Hello everyone 
I have these dynamic blocks in my drawing with several parameters and attributes. These dynamic blocks needs to be replaced with a more "efficient" one. Blockreplace will replace the old blocks but parameters and all properties are reset. Redefining these blocks is not an option either.
I need to extract all properties including Geometry (position x, y, z), Misc, General, Custom and Attributes into Excel make changes to any properties and apply it to the new blocks.
Autocad's dataextraction works perfect but how can I put the data back (including property modifications) into the new blocks?
PLease help! thanks in advance
