sweep issue on ellipsoid
sweep issue on ellipsoid
(OP)
With reference to the attached file the sweep fails as soon as I add dimensions to the initial ellipse sketch. Why is that? I was able to dimension the sweep path (the line) thus having some but not full control of the aspect ratio of the ellipsoid. How can I fully dimension this solid?

I've seen the issue you're having before, but don't remember the cause. Not sure, either, why my solution works, but it does.

This is a workaround I sometimes do if I can't get the solid to work. Then I send the problem file into my VAR.

Rob, I wasn't able to play with your file as alas I am in the SW-08 dark ages! Thanks for the jpeg.

In general surfaces are more powerful or certainly more appropriate for certain situations. If the model does what it needs to do and is not too convoluted then there is no reason to redo it with solids. I hope this helps.

Did for Tips&Tricks presentation in 2008 if I have model I can attach but the pictures below show Path& Guide sketch Circle as path and Ellipse as Guide Curve then draw closed Partial Ellipse Dimension the third radius and pierce with guide curve.
In order to select a portion of the multi profile sketch right click while selection is active and Choose Selection Manager shown in image below. Options are
icon1 Closed Loop, highlighted
icon2 Open Loop,
icon3 Group Sel(allows 1by1 selection),
icon4 Region, and icon5 Regular Selection (entire sketches/features)
If you do with 2 Flex Features which is also possible there is a display bug where the Ellipsoid has a line down the second squish or stretch feature along the Sketch plane.

After installing SW10 SP 2.0 at home I opened your surface solution. I find the same oddity as in my solution - i.e., you can change the aspect ratio of the profile ellipse but you have to delete those dimensions or the sweep will fail. This is frustrating me to no end. Not looking for other soutions just an understanding of why this is so.

Here is a diary of my failed attempts which might be helpful.
First I tossed pierce, coincident, horizontal and vertical constraints everywhere. The model updated for everything except for the thickness of the ellipsoid. I then extruded the curves into surfaces so I could pick the edges. Still the same error. I then extruded full ellipses and used a split line to cut them. Still same error. I hope this helps.
