3D models
You can resize 3D models separately on axes.
To do this, enter new values into X, Y, Z boxes during 3D model editing. If the box is marked, change of any size leads to proportional change of other sizes, thus model proportions are not broken.
3D model height above the ground is displayed and can be changed in the 3D H box.
In multilevel projects, the height are calculated relative to base height of a layer to which the 3D model belongs.
If the Shadow box is checked and the Shadow calculation is enabled and 3D models are taken into account in calculating shadows, then the editing 3D model will be considered as an obstacle during calculating shadows.
Calculating shadows from complex 3D models  very resource  intensive operation which can take a lot of time.

The button allows to open the 3D Models window with edited 3D model loaded in it.
In the Speed box you can specify speed of moving 3D model, in meters (foot) per second. Model with specified nonzero speed will move with this speed along a specified direction when modeling exposure time, Rolling Shutter, interlace distortions and creation of animated images. To set speed to 3D model you should enter a nonzero value in the Speed box during the placement or editing 3D models.
The length of the velocity vector of a 3D model in the normal state is inversely proportional to the frame rate of the active camera. Thus we can see how many times the moving 3D model gets into the frame of the active camera.
