Need Help offsetting a curved face for a punch and die style mold

Anonymous — Fri, 27 Apr 2018 15:15:50 GMT

So for the life of me I can't figure out how to get this to work. I need to either create a separate face with an offset distance of half an inch. I cannot use the extrude command and the offset tool doesn't do what I want it to.

This is a skateboard mold. The deck itself should be represented by a half inch thick offsetted solid, and the bottom half's face would represent the half inch offset of the first half. I have a copy of my work, a screenshot, and a diagram from DIYskate.com that probably better explains what I mean.

:EDIT.
On a mobile phone, can't get all the uploads to work so I had to link to the images.

Thanks for your help

Rectangular pattern the bodies and create a new rectangular body. Combine the new patterned bodies with the new rectangular body (I called this ADDED) with a cut option.

See my file below.

Also, use components, it will make your life much, much easier in the end. Sorry, I would explain better, but I'm about to leave. Thought I could drum something up for you really fast. Let me know if this doesn't make sense.

operations related to offsetting faces are very sensitive to the quality of the surface, and fail if there is any weirdness. Just so happens that using fillets as as modeling features is a common source of weirdness in surfaces, so that was the first thing I checked. fiddling with the values for the 2 fillets allowed the surface to be offset.

@DDMFGCOINC-Don't think that's going to work for the OP. You've basically copied the surface and moved it up. The mating surfaces of the mold will have different shapes (ie - they'll be offset surfaces) to allow for the material thickness being pressed between them.

@laughingcreek

You are correct and your method is the proper way of addressing the issue, espsecially the radii offsets.

I mearly copied the profile, given this is for a skateboard press, I figured this would suffice for the purpose. Thanks for updating the answer, for others that may use this for mold making reference!
