About Using AutoCAD Object Snaps With Alignment Objects

You can use AutoCAD object snaps (OSNAPs) with the alignment object. Although there are differences, alignment OSNAPs function in a manner consistent with OSNAPs to AutoCAD lines, curves, and polylines.

Node snaps apply to all pass-through points and all points of intersection.

In the following tables, Yes indicates that OSNAPs do apply; No indicates that OSNAPs do not apply.

OSNAPs That Apply to Line Segments

Use OSNAPs with some alignment components. Alignment line components can have solved and unsolved segments, depending on whether they are fixed, free, or floating.

Line Segments	Solved Segments	Unsolved Segments
Endpoint	Yes	No
Midpoint	Yes	No
Center	Yes	No
Node	Yes	No (Exception: Node does apply to visible pass-through points.)
Quadrant	Yes	No
Intersection	Yes	No
Extension	Yes	No
Insertion	Yes	No
Perpendicular	Yes	No
Tangent	Yes	No
Nearest	Yes	No
Apparent Intersection	Yes	No
Parallel	Yes	No

OSNAPs That Apply to Curve Segments

Use OSNAPs with some curve segments. Curves can have solved or unsolved segments depending on whether they are fixed, free, or floating curves.

Curve Segments	Solved Segments	Unsolved Segments
Endpoint	Yes	No
Midpoint	Yes	No
Center	Yes	No
Node	Yes	No (Exception: Node does apply to visible pass-through points.)
Quadrant	No	No
Intersection	Yes	No
Extension	Yes	No
Insertion	Yes	No
Perpendicular	Yes	No
Tangent	Yes	No
Nearest	Yes	No
Apparent Intersection	Yes	No
Parallel	Yes	No

OSNAPs That Apply to Spiral Segments

Spiral Segments	Solved Segment	Unsolved Segments
Endpoint	Yes	No
Midpoint	Yes	No
Center	Yes	No
Node	Yes	No
Quadrant	No	No
Intersection	Yes	No
Extension	Yes	No
Insertion	Yes	No
Perpendicular	Yes	No
Tangent	Yes	No
Nearest	Yes	No
Apparent Intersection	Yes	No
Parallel	Yes	No
