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.
