Dear all forumers,
I find that the flat pattern of my sheetmetal seem incorrect. Please help me.
I believe it's because in your original model you cut the cylinder down into the material and stopped. This left a square edge inside the thickness of the material and when the part is flattened, you get that square edge. If you change the diameter of the cutting cylinder to 362 so the end of it is not still in the material, then you get the rounded ends as you show in your last post.
Good morning Sean,
Do you mean the flat part in the flat pattern?? When doing a part like this in Sheet Metal SolidWorks does not taper anything, it make the edges straight.
If you aren't sure, print the flat pattern and cut it out and fold by hand, than you can see how it will look.
Looks correct to me.
I suspect that what you expect is for the cut to exactly match the cylinder cut you put in and that's not going to happen because you can't cut down into the thickness of the material like that. What is happening is that a large enough cut is created in order to let the round cylinder fit. It will not be a perfect fit.
I don't understand why the smooth edge after flatten become a straight edge. I thought it should be a smooth edge too. Please see my 2nd part.
Thanks a lot.
Wayne is correct, if you make the cut "thru all" and change the diameter to a bit under the OD of the part, then the cutout will have a smooth radius for a "not normal" sheet metal cut. In actuallity, the smooth "not normal" sheet metal cut would not properly fit unless you also removed the edge straight through the part as shown in the model. I have attached a copy of each of these parts for you to checkout.

not normal SM cut
Dear Wayne and Chad,
Yes, you are right. I resolved the diameter and get the right pattern i need.
