Multi-part mold

Grasshopper
1

Hi all-

We’re a group of engineering students and we’re trying to create a grasshopper script which will allow us to automatically create a multi-part mold for any meshes we might import.

Now we’re still stuck at the basics and have decided to take an approach where we look for occlusions for mesh faces for a main parting direction. Here we use galapagos to find the part that gives us the least occlusions.

We’ve already tried to take the approach suggested by Laurent Delrieu and using isolines (Multi Part Mold for 3d model). This, however, presented problems when meshes get linked together with thin strips, making it impossible to make moulds out of them.

Any help would be greatly appreciated!

There some draft angle scripts in here that might help:

Hi Ftzuk,

You’re right, we’ve looked at this as well, adding draft angles is definitly on the to-do list.
