any tips?

William, Just answered your question for an assembly, and suggested a Shadow Analysis. For something as simple as a block or sphere, I would, however, create a Sketch on an appropriate plane, and use the Create an entity from an edge icon to pick silhouette geometry. After you finish the Sketch, you can do Edit/Fill if you want to create a Surface representing the shadow. Afterward, you can hide the Surface, as necessary. David

thanks David, your create sketch worked well, especially because i did edit>fill, which i wasn't doing before. Shadow analyisis sort of works for my big assemblies but I haven't quite figured out what the "quality" "number" and "step" plot samples are, except that the answer varies when those parameters vary.
