Summary: Draw arcs in 3D of which the grips are editable and moving one grip to a new location in plan or height will not move the whole arc without having to alter the current ucs.

Description: Draw arcs in 3D of which the grips are editable and moving one grip to a new location in plan or height will not move the whole arc without having to alter the current ucs.

How Used: When drawing 3D linework topographical surveys the ability to be able to draw an editable 3darc is essential. We currently have a lisp routine which sets the ucs based upon 3 points with different z values selected to and then draws an arc. BUT unless you remain on the ucs that a non flat arc is drawn on there is no way to edit the this using the grips without unwantingly moving the whole entity.

Feature Affinity: 3D
