You can use this code to create multiple clipping boundaries on IMAGE, PDF, DWF, and DGN UNDARLAY, external references (xrefs) and viewports. Supported clipping entities are lwpolyline, spline, splined polyline, circle and ellipse.

During selection set generation user is offered to separately select inward and outward directed clipping boundaries.

Create your viewport in layouts, define clipping boundaries, one or more and that's it. Ina layout you can add only one viewport, and create clipping entities, (polylines, circles, ellipse or splines) and after clipping main viewport will be multiplied-

You can also quickly generate viewports prepared with those polylines just by picking them using this tool:
