SimuSEM Tip: Rotating Sample
When using the rotation widget in the upper right corner, does the sample seem to rotate around a point far away from the center? Fix, by telling Blender to use a selected object as the center of rotation. First, select a small enough shape in the sample. Then press the period key in the numpad on a PC keyboard. Blender calls this Orbit Around Selection.
If you end up with a large shape as the rotation pivot and have trouble rotating the 3d view, just select a relatively small object and press the numpad (.) key. Look here or in the Blender manual for more information.
