Trim Outside Area (Crop)

This tool automatically trims and removes all objects that are outside of a　selected closed polyline boundary, leaving only the objects inside.

Smart Filtering

It specifically preserves blocks, text, and dimension objects that overlap the boundary (they are not trimmed or　deleted).

Caution

Be aware that this command　deletes all other objects outside the　selected area immediately.

All objects outside this boundary are automatically　deleted, while objects inside (and overlapping special objects) are kept.

1. 1.Type atr in the command line and press Enter.
2. 2.Select the Closed Polyline that defines your boundary.
