Change Block Base Point

Change Block Base Point



The program allows the user to change the position of the block base point for all references of a block definition in a drawing.


The program offers two commands:

CBP: Change Base Point

This command allows the user to change the position of the block base point whilst retaining the insertion point coordinates for all references of the selected block. Hence usually, the block components will be moved around the insertion point when the base point is changed.


CBPR: Change Base Point retain Reference position

This command also allows the user to alter the position of the block base point, but will retain the visual position of each reference of the selected block. That is, the position of the block reference geometry will remain unchanged, and the insertion point for each block reference will be repositioned.


The program will perform successfully with rotated & scaled block references, constructed in any UCS plane.


For a full description of the program, view Change Block Base Point at Lee Mac Programming.

    Lee's programs are always the best.  They fill in all the gaps AutoCAD should have done.
