Turn Swept face into sheet metal part, or a get a flat pattern.
Turn Swept face into sheet metal part, or a get a flat pattern.
(OP)
Through help from this community I have created a swept face that represents a face on a piece of aluminum crown moulding we are to build. I now need to "flatten it" so I can get a pattern to cut it out. I'm having difficulty converting it to sheet metal to do this.
Any help is greatly appreciated. We were supposed to have already started this thing, but this part is holding us up.... or I guess it's me thats holding us up :(

Bends require radii rather than sharp corners.

I'm down to the wire this morning on giving the shop guys a pattern.
Thanks again,

Dan, you would learn a lot by going through the SWX tutorials, all of them, especially the sheet metal ones. You will quickly learn not only what can and cannot be done, but why. You will be pleased at the rapid skill development you will gain by going through these.

Being able to unfold & get flat patterns of complex curve shapes is
what we are really looking forward to.

If you really need that function go to h
I strongly urge caution in jumping into the complex without much background in ordinary sheet metal. Do a cram session for a few weeks if you have to get fairly capable with the basics of SWX sheet metal. You will not only learn what SWX CAN do, but you will learn a lot about sheet metal in the process. Bypassing these basics is like using FEA just because you have the software. The software is not a panacea; you still have to know what you are doing.
Good luck.

I appreciate the time you've given.

A co-worker pulled up a drawing someone did in the past of almost the same thing...except the radius and line length are different. Apparently it is possible. They used a lofted bend to make it "sheetmetal" that can be flattened. I just need to back track their sketches etc. to figure out exactly how they made it work.
(see attached).

I didn't try to exactly match (as your dimensions didn't make sense to me - but check attached.

Thats awesome! I opened your files, but was unable to see any sketches, just imported parts. How were you able to get a flat pattern without making it sheet metal? Did you export this to another program? I would like to learn your method if you have a moment to explain.
As far as it not being symmetrical or the dims making sense....all I can say it that the geometry is per our customer and imported as it came to us. :)
Thanks for taking the time to help out,

I will try to post a SWx technique later today.
I did have to replace the spline curve you had with a circular arc curve (the difference was minimal as your spline is nearly an arc).
RE: Turn Swept face into sheet metal part, or a get a flat pattern.
I'm looking forward to it. Does SW not like splines for things like this?

Be sure you fully constrain your sketches.

I couldn't open the the solidworks file because I'm using 2009. I studied the sketches though and was able to recreate it on my end. Thanks again for all of your help... How long have you been doing this? Also, what have you found to be the best learning resource?
RE: Turn Swept face into sheet metal part, or a get a flat pattern.
SolidWorks since around 2001 (CSWP 2007)
I also teach Inventor and Creo (formerly Pro/E).
User forums like this. A larger variety of problems than you would see on your own and solutions from completely different perspectives than any individual is likely to discover on their own. Even if someone doesn't suggest a solution that is exactly right - it often sends the thought process down the right road.

O.k. your hired :)

Very well put.
Which of the 3 software you are familiar with has been the most helpful for you in dealing with sheet metal? Before I put everything into Solidworks, I want to know if in your opinion it is going to best meet our needs? We are a large scale custom sign company that does just about anything you can with sheet metal. However we only rely on 3d software for things like complex curved faces and cornice work. I'm especially interested in your opinion because you teach Inventor. I've had that in my mind for awhile since I'm a long time Autocad user.

RE: Turn Swept face into sheet metal part, or a get a flat pattern.
I found the solution to be creating this same shape through "lofting" instead of "sweeping". The sheet metal tools allow you to make a lofted bend this way. It didn't make a whole lot of sense to me why it wouldn't work the other way too, but alas....some things just have to be done the way this programs likes it. :) And I'm finding much more success in accepting that. You can see an example of working lofted sheet metal shape if you look at the post earlier in this thread where I uploaded a file pulled up by a co-worker & in the exemplary images uploaded by Rollupswx.
