Design Intuition - 1.5.3

Gizmolab states, on their website, that design intuition is compatible with Leopard. In practice, just the opposite is true. You can load drawings created in 1.5.3 (running with Tiger) but once saved using Leopard, they will not load again. Emails to Gizmolab have gone unanswered.

This is niche software at it's most promising. Based on some good ideas, with a well thought-out user interface and excellent graphics, it is aimed nicely at its market.
The ease with which one can manipulate 3D images catches the imagination. And the bookcase-designing tutorial gets the feet even further off the ground. But then warning bells start to ring - have I got the information I need to make the bookcase? The answer is No. And the reason becomes clear when you start to exercise the package. It's based on lego-like building of rectangular and circular cylinders, and the only dimensions available are those for each cylinder itself. The system is very useful as far as it goes, but the trouble is that inter object dimensions are not apparent. So if you want to make a door with a centre rail for example, it's distance from either of the other rails is not recorded. This may not matter if you only want to get a 3D impression of what the door will look like, but it's not much good if you want to make the thing. The fatal flaw as I see it is the absence of a ruler and associated construction lines. If you want to see how it could be done, take a look at SketchUp. Unfortunately SketchUp is not right for serious woodworking, but then nor is Design Intuition - yet.
