These are templates for the PolyMesh editor. They belong in a folder within your "plugins" folder, called "PolyMeshTemplates" (no spaces). You will need the PolyMesh Plugin to use these; the plugin is available by going to Tools -> Scripts and Plugins Manager and clicking on the "Install" tab.
After you put the templates in the correct folder, you can double-click the PolyMesh Editor icon in the AoI toolbar and choose which one of them to draw when you create an object with the PolyMesh tool.
Uploaders, please upload as a ZIP file to save space. ZIP gives really good compression ratios with these files.
Here are some typical UV spheres for use in the PME. Should be helpful if you're doing tutorials from other software that require you to start with a Polymesh sphere. The number next to each template name is the number of rings/segments in the sphere. Included are 8, 16, 32, and 64.
Sort of a weird set , but helpful. A quick torus in PME, a rounded cube done the proper way, and a monkey. The monkey is Suzanne from the Blender distribution, but she's solid in this case, so you can apply and test materials (for example, subsurface scattering).
Two objects: A 6-sided elongated span, and a plane, both greebled using Blender's Discombobulator script (in the "mesh" category) and exported as Wavefront .obj.
These two objects are complex and will probably be slow to manipulate on low-end computers, or computers with low-end graphics cards. You can see them at work if you like...
