Mesh/Plane Intersection Issues

Hi All,

I am new to grasshopper and am having trouble with the Mesh/Plane Intersect command. I have two meshes and a series of planes extruded through the the meshes. I am trying to calculate the intersections so I can sweep them later to create a surface. For some reason I am getting an error message from the plane side of the command. I have used this command in previous scripts and I compared the input data panels and they seem similar to me. If anyone assist me with solving this problem or recommend another method to trim outside the meshes, it would be much appriciated.

I will post my script for reference.

Thanks,

Pete

I think the problem might be that I am attempting to calculate the intersections of a brep and a mesh, rather than a series of planes and a mesh. However this realization does not bring me any closer to finding a solution to the intersection problem.

Hi Peter,

It seems like your project could be done without the use of meshes. Have a look at the basic waffle script I attached to your other post for reference.

I don't think your problem will be easily solved here, because what you need is a series curved surfaces to intersect with other surfaces. Using the mesh / plane sectioning won't be possible with what you have, since applying a single plane to your curved surfaces is impossible.

I suggest going back a bit and rebuilding this script using only surfaces, so that later if you want to find the intersections between them, your geometries will match.
