I think I am having the same here! Took my whole day, I’m going nuts. I wanted to generate plan views.
When reproduced then 2 intersecting cubes but it is working for cones for a strange reason. When the view seems to be different than the clipping plane it works nicely. Video and .gh attached. Pleasetest-overlapping-plan.gh (205.7 KB) help!
I think this issue has been reported many times in the last few years. As it stands I think you cannot generate sections or plans with grasshopper, only isometric projections. I really hope someone will have a look at the video where I reproduced the bug also the script to demonstrate it.
Can you make a youtrack for this please?
This is definitely a bug. I just tried with ‘HiddenLineDrawing’ and if clipping plane is parallel to the view plane, then either clipping plane is ignored completely or an error is raised on any call to Rhino.Geometry.HiddenLineDrawingSegment.CurveGeometry.
I assume this is what happens to the Grasshopper “Make 2D” component as well.
I think I’m facing the same issue too. I can’t manage to get clipping plane input working with Make2D component. I attached below the .gh definition to reproduce the error. XY planes seems to work, but not XZ or YZ planes (planes are always parallel to the view, see the screenshot).
Make2d works, the problem is within GH make2d.
Parallel clipping plane cutting right angle planes…
It is also happening with two different sized cubes, first I thought it may be overlapping surfaces that is causing the issue.
I think it is a bug, too, it seemed to abrupt to be true, how is anyone using the GH make2d component for generating ANY plans or sections?? I thought it was my green ears… Burnt an entire day trying to fix my script and test / reproduce it trillion ways.
Can you point me into direction? Also what software is everyone using for recording the screen? They seem be the same with the yellow highlight on the mouse pointer, is it built into Grasshopper?
