Patch problem

I have simple closed curves that I need to patch but it gives me these results.

Am I missing something?

Hi @gurkan_bozkurt
What result are you expecting? You have two closed curves, and patch is trying to create a single surface that spans both those curves. If you are expecting two surfaces, run the operation two times. Also, you are 4470 km’s away from world origin in meters - that will cause floating point errors on most commands, so it might be a good idea to move your geometry closer to W0,0,0.
Here’s the result of Patch with the geometry moved to 0,0,0:


I don’t know if that’s the expected result? :slight_smile:

a further note might be questioning the need for patch in general, as it seems it might be a pretty straight forward geometry, why not draw the profile and loft or better extrude it?

There is some deformation on the steel and these points are the real life points that I got from site. Patch is for visualization mostly.

Thanks a lot. I forget about floating point thing every 2 to 3 months :DD
