SMARTSEL
Select closed curve objects (circles, ellipses, splines and plines) as the boundaries and select objects inside them with WP, CP or EP options.
It also provides an option to make blocks based on above closed individual boundary selection and name the block from the content of a text object inside the boundary.
Objects in the final result are selected. You can execute any command such as "erase" on them.
INTRODUCTION
Valid boundary objects are closed LwPolyline, Circlec, Ellipse and Spline.
You can either select objects first or select objects at the prompt.
Command: SMARTSEL
Selecting mode [Wp/Cp/Ep] <Cp>:
Select "Wp" to use Wpolygon method to select objects inside all boundaries.
Select "Cp" to use Cpolygon methond to select objects inside and crossed with boundaries.
Select "Ep", simliar as Cp, but excludes objects outside the boundary and only touch at one point or overlap with the boundary.
If WP or Ep mode is selected, after the selection, it prompts:
Enter an option [Block Select] <Select>:
Select
Simply select objects with Ep mode.Block
If there is a text object in a boundary, the boundary object and all object selected will be converted to a block. Its insertion point is at center of the curve object.
EXAMPLE
3 enclosed green polylines on top of red circles. Blue lines are trimmed by green polylines.
To select 3 polylines as the boundaries, we can pick up one of them then use SelectSimilar command to select all of them.
3 different selection mode make different results.
WP only selects objects completely inside boundaries.
CP also selects anything touches the boundaries include most blue lines.
EP is simliar as CP, but excludes all blue lines because them are outside the boundary and only intersect the boundary with one end point.

NOTES
It doesn't check if Pline is self-intersected.
Ensure current layer is turned on and unlocked.
It doesn't work within a locked paperspace viewport.
Polyline with thickness may not be selected accurately in EP option when they are outside the boundary and touch at one point.
Select objects with Smartsel first, press Esc, then use ERASE -> REMOVE -> PREVIOUS to reverse the selection.
You can use QSELECT or SELECTSIMILAR command to select boundaries objects on same layer first then use SMARTSEL.
