when i first got the stl 53 days ago, i just imported it right into SU pro. I then made my changes, got rid of the non NIH approved stuff, added what neded to be added and then exported the stl. It was a little tough because of how many face, etc it has.
When i imported it, i looked for a units option and found none, because i usually work in the metric system.
I have not run clean up 3 on it. Is that an app or an extension?
I have the idea in my head of HOW i want to do this, but i cant seem to grasp the concept in SU. In the real world when i have seen it done, they cover the sides of the mask with clay, then fill int inside cavity with either resin or some sort of plaster. this makes the inside part of the mold, then they flip it over, pour resin or plaster on the outside of the mask. this makes the two pieces.
Im not gonna give up on this because i need to learn this for other applications i may run into and i dont like to give up either haha
below is an image from smooth-on. this is not my mask but the concept im going for.
