Solid edge console application doest make lines

[andries41]

Hello,
I made the following code with visual basic 2003 to make curves in solid edge.
The problem is that the program doest draw anything in solid edge. Every variable i got, what is read from a text file, is used. The arrays for making the curves with the BSplinecurve2d.addbypoints method are also stored.
But nothing happens, only a part window gets opened.
Anyone knows why this is?

The code is a bit long so sorry if it is getting a bit too much.

Thanks in advance.

Okay i managed to make it draw my lines and curves, but the problem now is that my data is stored as meters. In solid eddge i will get really big lines and curves. Can i convert my data in visual basic to millimeters?
Also i wnat to edit my sketch, but i cant acces my sketch. And when i save th file, the lines and curves just disappear.
