BREPLACE — Replace Blocks

Replaces the selected block references with another block.

Replaces the selected block references with another block of the drawing, like AutoCAD BREPLACE.

Usage

Enter BREPLACE (or select the references first) and select the references to replace; press Enter.

Select block references to replace:

Enter the name of the block that replaces them (? lists those in the drawing).

Enter name of replacement block or [?]:

Each reference keeps its insertion point, scales, rotation and layer. Its attributes are rebuilt from the definitions of the new block: those with the same tag keep their value and the rest take the default one.
A reference of a dynamic block becomes a plain reference of the new block.
In AutoCAD 2027, BREPLACE opens the Blocks palette (and asks to sign in to Autodesk): it cannot be checked in its console and has a unit test. To change every reference of a block, use BLOCKREPLACE.
