- Axonometric / Perspective view (if perspective your camera may be looking in the wrong direction - change from one to the other and...)
- Zoom Extents - does anything appear (and check in plan view that when you Zoom Extents that there is nothing a long distance away from your model - you might have to do this for each storey)
- If in perspective mode and camera appears to be pointing in the right direction check the camera and target heights (check 3D Projection Settings)
Possible solution:
- Place a camera and make sure camera / target heights are appropriate. Select camera then go to 3D window.
It seems like the 3D window doesn't open.
And if I change the engine to inside engine (not using the 3D open GL) the 3D appears, but very slow and with poor graphics.
in particular the video card requirement? (Laptop should have a dedicated graphics card, not an onboard chip that shares main memory which is common in low-end laptops.)
