A "mammoth tusk" created with extrude path + scaling.

This plugin acts similarly to the "Extrude Path" function in AC3D, but allows you to scale the result from the beginning to the end of the path.

AC3D versions prior to version 6 have not been tested with this script.

History

2004/04/24 : Posted Linux port.

Installation

Copy the extpath_scale.tcl and extpath_scale.p files to your AC3D plugins folder (for example, if using Windows, C:\Program Files\AC3D\plugin) and (re)start AC3D.

You will find the "Extrude along path with scaling..." menu item under the "Tools" menu.

Usage

Behaves similarly to the built-in Extrude Path command, but provides a window for specifying the amount to scale the results of a path extrusion.

See the AC3D manual for usage of Extrude Along Path.

With this plugin, first select the "profile" object, then hold down the shift key and select the "path" object (similar to the way the original Extrude Along Path works).

In the pop-up window, specify how much scaling you would like to apply to the extrusion. This number is expressed as a percentage of the profile shape. So, for example, specifying "25" means that the profile will be scaled down to 25% of its original size from the beginning to the end of the path, while "150" means the profile will grow by 150% along the length of the path.

Naturally, this depends on the order of the vertices in the path object.

Known issues

When an "Undo" is performed, you may have to re-select the profile and path objects. This is because the order of the selection is not retained across an Undo.
