This has evolved over many years so it’s not quite a fair comparison against a new offering like form The extensions community for SketchUp did not happen overnight. This is very important as these models can be used in advanced modeling operations and 3D printing where Sketchup models often fail. We should note that a major difference that you did not discuss is the quality of the underlying geometry. In addition to real-time visualization, the animated shadows can be exported as an animation (as a QuickTime of AVI file).
FORMZ PRICE FULL
FORMZ PRICE PRO
I'm not so sure the same can be said for FormZ Free in it's current guise. Sketchup Pro and FormZ Jr have very similar pricing but FormZ Jr far excels Sketchup Pro's capabilities so it's a real pity that FormZ Free can't compete on a more equal footing with Sketchup Make. Sketchup Make not only fulfils a great need in the hobbyist/education sector, it provides an uncrippled experience that helps convert Pro trialists into fully fledged customers. Sketchup Make can only be used for non commercial projects but in most other ways (other than IO capabilities and the lack of Layout) it's uncrippled and provides the same rich feature set of the pro product. Trimble have been very smart in their licensing terms too.

Community is the real secret of Sketchup's success (not that the product used to be owned by Google). For FormZ Free to succeed it needs to be a product that a passionate community can support. I can't see it being an attractive option for existing Sketchup Make users, it's no real use for rapid prototyping and it lacks the tools to make it a useful walkthrough presentation tool for FormZ Pro/Jr users. So all in all, I'm left with the impression the FormZ Free is caught between 'pillar and post'.
