A tool for GMod10 which takes the drudgery out of welding large contraptions and forts.

Rather than manually welding everything, you can simply select the props that you want welded (this can be done with a single click using auto-select), then right click to perform a smart-weld using the chosen settings.

Props are automatically welded to their nearest neighbours, and extra stability welds can be added automatically too.

A video of the smart-welder version 1 in action can be seen here:

By the way, the STool is packaged as a GMod 10 addon, so unzip the file into your "garrysmod/addons" directory.
