TRANSITION?

[Anonymous]

Would anyone be able to tell me if there is any possible way to get a flat
pattern of a square to round transition? It would actually only be half of
it.

I've done two sketches, one of a half circle, and another, ( x inches off of
the plane with the half circle), of a half square. I then loft from one
sketch to the other creating half of my transition. BUT, inventor doesn't
like it when I try to flatten it out. Any ideas?

If you are going to work with anything other that square shapes in sheet
metal in Inventor I would look into an add-on to Inventor like SPI, Cobra
metal bender, AutoPol.

Chris,

Kent Keller has a 1/2 square to round example on his website. Maybe
this is applicable?

Don't use lofting. Use work planes and create sheet metal faces from these. split the round up into sections, don't square up the corners on the square and have them spit up equally also include the major faces as one of the splits. Make triangles to create the sheet metal faces. I have a square to round sheet metal pattern that will unfold but there is somebody else that I believe made one simpler. Mech_D
