This error has me stumped for the last hour any help of where its touching or what is wrong will be much appreciated.
This error has me stumped for the last hour any help of where its touching or what is wrong will be much appreciated.
I'm using 2016 SP2 and it is flattening ok.
I'm assuming this has to do with your bend allowance settings. The bend that is failing for you has a 93° bend. When I edit the "Sheet-Metal" feature, this is the settings that come up in your file on my machine. Confirm yours are the same:
Personally, I change the Bend Allowance to Bend Calculation and select the Bend_Calculation library file.
I belive, bend allowance is related to the degree of the bend. So if you are bending all 90°, then the single bend allowance number works fine. But when you start bending at different angles, they require different bend allowances, or deductions if your using bend deduction.
By using the bend calculation, you are more free to design without error. If you want an accurate flat drawing, talk with your sheet metal vendor to get the bend information needed per each angle, then you can compile and use a bend table.
Side Note:
You can also greatly shorten your tree if you place the cut sketches in the flange sketches. In other words, modify the flange sketch after you create it. There is no need for any of the cut features by themselves. You have some funky things going on with Cut-Extrude 23 and 25.
So I attached the wrong save last time, this one has the bends correctly orientated but the warnings are still there. I can flatten the piece but when its not flattened it has the warnings, what effect do these have?
I had changed the length of the bends to 1mm to see if they were contacting at any point but I couldn't see any so I continued with the drawing as it should be.
Thanks for your help.
What error?
