Hi Nikita, I'm a seasoned polygon modeler and am new to Plasticity. I have been going through your helmet modeling course. I've got to the bit where you are building the hexagon meshes.
I went off on a tangent and found a much better way, which I thought I'd share with you.
The process would be something like this:
- Patch the hole to create a sheet (but don't thicken yet)
- Select the new patch in face mode and hit 'F' and find 'Unwrap face'. A new flattened curve will be created somewhere near the origin.
- (optional) select the patch again, 'Untrim' and 'Unwrap Face' again. I found that the process would sometimes fail, but doing this seems to help.
- On the untrimmed and unwrapped shape, chop it up with some curves etc.
- Once you're done select the curves. Selecting the faces you want to keep and pressing shift-d gives you what you need. Then also select the untrimmed patched face.
- Hit 'F' again and 'Wrap Face'. The flat curves are now perfectly projected onto the curved patch.
- You can now select the face, add some thickness and delete all the unnecessary bits.
Works like a dream.
It's a beta feature so may be prone for failure. Hopefully the untrim workaround will not be necessary in the future.
And now that I think about it, you might only need to untrim when wrapping the shape back on, which would simplify things.
