Polyhedra
=========
Plugin to draw the five Platonic solids (Tetrahedron, Cube, Octahedron, Dodecahedron and Icosahedron), size specified by either radius or side of solid.

Install the plugin in the usual way (see notes at [Sketchup Knowledge Centre - Installing Ruby Plugins](http://help.sketchup.com/en/article/38583 "Sketchup Knowledge Centre - Installing Ruby Plugins")).

After installation, you should find a new Draw menu item _Polyhedra_, with a sub-menu for each shape.

At the first prompt, choose whether to specify the size by length of one side, or by the radius (of a circumscribed sphere).

At the second prompt, enter any valid length, in any valid units, for either Side or Radius as previously chosen, press OK, and the solid will be drawn as an un-named Group at the origin. You will get an error message if your entry cannot be parsed as a length by Sketchup.

To edit the solid, right click on it and choose _Edit <name of solid>_. This will prompt for a new value for the size. 

To change to sizing it by radius rather than side, or vice versa, delete the solid and draw it again.
