I need some help.
I have a dumb solid (see attached) of a vacuum formed tray.
I need to 3D machine a block of aluminum that will be used to make this tray.
How can I get a solid of the negative of this tray?
Thank you in advance.
I would use offset surfaces with a value of .0000 and then thicken or merge with another surface..
Edited - Per Doug Seibel - his answer is the correct one - all I did is give you a solid in both directions...
Extrude, up to body. Be sure to uncheck the "Merge result" option.
Always another way.
Created an assembly inserted block and used mold cavity.
The extrude up to body also works in an assembly.
Assemble the tray into the assembly.
Assemble the "core" into the assembly (simply an empty part).
Edit the core in the assembly.
Extrude up to body, selecting the body of the tray part.
The "up to body" option for ending an extrude or cut can use internal (bodies within the part) or external (bodies in an assembly) references. It also does not need to be a solid body, surface bodies (knitted quilts of many surfaces) also work.
There are always many ways to do just about anything...
Create a separate body that covers everything you want a negative of, then Run a Combine and subtract the original body. (in a new part of course)
The Intersect command works great here.

This is the method I was going to use, it is one of my favorites - I really dig Doug Seibel's method as well . . .
I really like seeing the other options for the same results. This is the main reason I use the forum is to learn something everyday.
I also to get a good laugh from the responses in the other threads.
In my case most of what I do is injection mold related, so the old saying fits........"If the only tool in the tool box is a hammer, everything looks like an nail".
