The polygon editor’s Move Tool Group consists of the Move Element Tool, the Move Normal Tool, and the Slide Element tool (edge mode only). Design 3D controls the movement of elements (polygons, edges, vertices) using different ‘constraint’ modes. These are active grids, guides, geometry ‘normals’ and sliding. The listing below shows how the 3 tools in the Move Tool Group operate relative to these constraints in order to precisely manipulate geometry. Movement for any element (polygon, edge, vertex) is; 1. Free form, parallel to the active grid (default behavior) 2. Along a standard axis; 3. Perpendicular to the active grid;
