Object Mode and Edit Mode
Creates edges and operationally faces by snapping to mesh elements. When moving the cursor close to a face, edge or vertex, the cursor is snapped to the highlighted element. It can also be snapped to center or perpendicular of an edge. After selecting the first point you can specify the length of the line by typing a value and confirming with Return.
- Axis Constrain X, Y, Z
Constraint the cursor movement on the X, Y, or Z axis.
- Edge Constrain Shift

- Create Faces
A face is created when:
It detects the drawing of a closed segment.
The last vertex of the segment binds to an edge that connects another vertex of the segment.
It detects an isolated edge loop.
Redrawn existing edges and the vertex of the last segment binds to an edge that connects another vertex of the segment.
Extends Blender Snap controls.
