Re: WHY WONT THIS SHAPE EXTRUDE

The profile should now extrude fine.

 

Very rarely do I use Mirror tool in Sketch environment.

If you count the number of mouse clicks I will wager my technique was fewer clicks that that on the YouTube video.

 

In any case, Inventor often has trouble combining coincident points when using Mirror.

If I need a Symmetry constraint - I will add it myself rather than doing Mirror.

If we assume (which I think is a safe assumption) that the design intent was really  for those arcs to be tangent - the curve is just slightly different.

(both curves shown)

Hi JD,

 

Mm.. I would have expected a "thank you" or similar sort of reply to your posting from him..

 

Anyway, I hope you'll still read this old thread..

 

How did you make that arc feature tangent to the the filet?

Did that depend on where you put the first 2 points of the arc?

Or did you constrain that?

Click the points for the arc anywhere except for the endpoints of the existing arcs.

Then add the Tangents yourself.
