&CHTOL
Provides for the chaining of objects which do not intersect or do not have end points which are coincident. The default value for this GPA is 0.0 which means that the objects must intersect or have end points which are coincident.
You can assign a value of up to 100 which means that the distance between the two objects may be up to 100 units. Once the tolerance has been established, selection is made per the &CHAIN GPA.
