split the mesh with the projected curve not working

HeavyMetalFox — Sat, 06 Feb 2021 05:11:48 GMT

I am trying to project some curves on a a helmet (polygon) and split the mesh with the projected curve.
It works fine when I project the curves on the geometry but when I want "split the mesh with the projected curve" it only works with one projected curve (first one), when I try do the same for the second one, I get an error message and nothing happen (geometry is super clean) any ideas on how to fix that?

Step1. Project all the curves from any Aurthographics Viewport.

Step 2. Use Split Mesh with projected Curves Option box and choose Split and Detach Edges

Step3. Go to Mesh Menu and use .

If you want to slice the geo then from the side view you draw EP curve straight line not circle, circle profile is looking down. That will not work. If you rotate the circle and scale it down to a hole shape the it is going to create a hole through it.Draw EP curve not CV curve from the side view and use the same method. Let me knowepcurve position in red

Si drew 4 linear EP curves, did the projection from the right side, but still same issue with split mesh:

It worked! I guess the trick is to do all the curves in one shot 🙂
Thanks alot for your help man.

running to the same issue again, same helmet but different curve position, any idea on how to overcome this?

The overlapping lines are confusing the projection. will not work. Tested with parallel lines, needed scaling the lines wider , from the side view it worked. Since you are trying to cut straight lines you should use the multicut tool and draw straight cut. Faster and easier.

completely forgot about multicut!
Much thanks for you help sir.
