Hi all,
I am working with a model of a tooth, with some interior cavities reflecting the pulp area, and the root canal leading out.
Specifically, I am stuck trying to edit the mesh so that the root canal (but not the pulp) is much smaller/tighter. Like, decreasing the internal diameters. The tip inner diameters should be ~0.2 mm, and the pulp opening inner diameters should be ~0.5 mm.
This is the workflow I've attempted so far:
- Since I can't figure out how to select the internal faces, I selected all surfaces, then slowly brushed away unwanted surfaces, then adding a smooth boundary operation.
- Next I tried to just do an extrude.
- Finally, remesh/smooth my way to transition the boundaries.
However, I realise that there are some parts in the middle of the root canal that start off thinner than the endings, so using Extrude (Direction = Normal) to sufficiently tighten the outer parts end up sealing the middle parts:
I think maybe selecting this section as its own FaceGroup and adjusting it may be a solution, but I cannot figure out how to select this inner wall section.
Would anyone be able to help, or suggest alternative workflows?
I have attached my .mix file if anyone would be kind enough to give it a go.
