I find a very strange question. After I called the function bs3_curve_set_closed, the start point and end point of the bs3_curve is still different. Who know how to use this function?

I have a couple of comments:
1) this is a fairly low level function. what are you trying to do? The higher level we can discuss things at the more likely it is to be useful.
2) The form of a bs3 is more of a topological notion and less of a geometric one. If memory serves, the form is just set by a flag in the bs3 surface. Changing the form probably doesn't change the geometry of the curve at all.
hopes this helps.

I want to construct a closed curve. May be I should construct myself.
I have another question about the bs3_curve interface.
I create a spline by the bs3_curve_make_ellip and the input curve is a circle. However, When I call the bs3_coinc_type function, and I get the result bs3_not_conic. What's the reason for this result?
