Summary

Unable to control rotation center in version 6.6025.1.1.

Solution

In version 6026 a few changes have been made in the 3D-rotate action. As a result, users couldn't effectively control the center of rotation. To deal with this issue we have added the DynamicRotFlag property in vdDocument.GlobalRenderProperties. By setting this flag to AroundViewCenter you’ll have the same behavior as before the chages happened.

DynamicRotFlag can take the following values.

Auto:
Rotate-3d action uses the following criteria : if an object exists behind the cursor then the clicked point acts as the rotation base point. else if the mid point of the model bounding box is inside the view it is used as the rotation base point else the center of the view is used as the rotation base point( the center's Z value is set as the bounding box mid point Z value).
AroundViewCenter:
Rotate-3d action rotates the model around the center of the View (the center's Z value is set as the bounding box mid point Z value).
Default:
The default flag used by the programm.Same with Auto.
