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