Arc is always 2D - but you can draw it in any workplane - so first define a UCS in 3D and then draw an arc in it. The proposed way of using 3DROTATE to rotate an existing "flat" arc also works.

One option using 2012 is to use the LOFT command. Another option might be to Extrude with a taper. A third approach might involve using the Slice command and Surface option. Many ways to skin a cat.
LOFT with PATH option definitely works. See image in post below. I used two profiles (one for each end). Edited by John Connor - 18.May.2011 at 15:11 |

Hi all, 'm not completely new to 3D but came across one thing that I cannot find answer to. How do you actually draw a 3D arc? I need to model a 3D ramp to basement that consist of straight line, an arc and a straight line again (L-shaped ramp). I would normally extrude or sweep profile along a path. But I'm not able to draw the arc. I tried to draw a 2D arc and rotate it, but that doesn't really do the job. I'm using 2006 but have access to 2012 too Any help much appreciated. Thanks |
