The attached rhino 3dm file has a solid that is to be milled from solid block mdf. I need to create a ‘moat’ around the black line object, 12mm or more wide and perhaps 5 to 10mm deep (cutter ball is 12mm) or take the entire solid beyond the black line in by say 5mm or more.
How best can I do this ?
Here is an image of the file attached.
I wondered about sweep1rail and use a sphere, if I can get it to remain perp to rail, spheres have no tangible point and orientation to use, or do they ? or maybe a drawn shape.
How would a shape know to remain perp to rail ?..perp to surface in fact ?
A jing video of this would be sure welcome !
Fibreglass matting will be laid over this and the client will need to have some edge indicator so as to trim it to the black line shape afterwards, so a nice fall off at the black line seems sensible !
The lumpy surface by the way is not poor workmanship but deliberate !
