Hi! I am looking for a LISP to replace 2D-blocks in a file (more than 1900 pcs of the same one block) with an Mview-block instead. Any ideas? 1900 thanks in advance!

What is a Mview block?

MVIEW block is multi view block. Only available in verticals like AutoCAD MEP. Basically the block has different views, from top, front, back, left and right. So when you create elevation view or section view, the software will use show appropriate view for that particular block.I don't use them frequently and long enough... so I don't know if that's possible.
