I was able to draw what I wanted in sheet metal but now it won't flatten properly. Does anyone know what I am doing wrong? Any input would be appreciated. Thank you
I added a R.10 fillet between arc and straight segments for loft (both sketches)
Rule of thumb for Lofted Bends - No sharp corners
Thank you for the tip and the quick replies.
I have a similar problem with lofted bend, but I want a edge flange on the curved edge; I can do it on a flat pieve of sheet metal, but SW doesn't let me click on the edge of the lofted bend to create the edge flange
On another note, I flattened your model and noticed in the slot holes you can see the thickness of the sheet when looking normal to it, this is really annoying when you want to export it to a laser cutting machine. How can this be avoided, the normal cut option was checked in the cut extrude but apparently doens't do what it's made for?
What is your version 2013??
Edge flanges do not work on bends. It would be nice if it did but then I suppose a lot of people would be designing stuff that is impossible to manufacture conventionally.
Apparently you are using 2015 if you were able to work with Peter's file. My flat pattern (Peter's file) has a normal cut. Not sure what would cause your issue.
I think 2014 was the first you could create a lofted sheet metal feature and add a edge flange, correct me if I'm wrong.
Applications such as a sheet metal transitions where you go from one rectangle/square size or rectangle/square to round were almost impossible to do prior to the SPR update. Now you can do your loft and on the straight sides you can now add an edge flange, insert holes or whatever you need.
I think you may be correct about 2014 being the first to allow you to put an edge flange on the edge of the bend of a lofted part. I probably should have been more clear. What I was trying to convey was that you can't put the edge flange on the bent (curved) portion similar to what you can accomplish with a swept bend. Of course you cannot (presently - have a feeling that is going to change) add holes to a swept bend and expect them to appear in the flat or unfolded state.
I look at Sheet Metal being used in Air Bending not stamping, which I think will be a mistake if they start using the Sheet Metal features for Stamping Features - Should be a new Feature entirely..
Agree. That is why I said we should not be designing stuff that cannot be manufactured conventionally unless there is no alternative. I'm sure many designers have had cardiac arrest when they get a quote back from a vendor that includes an $80,000 tooling charge and they only need 5 pcs.
