Google (who recently bought SketchUp) have split it into two products.
There is now the free version ‘Google SketchUp‘, and SketchUp Pro.
The more important part of the news release, as far as I’m concerned, is the 3D Warehouse, a user-contributed collection of SU components – essentially a direct competitor to my SketchUp Components Collection.
I’m glad there is now a free version, but of course have some reservation over the launch of the 3D Warehouse.
This is the first time that Google has directly affect me personally. (Chances are that the SCC will suffer)
