Force cursor tangent to the selected edge.

 

 

The edge nearest the pickbox will be selected. The pick-box must be located over an entity or construction line.

 

Once selected, all cursor movement will be constrained to the tangent defined by the selected edge. Points can now be selected anywhere along this tangent.

 

Once a point is selected, tangent snap is automatically cancelled. Tangent snap can be cancelled at any time by pressing the escape key (Esc) or right click the mouse.

 

To select points at even spacing along the tangent line, tangent snap can be used in conjunction with any of:
