Curve Bend Help

[Anonymous]

Hi,

I'm currently using Autodesk Inventor 2013. The main bend I'm trying to achieve is the back bend (curved flange). I have in the past managed to create the side bends just fine but the back flange just doesn't convert to sheet metal to allow a successful flat pattern.

Any help would be great!

Thanks

This is very poor modeling technique.

Sketch1 is not constrained and this line isn't even horizontal?

And I would use all sheetmetal tools to create the part.

Thanks but I wasnt worried about sketch constraints at this stage as it was a quick model for a quick solution - maybe this was a bad idea. I have now attached a fully constrained sketch.

Through 11 or 12 years of experience I have found that my fastest modelers always worry about this stuff right from the beginning.  So there is nothing saved in an undisciplined technique based on the experience I have seen.

You have a number of dimensions that don't make sense to me as manufacturable/inspectable.

If you can fix these to what you really want then I can show you how I would model the part.

(my solution will be 3 simple features, one of the three will actually be a mirror of the second feature)
