Assembly3 ConstraintArcLineTangent

Description
The command builds a link between two objects of an assembly. The selected elements of each object or more precisely their implicit coordinate systems (ICS) are used to position one object to another.

Since I couldn't get this tool working here's just the statement of the tool tip: Add an "Arc line tangent" constraint to make a line tangent to an arc at the start or end point of the arc.

Usage

 * 1) Place two objects into an assembly
 * 2) Select an arc element of one object
 * 3) Select a line element of the second object
 * 4) Press the  button.

Depending on the order of the selected lines following errors appear: Constraint "ArcLineTangent" requires the 1st element to be a circular edge Constraint "ArcLineTangent" requires the 1st element to be an arc edge
