How to update drawing blocks with an updated version from a DWG file?

A - answer You want to update a block or blocks in a drawing (or in multiple drawings) with a new modified version. You can use the free LISP utility by CAD Studio - BLKREDEF.LSP (see www.cadstudio.cz/download).

First save the edited block to a separate DWG file (using WBLOCK). In the target drawing first load (APPLOAD) the BlkRedef utility and use the BLKREDEF command to update (refresh) the blocks of a given name. The BlkRedef command with the parameter blockname can be used even in scripts to batch update multiple drawings at once (use any batch processor - like ScriptPro or ScrGen).

In your script, use e.g.:

(load "blkredef.lsp")
BlkRedef MYBLOCK1
BlkRedef MYBLOCK2
BlkRedef MYBLOCK3
save
quit
(the myblock1.dwg, myblock2.dwg and myblock3.dwg files must be in the AutoCAD search path)

You can also uncomment the line with blkredeflayswitch in the LISP code to sort updated blocks in specific layers - just set the pairs blockname-layername.
