V5 (with layer bug)
So as to reduce the cost of 3D printing where volume of material used is a factor in the cost, I need to hollow out my solids.
I use OffsetSrf, decide on 4mm, then struggle on how to use that to hollow out the solid.
Boolean Difference, select outer shape, then for cuting device, the inner shape, it fails…says
Objects do not intersect nothing done
Boolean Intersection, select outside shape then inside, nothing happens,
Boolean Split, select outer, hit enter, select inner, get Boolean split failed.
Boolean Split2, select both and a translucent effect occurs, ( I was in Ghosted mode though other Booleans didnt go translucent) accept first. but nothing has happened.
try again, this time click mouse once and accept this and hit enter. Nothing has happened.
Try again, click mouse twice and hit enter, nothing has happened.
Try again, click mouse three times and hit enter, nothing has happened.
One cant actually see which one gives a hollow middle.
What have I missed ? I have tried all Booleans, which are for solids. Trim I cant use as select item to trim disallows selection of the solid.
There has to be a simple way for this, where is it ?
Shell requires the loss of one face. I need 4mm all round thickness.
File attached…simple test, real item somewhat more involved !
