Hello,

       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?

      Thank you!!!

Hi,

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.

Thank you!

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?
