possible c-hook maybe?

[Bill Henderson]

I have some nasty inner elbow sheet metal that I am trying to unwrap. Solidworks fails miserably.

 

I have tried flattensurf c hook but it isn't correct. when I analyze the spline lengths before and after I find the flatten to be considerably shorter.

 

Is there a c-hook that may unwrap a spline?

 

Problem I get with solidworks is... the first edge is a partial ellipse on one plane with the transition on various axis thru to the end which is cylindrical on a different plane.

Thinking outloud here. Project the a grid of curves/sketch to the faces before flattening them in SW then analyze the curve length.

Solidworks won't flatten the sheet. For one it is an import dummy. The sheet metal feature is choking on the complexity of the shape.

 

I will try it again, but not much hair left...now.

 

Thanks

I am a dope.

 

The spline flattened should be shorter because of the shape of the original elbow. Hopefully it is correct.

Try flattening both ways -- in the along and across direction. The truth is somewhere in between The mid-line of the chosen direction will be true length, and the indivual curves perpendicular to that will be true length, but the outer boundary may not be accurate. There is no attempt to account for stretching (or compression).

Ive had a friend do it for me in Catia.

Send it to me and ill ask him reeeaaallll nice like
