Nathan Chandler - Help with Ellipsoid Project

[Anonymous]

Hello,

I am trying to follow along with Nathan Chandlers "create form ellipsoid" demo at https://knowledge.autodesk.com/support/fusion-360/getting-started/caas/screencast/Main/Details/07797... and I am having problems with my sketches.

The sketches were created as follows

Make line 1

Make line 2 at 90 degrees from line 1

Make ellipse using origin, line 1, and line 2

trim ellipse once (removes 1/4 of ellipse)

Trim ellipse a second time (removes 1/2 of ellipse leaving me with the 1/4 I want)

I do this same thing on the X, Y, and Z plane

I end up with three sketches that to me appear to be the same as Nathans with the exception of the two dimensions.

When I go to construct the loft everything falls apart when I select the rail. The error I get is "one or more rails intersect a profile more than once."

My problematic file is attached. Any help the community could offer to a new user would be greatly appreciated.

Sketch 1 and 2 are OK,

The error is in Sketch 3.

Loft is for all of us, just plain FINICKY. You must snap to the point from the other sketches, if you looked closely at Nathans video, the purple points are there.

Delete everything from sketch3, then 

Project the end point of the top curve, and the end point of the lower curve into Sketch 3, hide the first two sketches, or the snap will always attach to the wrong one,  

create the rail curve Snapping to the two purple dots in the sketch, trim and

The loft worked here with this method.

Might help....

Check out this screencast and let me know if it helps! Sorry for the misteps, it was my first go at it!

I hope that helps.

Thanks,
