We have discovered a few things about blocks and SW2007. 1. It appears that you can no longer align them. In SW2006, you Ctrl select two or more, and a RMB menu has the Align option. Not now. 2. The Insert Block icon was removed from the Annotations toolbar - I had to put it back from the Blocks toolbar. 3. I had a macro that would not recognize the block any more. I was looking for a type 93 (BlockInstance), and the block is now recognized as a type 114 (SketchBlockInstance). I also had to use Set swSUBSKETCHINST = SelMgr.GetSelectedObject6(i, -1), rather than Set swBlockInst = SelMgr.GetSelectedObject4(i). There's obviously been some changes in how SW handles blocks - I presume it's the result of incorporating the sketch blocks. More investigation to follow as I have a chance. WT
