I am using sweep two rails, and getting the error message "Unable to sweep - two shapes are too close together"
Details: The shape I am trying to create is like the roof of a cave. Arched overhead, with changing arches specified by cross section curves, tapering down to a point at each end.
The rails are mirror images of each other, about 360 mm from end to end. I have cross-section curves defined about every 2 mm. (Generated by mathematics elsewhere.)
I select the two rails, then for cross section curves I select the points at each end and the cross section curves. I get "Unable to sweep - two shapes are too close together".
What are the conditions that produce this error message?
I could stretch the whole thing out by a factor of 10,. So that the cross section curves are 20 mm apart. But I'd like to know if this might help, before I try it.
Hi David- please post, or send me, the curves you are using.
False alarm: I had to look very closely, but it turned out that some of the cross-section curves were duplicates! So it is not surprising that this produced an error message.
Thanks Pascal for beginning to look at this. And my apolgoes for the false alarm.
No problem, I'm glad it's sorted out - thanks for the update.
