Edit (Mar 2023):
This wish was originally for Vectorworks itself, and I would still love to have this kind of navigation built into Vectorworks, but where we could *really* do with it, for the sake of our own clients is VGX web views.
What I want is real-world navigation physics:
Awareness of solid objects, default mode should be that you can't walk through them.
Ability to walk up stairs
Ability to walk through doors/gates. Or, even better, VGX would parse the model for doors/gates and animate opening them when you walk through them.
Ability to climb through windows, as item above
Ability to jump/climb over objects
Gravity, jump over an object and land on the surface below etc.
When you click on first-person mode it should set you down softly on the nearest horizontal surface with a smooth animation.
The viewing height should remain consistent relative to the surface you're on.
And perhaps with a stepping motion rather than a smooth camera effect (with the option of smooth motion), or an option for third-person navigation (i.e. you can see your character in front of you)
We should be navigating VGX models like this:
Original post:
I'd like to be able to walk through a model like you can modern 3D game, with awareness of physics, such as gravity.
Graphisoft have attempted this in ArchiCAD, although it looks a little ropey:
