I am working on an automated workflow that creates standard 2D detail drawings from 3D input geometry. The Make2D Grasshopper component is having a lot of issues especially when trying to use a clipping plane with it. The common error message I am getting is: “Solution exception:Object reference not set to an instance of an object.”
I’ve narrowed the issue down to a problem with the geomtry that intersects the clipping plane. So it might be a data mismatch where the clipping plane doesn’t look at each item in the set. I tried to get around it by flattening / grafting / exploding the geomtry but this results in the hidden vs. visible lines being all mixed up (see attached image).
Thanks in advance for any ideas!
