Sheet metal corner relief and self intersecting flange
Sheet metal corner relief and self intersecting flange
(OP)
Hi,
I'm drawing a two part sheetmetal enclosure consisting of a folded and flanged bottom part and a lid. I would like to have the bottom part's edges folded at 90 degrees with a 45 degree relief cut.
Here is an example : http://www.exmachina.qc.ca/enclosure.jpg
Unfortunately, any combination of flange, cut and/or corner seam I make always results in a "Flange body intersects the existing body" error. I can still make an apparently functional flat pattern out of this part but I would like to get rid of the error or find a better way of modeling it.
Thanks!
Tobie

RE: Sheet metal corner relief and self intersecting flange
I have had a look at your model - please send me some dimensions so I can model it myself and see if I get the same error. Which Inventor are you using?
I also need the following info from your sheet metal style settings:
1. Thickness.
2. Bend radius.
3. Relief shape.
4. Relief width.
5. Minimum remnant size.
6. Relief depth.
7. On the corner tab - Relief shape.
8. Also the Relief size.
If you let me have this I'll see what can be done for it.
Regards
RE: Sheet metal corner relief and self intersecting flange
Here are the value to the parameters you mention. Btw, whatever values I use I always get this error as soon as 2 flanges intersect on the same plane so I'm guessing the problem has more to do with how or in which order I apply the features. Oh! and here you can download the last version of the part I'm working on.
http://www.exmachina.qc.ca/enclosure.ipt
Inventor 10 Pro
Thickness = 1 / 16 * 25.4 mm (1/16" in a metric drawing!)
Bend radius = Thickness
Relief shape = default
Relief width = Thickness
Minimum remnant size = Thickness * 2.0 ul
Relief depth = Thickness * 0.5 ul
corner tab - Relief shape = no corner tab visible (not using a corner seam in the last version)
Relief size = n/a
Many thanks!
Tobie
RE: Sheet metal corner relief and self intersecting flange
I hope I'm not telling you something you have already tried. When are you getting your error? Is it when you create the flanges or when you create the seam? I can't download the part from the link you gave all I get is an html doc with giberish.
