Creating sheetmetal flanges on cut angles

I am trying to create flanges on the inside of a cut angle from a contour flange based drawing see attached file.  I am not able to get the flanges to attach since the material thickness varies due to the cut.

First, learn to completely constain your sketches to avoid problems later.

Then use Cut Across Bend

Then you will be able to add your flanges

Uhmmm, I don't think that will result in the correct geometry.Cut across bend.pngCan you attach your solution here?

jason,

If you model with obvious symmetry about the origin and use geometry constraints like equal = and colinear you can use far fewer dimensions to control your model.

Thank you for the help I get the same issue following your example.  I am trying a few things to get the plane to cut straight across and not down so it cuts on a 45 straight across on the left and right side.

Hi! Here is another way that I tried to add flanges to a sloped edge. See attached file.

I have done a few things like this using a surface then using the thickening comand. to make sure it is completely flat.

Forum,

 

 I have consulted my Inventor book and researched the forum to my problem and this thread was the closest I've gotten. I have several sheetmetal parts in which I have to create a flange on an angled part. And I have tried just about everything from different flange options including the loop option which I had no success with.... to attempting a face which it would not create beccause it is a non-manifold edge... to using the cut option differently so it would cut across the bend but this would not work because it only cuts the thickness of the metal and I need it to cut all...to finally resorting to exporting the flat pattern of the main face into AutoCad and drawing in the flange manually.

 

If there is another thread that can give me a hint then please post it. I am attaching my latest attempt as well as the dwg I have to go by. 

 

Thank You,

Not only that,when I try to create the flat pattern it errors that the topology belongs to more than one bend no matter which way I try to cut the angle....or which face...cut or extrusion...

Hi! It looks like you are on 2012. Could you upgradte to 2015 or 2016? Sheet Metal Cut Normal feature would resolve this requirement easily. For 2012, you can try a technique with good result.

 

1) Move EOP to right below Cut1.

2) Go to 3D Model -> Thicken -> uncheck Automatic-Blend -> Intersect -> go to More tab -> Automatic Face Chain -> select all outside faces -> Distance = Thickness.

3) Repeat step 2 for inside faces.

 

Now the cut edges should be ready to create flanges.

Thanks!

Johnson,

You are replying to a 4 yr old thread - not the new "hijacked" problem description.  The secondary poster appears to be using r2015 Service Pack 0  (it might be a good idea to update to SP1 and Update 3).

You are a lifesaver!!

Thank you for teaching me what I didn't know!! I will use this method in practice several times in the next few days. 

 

Thank You,
