extrusion

[leach]

im trying to extrude a simple NURBS circle along a closed curve which i extracted from a nurbs model. sounds simple enough, but when i extrude it, the result is a huge random tube throughout my scene.

ive tried doing a simple test of extruding a circle along another circle which i scaled in the Y, but this produces a squashed torus which is rotated by 90 degrees to the path it was meant to follow.

ive tried different variations of rotation, but all to no avail, and im using soft 3.9.

can anyone shed some light on this...if youv'e managed to understand what im talking about that is!!

cheers

Place your circle in the Front view at 0,0,0. Soft uses this position to be know where to place circle on curve. Use Preferences/Modeling Relations to make extrusion update if you change circle or curve.

When you extrude, be sure you select "Along Curve" as the direction.

Hope this helps,

it worked!!

thanks for that, i never would have thought it needed to be at the origin to work.

cheers

FYI:
To get your object's center at exactly the 0,0,0 origin you can use:
Modeling- Effects/Freeze.

If you know your object center is in the correct location and want to move the object to the origin, you can do this:
In the transformations on the right side of the interface (Scale Rotate and Translate).
1. Click on one of the triangles at the top/left of the Translate buttons.
2. Select Reset.
3. This will make any transformation (Scale, Rotate or Translate) go back to default values. In this case, your object's position will again be
0,0,0.

Hope this helps,
