I've made a cross-section of a railroad track, and extruded it along a curved path to create a railroad line.  How do make it so the extrusion is denser so the curves are smoother?

[Indian8or]

Why not try subdividing it by 1.

[Gregory]

Because that will in addition to increasing the number of segments perpendicular to the the path, my goal, increase the number along the path, creating a lot of unnecessary polys.

[Indian8or]

Then, do one thing while drawing the path to extrude, include more segments in the path itself i.e.  the path itself should contain more segments.

[Gregory]

That is a useful suggestin for the future.  This path is already drawn and I cannot duplicate it.  Even with fewer points the path segements are the same space apart. 

How can I have anim8or make more cuts per segment?

[Indian8or]

That will again increase the poly count.  Try smoothing the angle.

[Gregory]

Look at the attachment I posted.  Where the black lines I drew intersect the track, I want anim8or to put extra cuts.  That's it.

[Indian8or]

Exactly man, for that you need to draw the path again and whenever there is a bend in the path include more vertices close enough to get the required smoothness and extrasegments.

Of course to the best of my knowledge, this should work.

[Gregory]

As I said before I cannot redraw the path.

[kreator]

Go into point mode select the knife tool and cut where you want intersections.

[Gregory]

That doesn't work on the path, only the model.

Select the "Path Edit" tool to edit any part of your path. If you doubleclick a segment between points, you can edit the number of "subsegments", if you doubleclick a point, you can edit its properties...

It's all in the manual btw: http://www.anim8or.com/manual/3_object_editor.html#splines
