How can I add seam allowances in duct designs without collisions?
I am designing a bunch of ductwork parts for 24ga sheet metal for hand assembly (not welded), and I can't figure out how to add seam allowances for something like a Pittsburgh seam. In a flat layout, I'd just add 1" on one side of the rip joint for the pitt and 1/4" on the other side of the rip for the flange. But when the…

Partial Sheet Metal Hem
Battled with this one for a while before landing on a solution. There's no partial hem capability built in, but the same can be achieved by notching the bend relief at each end of the partial hem then hemming the remainder. Posting it here in the hopes that anyone struggling with the same problem can find it since my…

Sheet metal adding weird extension to my part...
Hi there, I trying to mock a drone and to build it from cardboard. I have a laser cutting machine that I will export DXF from Onshape. I built the part, and with Sheet metal, I used the Convert option. I wonder why the sheet metal add this two long beams at the back of my plane. Any ideas what I am doing wrong? Thanks…

Preserving Attributes on Sheet Metal Parts in FeatureScript
Hi, I have a sheet metal part where I set custom ids on its surfaces so that i can keep track of them : setAttribute(context, { "entities" : faceOfASheetMetalPart "name" : "CustomId", "attribute" : "aCustomId", }); That works great, but when I apply fillets to the sheet metal, the attribute disappear. How can I keep track…

Can't get "isSheetMetalModelActive" function to work
I am trying to check is a sheet metal part from a query is active or not. It seems isSheetMetalModelActive() should do the job. My problem is it always returns false even when I know for sure the selected part is active. Here is some sample code I have been testing with. precondition { annotation { "Name" : "Sheet Metal…

"Machine Ready" Sheet Metal Drawings
When I finish a sheet metal object and insert it into a drawing as a "flat" sheet metal object - it contains all sort of stuff like text, dimensions, arrows, center annotations and fold lines I do NOT want my laser, plasma or water jet to see. I usually go in and delete all these manually, which is always tedious. Is there…

SHEET METAL BEND - CANNOT UNROLL A SIMPLE BEND
I am using sheet metal in OnShape the first time and trying to unroll a simple bend. The arc and line are tangent. Seems like this should be a trivial thing to unroll, but it refuses to do so. Am I missing something?

Downsize large step files
Hi together, i export step Files (sheet metal part) and send them to producers. The step files contain a high amount of surfaces, that makes the step file pretty large and the producers cannot handle it. How can i compress a step file to get a smaller step file size? Attached the sheet metal part, it has 12 MB, i need it…
