Hi guys,

Here is a problem I spent an hour trying to solve, and couldn't do it. Maybe you'll have an idea.

I have this cylinder/tube:

See the cut at the top? It almost looks like an angled plane, but it isn't. It's an ellipsoid or something, it was caused by taking a cut of a bigger and more complex model that I won't go into.

Long story short, I want to make a true angled plane cut on that cylinder, that's going to be as close as possible to the complex cut. (i.e. an approximation.)

I was basically thinking, take the highest point of the cut and the lowest point of the cut. Make a line between them, and a line from each of them to the flat bottom of the cylinder. Take the plane that intersects the two points and is perpendicular to the plane defined by the 3 lines.

But, I don't know how to define in solidworks "The highest point in the cut". I want the point in the circumference of the cut that's the farthest away from the base of the cylinder. How can I mark that point in Solidworks?

Thanks for your help,

Ram Rachum.

If I understand your question correctly, this is how I'd do it. I'm not sure about the nature of the cut you have, so I just approximated something that sort of looks like yours.

NOTE: in my model, there's some problem. I can't get the lower edge to project into the sketch plane, or make any sketch relations to it.
