9.2 MB)
Firstly, I used sweep2 to create a carriageway surface. I wanted to wirecut the opening but the curve / extrusion had been merged into the carriageway surface.
Later, I extruded the carriageway surface to a polysurface. I did the wirecut again but the same problem had still come out.
How to solve it?
Thanks
