General Anim8or Forum / Re: Difficulty Extruding along Splines

To obtain better results, place the object you wish to extrude centered at the beginning (the "tip") of the spline.

Thanks Rudy!

That seems to have helped quite a bit.   Roughly the first 2/3rds of the pipe is coming out perfectly now -- right up to the point where the pipe heads vertically downwards.

After there, I'm getting a bit of a "twist" effect at various places along the pipe.   Any ideas what might be causing that?

Ross.

General Anim8or Forum / Difficulty Extruding along Splines
« on: August 27, 2009, 05:34:55 am »
Hi,
I'm new to the forum, but I've been using Anim8or on and off for about a year now.   I've hit a hurdle I just can't figure out though, so I'm seeking expert advice here! :)

I'm trying to get the Extrude along a Spline feature to work properly, but its producing some bizarre results for me currently.

What I'm trying to model is a piece of 'pipe' which includes a fair number of smoothly-curved bends in it, going both horizontally, and vertically.

Using the Spline tools I've got my pathway drawn (see attachment #309), with a mixture of straights and curves.   It follows the shape I'm after perfectly.

I then use the Curve Spline tool to make a separate, small, circle which I wish to extrude along that pathway in order to make the pipe.

I highlight the circle, choose Build>Extrude, then set the 'Axis' to 'Path' and click OK.   Once the dialogue closes, I select the pathway and I get the weirdest danged results (see attachment #310)!

Can anyone try to explain to me -- in laymans terms please -- what I'm doing wrong and what I need to pay greater attention to in order to get this feature to work?

Thanks in advance for any assistance!

Ross.
