If you’ll let us know the specifics of the difficulties you are having we’ll do our best to assist.
To work with MeshCAM we’ll need to know what platform you are on, and what you would like to use for a CAD solution — I don’t use many, so would likely need to do an equivalent design using one of the applications which I do use.
Please note that we have a standing offer — if you get stuck on a file or project send it in to support@carbide3d.com and we’ll do our best to work through things with you — that’s where most of our tutorials come from.
