I have a problem in converting a sweep into sheet metal and creating a flat pattern also went to the user group and found a possible solution example (solution ID: S-052893), but the flat pattern does not look right.
Could someone help with my part file please.
Thanks in advance

Hello Kelvin,
Thank you for your reply. Your sheet metal part is very similar to the one I previously acquired, but yours is much better, it does the flat pattern perfectly.
Thank you very much.

Good afternoon Serge,
Your assembly should consist of different components rather than a single body. That way you can work with each part or component independently. You can use the part that you uploaded to act as a dummy part then you can make your new components of that part.
Do your flighting based on what Kelvin posted above and after you create you flighting as a sheet metal part un-fold if you can and add the cuts for your vertical flats, if you find an easier way then by all means do it.
Later,
John
Hello John,
On one or two previous sheet metal assemblies I've approched it with two different method. One with skeletal modeling inside the assembly, which I prefer, and the other is like the one I just posted. But because I'm pressed for time to finish this project, I didn't want to start from scratch.
On the other hand I may have to.
Thanks again.

Serge,
I believe you will need to shorten up the overlap on your helix, otherwise the flat won't work out. The only time you get more than about 1.05 revolutions is when you have a tapered helix that doesn't overlap. I used your model to create 3D curves driving lofted bends and it wouldn't work. When I created new helixes on top of your geometry and stopped them shorter than your model, it worked.

Hello Glen,
Thank you for your reply. I think I have to disagree with you (no offence), yesterday I started a new helix using the sample that Kelvin attached to his message. I modified his to suit my design exactly as the original and this time it does the flat layout perfectly.
Serge,
No problem. I'm glad you got it to work. I used the auger model as well but noticed there was limited amount of overlap before it would fail, I did not however, change it to match your geometry exactly. Since I started playing with it yesterday I went on to make an 8 revolution tapered helix and cut it out on the laser.
Cheers,
Glen
SW cannot recognize that method as a sheet metal part. You will have to use the Lofted Bend method per the example shown in
