Morning all,
i have a surface imported as SAT in Rhino that i want to intersect with a series of planes
When i use Geometry.Intersect i only get partial results (meaning not all planes finds an intersection)
Using Surface.ProjectInputOnto (with Lines) i get the same result
Any idea why and how to fix it is welcome
Cheers
Can you share the sat and the dyn?
The DYN yes, the SAT complicated since it’s still not a public project
Have you tried intersecting with big enough rectangles rather than planes ?
I tried with lines also, same result and EXACT same intersection so it’s not random
Strange indeed…
If it is only about getting isocurves, I think Curve.ByIsoCurveOnSurface might work.
The only time I had a problem with intersections was when the surfaces I wanted to intersect where too big.
Different issue with iso curves. they don’t seem to respect the surface
And here’s what i get when i intersect the isolines with the surface
Quite weird that some isocurves seem to stop at the end of the surface whereas other seem to ignore the boundary…
Quick thought : Maybe your initial Surface is not correctly defined / imported and there are some “leftovers” points that we cannot see. Does the first intersection you made in your initial post contains any point ? If yes, could you highlight them ?
Does this happen with any other Surface ?
One more clue, here’s the Reference Planes with a solid generated from the same surface in Rhino
Same Surface, split in 3 using ACIS 2,3 and 4
Im loosing my mind ahahahahah

Hi Daniel. Why don´t you try with a simpler surface, just to discard an issue with its geometric definition (It happened to me once).
I’m not sure if this might help, but I usually export the Rhyno surface in a 3dm format when I need to create it in Revit.
One more test
Inserted the thickened surface then exploded it then…
Im getting more lines but still not what i need
Seems ok with a quick made up shape so it confirms that it’s on the Rhino side i guess.

If you can share the sat via PM or other non-public channels I’ll try and see if it’s a geometry conversion issue. Would only need that one surface.
This should work …
sat.dyn (16.1 KB)
Have you tried adjusting the geometry range in dynamo or scaling the geometry?

I ended up creating large circles and transform them into surface to cut
Hello, I have a similar problem and my surface is a very simple square face. Is this a problem because of Revit?
