Two more of my plugins are now published.
The first creates all faces that can be created from the edges, either in the current drawing context or inside a selected group or component. This can be useful when importing wireframe models only consisting of lines or for creating the cut faces for a section cut.http://extensions.sketchup.com/en/content/eneroth-face-creator
The second one was created for my most recent school project and moves all vertices in the selected group/component to make the old x coordinate represent the radius and the old y the angle in a cylindrical coordinate system. I wrote this script to easier draw a spirally building and be able to use the native tools, such as the scale tool, more easily to create the shape I wanted.http://extensions.sketchup.com/en/content/eneroth-spherical-coordinates
