80/20 Frame construction

80/20 Frame construction

80/20 Frame construction

(OP)
I'm working on a design of a frame w/ 80/20 alum section now, but I suppose it applies generally. Right now I have a library w/ various length of 80/20 section, which is fine until somebody comes and says great, make it 2" longer and a foot taller, then I'm switching stuff out and making lengths I don't have etc.

Is there a way to make the structure sketch driven, sort of like a weldment?

 

RE: 80/20 Frame construction

I have been working with 80/20 (actually prefer T-Slots where it fits). I import components and profiles from 3Dcontentcentral and the format varies. Sometimes it is a configurable length of a profile. Usually you get a parasolids imported section. I bring them in at 1.00", establish a plane in the center, copy the profile to a sketch, and extrude mid plane to the length dimension I want. I make that dimension a property for the BOM.
Since there is so much variation on holes, pilots, and other features, I just make a new PN for each version I need. That way, if that particular one changes, it does not affect any other assemblies.
After the last project I went back and tried to redo it as a weldment. Like dancing with an elephant, It can be done, but what's the point?
T-Slots is (possibly) working on an add-in for SWX.

RE: 80/20 Frame construction

Seems like creating a library of sketch profiles and using the weldment functionality would be the exact way to go.  I am surprised that the library doesn't already exist.

Yeah, weldments are the way to got.  You will have to create your own weldment profiles, though.

Good experience doing it as weldment. Haven't done it by creating a mess of new parts to compare, but I don't have a billion mates to drive me crazy either. You do need to get friendly w/ 3d sketching & find/create section profiles.

Side note: SWX will only generate a cut sheet if the weldment (part) has it's own view in the drawing. An assembly view that includes the weldment will not do.
