I am trying to create a flat pattern for a sheet metal disc that will be rolled to Ø10 3/4". I can create the part, but the flat pattern fails. The component is highlighted in blue.
Could you upload your file. Demerge the disc from other parts and try.
What version of SolidWorks are you using to model this repad?
Convert to Sheet Metal.
2019 sp 4
I will try your suggestion
Convert to sheetmetal doesn't work for this profile.
No *.sldprt file Attached?
Here is the file.
For a wrapped plate like this, I typically start with a base flange that matches the curvature of the cylinder and then cut away the excess.
When I attempt this type of cut, it doesn't allow me to flatten.
Did you look at the part I attached in my first comment? It flattens fine.
Make sure that you have 'Normal Cut' enabled.
here's how my feature tree looks when I try to unfold. I created a curved sheet metal item, extruded a normal cut, and it tells me I need a "fixed planar face or linear edge"
I tried using Intersect Feature then convert to Sheet Metal, but that did not work at all.
We can throw that option out the door...
I did a lofted bend to create the tube and then did a cut extrude thru that tube. It left some odd geometry at what would be the normal bend line but appears to work.
So, what was the magic that made it work for you?
I found 2 curves are overlapping I made it one curve it worked. I do not know the reason.
Thats good news and bad news at the same time.
We know you got it to work, but we cant replicate it at the moment.
The way I got it to work is to start your original part with a square sheet metal part.
Then sketch a circle with a square bigger than the first sketch so that you can cut everything out and keep the circle.
The flat pattern still exists so just unfold it and its flat.
Edit: I'm copying Chris England's post because it shows it better with a picture. Make a square sheet that is already curved to start with.
