im asigning a tangent relation to a 3d line and spline. the p[roblem i am having is that it asigns this relation to the closes tangent that is possible. is there a way to reverses the tangent or asign a direction to the tangent.
what im drawing in vb is 2 3d lines with a spline inbetween. this spline has only its 2 end points. and it is tangent on both sides. if you draw this manualy you will find out what my problem is placing these tangent relationships. the second tangent reverses down the line. i could add extra points and then delete them after. or i could draw all the segments in a strait line and move them after.anyone else have any ideas.
