Description

Given a base selection of surfaces, selects all surfaces connected via edges. Sort of a "flood select" for surfaces.

Installation

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

You will find the "Select connected surfaces" menu item under the "Tools" menu.

Usage

To use, select one or more surfaces then perform a Tools -> Select Connected Surfaces.

Example

I've imported a Poser model for this example. The model was imported with no materials, and is fairly detailed. I want to be able to separate the main body from the eyeballs/eyelashes in this example. Without this plugin, this would be a painstaking session of selecting surfaces, cutting them away, hiding them, etc. until I had all of the surfaces separated as desired.

Of course, the plugin's usefulness is not limited to working with imported geometry, but this provides a good example.

Step 1: Select a surface

I've selected a surface on the character's face.

Step 2: Perform a Tools -> Select connected surfaces

All of the surfaces except the eyeballs/eyelashes (which are not connected to the main body) were selected here.

NOTE: On very large objects, you may see a significant slowdown due to the method of edge identification used in AC3D. The model in this example has nearly 30,000 polygons, and my machine took some time to gather the edges for this operation.
