Stella Tutorial: Replacing polyhedra in a compound

Using Great Stella or Stella4D, here's a way to replace each polyhedron within a compound with a new model, thus making a brand new compound. The steps are as follows, or see the video below.

• Use "Poly→Keep One Part of Compound" (or Ctrl+K) to separate out one part of a compound
• Put it in a memory slot ("Edit→Put in Memory" or type "m1")
• Do whatever editing you want (e.g. augment or stellate the polyhedron)
• Add the result to the unedited item in memory ("Edit→Add/Blend from Memory")
• Select a face of the original unedited part
• Put this new model in a memory slot
• Re-open the compound you started with
• Augment this model using the item in memory ("Poly→Augment Polyhedron" or hit "a") and select to extract from all faces of the same type. You should also select Inherit colors from augmented faces to ensure your compound has the same colours as the original.

For the specific case in the video, a shorter way would simply be to augment all faces of the compound directly. However the method above allows for more general substitutions, such as replacing an icosahedron in a compound of icosahedra with any of its stellations.
