I have made a sheet metal part in inventor (see image). I have made the part as it will be in the finished production state. The problem is that the part is impossible to bend from one single plate, so it has to be made from several plates and welded together.
What i want to do is to remove the four corner plates (denoted with red arrows in the image) and make a flat pattern for these separately.
The reason i made these corner plates in my model is to get the assembled part 100% correct. if i dont, inventor doesnt make the angles that i need between the flanges in the top.
I hope you understand as I find this difficult to explain.
Not sure why you are saying it cannot be created from a single plate.
Of course in Inventor it's possible, however in real life this will be very difficult to manufacture with the equipment we have available.
Treating this file as your layout, derive it into two new parts and lop off the 45° pieces in one file, and lop off everything except one 45° piece in the other. Then create a weldment as your finished part.
