Win32 and 64, English

Lee Mac Programming
Change the base point position for a selected block.

General Usage Instructions

Upon issuing one of the above commands at the Autodesk® AutoCAD® command-line, the program will prompt the user to select a block for which to change the base point position. Following a valid selection, the user is then prompted to specify a new position for the base point, relative to the selected block reference. The block definition (and block reference, depending on the command used) will then be modified to reflect the new position of the block base point. If the selected block is attributed, an ATTSYNC operation will also be performed to ensure all attributes are in the correct positions relative to the new base point. Finally, the active viewport is regenerated to reflect the changes throughout all references of the block. Please note: The drawing will need to be regenerated if the UNDO command is used to revert the operations performed by this program.
