All reference points are called "Inference Points"
- On Edge Points
- Mid Points
- Press wheel down to orbit
- Press wheel down + shift key to pan
Hover cursors over any inference points to anchor your centering navigation around that inference point.
Any line one a shape can drag both ends, shaping ridges
Blue is the Y axis
Red and green is the X and Z axis
Any edges made across coplanar surfaces can be erased to create or recreate larger surfaces, or "healing" the surface
Sketchup will infer from any inference point, such as a midpoint, of any relevant point along the line, hover over an adjacent or orthogonal line.
