"more than 2 elements are joined at a single intersection" error?

Solid Edge
1

so i want to create a sketch for a revolve detail, but it keeps telling me this after i draw new lines to get rid of some other error which says that something is open somewhere…

so how do i even fix the “open” sketch in the 1st place to not get this “elements” error ?

and after all of those it just says “unable to compute topology information” or smth and crashes after some more random edits?

An image of the sketch would be helpful.

Happens if you have 3 or more elements for a profile joined to the same intersection. Typically, due to overlapping elements that occurs when the user Projects other geometry to the sketch and clicks the same geometry twice to get a duplicate. You can find it by hovering over the elements with the cursor and then looking at what QuickPick shows for elements.
