We build ASME chambers that have ports and tubes that intersect at various angles. When these tubes intersect at a standard angle, center on I have no problem creating the sheet metal layouts for the tubes. The attached PDF shows one intersecting at two differnet angles, off axis.
Can anyone help witht he sheet metal layout fo the tube part? I have modeled it pretty well, I just can't figure unfolding the tube portion. The head is a buy out item, we have that.
I have to ascertain two things ultimately, the hole size/layout (easy) and the tube (stumped).
I have attached a zip file of how I would handle this. Best practice maybe not but it works for me whenever I need to tackle sheetmetal development when it's a little challenging.
Basically I make a solid block (could be surfaces) of the inside or outside of the part I want. Then I use the Derive and Thicken tools in a Sheet Metal part to bring in the surfaces of that block. For a more detailed explanation look at my blog posting.
You have several other problems, namely with unconstrained sketches and not using Sheet metal tools and the ends of the material not being perpendicular to the material face. This latter point will cause issues if you send the part out to be plasma/laser cut.
