View Full Version : Drawing Curve Problem (Rhino 3)

07 July 2004, 11:36 AM
Hi, I have a problem drawing curves.

I want to draw the curve of the roof of the car. As show in the picture.
But, i dont understand how it works. If you place the points on the line of the roof, it bends inward and not follow the line.

While in Photoshop, this can be done easily in photoshop with control points. Which I've created in the picture.

So can some one help me out with this problem?
How can drawing a curve be that hard? I dont understand!
I cannot control the curvature and direction of the curve...
I want to know a flexible and accurate way to do this.

I have much difficulty learning rhino, please help me out. :)

You have 2 choices:

1) just move the points around to line up the B-Spline to your drawing.

2) Draw the curve using Interpolate Points (2nd choice in the draw curve flyout button). The curve will flow through your points.
