Recently I had to design something in solidworks in sheet metal, but somhow my solidworks doesn't want to make a flat pattern.
This problem didn't occure in the past, only recently, does anybody know what could be the cause?
I added a test part with the desired bends in it, but the flat pattern wont come out and if I only add one bend in it, the flat pattern will be wrong.
Thanks in advance,
I've inserted the convert solid again and found a problem in the corners.
At the sheet-metal feature, check auto relief, 2mm obround.
Unfold, select face and bends
Make a cutout at the corners so that the plat does not intersect itself
Normally you should use the closed corner feature but this feature did not seem to appear.
You began with an block and after that you made your part sheet metal. What you should do is start with a base flange, and then make a milter flange under the angle what you like (select 3 edges at the same time).
You will have more sheet metal features in this way.
The corner as a flat pattern should look like this:
the : Constant Width
a couple of weeks ago my methode worked fine, but now for some reason it doesn't, maybe I have to reinstall the program cause it is failing?
okay I tested it and it doesnt work, the strange thing is, that both ways (the one I sended in as question worked before and now it fails) and now your suggestion also does the same
Is it solved right now? Normally you would use the features under "corner" in the sheetmetal tab for that. If that fails you can use unfold and draw a tab by hand and fold it back.
I couldnt make a cutout because that will result in a gap in the corner, the corner needs to be welded with TIG so Ii have to keep everything as tight as possible.
the problem is that the plate intersects itself. At the milter flange feature put the gap distance at 6, after that unfold, draw a tab (play with the dimensions, i've tried a little but its not perfect.) and fold to close the gaps.
*it should never intersect itself but with the drawn profile it does. It is a problem with the model that if you use this angle, sw can't close the corner properly so it has to choose between two errors. Like you can see after you draw the tab, it will become a very strange shape.
The problem is that I have done this several times but now in this version it doesn't work properly, the flat pattern isn't right, a corner wil never intersect with itself ever but somhow solidworks manages to make that happen
Try using the correct "custom folding area". Or reduce value of "loss to fold"pict 2. (google translate sorry)
