Hi NightCabbage, no problem!

It can easily run into difficulty when thickening pieces made up of more than one surface, if the surfaces do not all attach to one another in a very regular angular pattern.

In cases like that you may need to separate the model into individual surfaces and thicken those surfaces - the thickening of a single surface should not run into the same kinds of difficulties.

Hopefully in the future it will be possible to thicken multi-surface objects more easily than what is done currently, but it will need a pretty big upgrade to the shelling component in the geometry library that MoI uses which is licensed from another company. I do have a request in to them with several examples to ask to improve this area, I'm not sure when that will happen though.


Shelling a solid works in a different way than trying to thicken a surface, so sometimes instead of thickening a surface you may want to finish the surfaces into a basic solid, then perform the shell on the solid. The sheller is more able to make clean matching pieces when there are side walls available to cut pieces with.
