Handy tool for polygonal modeling– “Extrude Along Spline”

Extrude Along Spline is a very useful tool for creating organic (and multiple) extrusions of polygons in 3 dimensions based upon the shape of a 2 dimensional spline.

It is quite simple to use.

-Simply take your 3D geometry, and from an orthogonal view port, create your 2D spline that represents the direction and length of the extrusion.
-On the 3D geometry, at the sub object polygon level, select the polygons you would like to extrude in the shape of the spline.
-Next, select “extrude along spline” from the modify command panel (it is recommended that you use the settings sub menu so you can have greater control over the extrusion.

As you will see you can control the number of segments, taper, twist and curvature.

  1. HOW I MAKE TAIL

  2. does this work with vanilla meshes?

  3. how I can animate the extrusion made in this way?

  4. Hi there, I found your blog by the use of Google whilst searching for
    a related topic, your site came up, it seems to
    be great. I have bookmarked it in my google bookmarks.

    Hi there, just changed into aware of your weblog thru Google, and located that it is truly informative.
    I am gonna be careful for brussels. I’ll be grateful if you continue this in future. Many other people might be benefited from your writing. Cheers!
