  • So, you have a situation where you have a particular block in your drawing, and you want to change the block and have your drawing updated with that new block. If you don’t have that block already defined in your drawing, or you can purge it out of the drawing, then you don’t need to…

  • From a customer: “Now that I freelance for several different clients, I run into some issues with AutoList. I have to change a couple of the Top Five FIGs each time I bounce between clients projects, as I only stocklist as they request piping to allow for any building or coordination changes. This causes issues…

  • If you want to have only one branch line ID for an entire branch line, but are worried that AutoList will absorb other fittings into that branch line, or will miss certain sprinkler heads because of the default way it does things, then this is how to set things up properly. The part I mention…

  • So, my co-worker (who shall remain nameless) sent me an annotated drawing with notes on how to properly model trapeze hangers for coordination. The notes were written as individual lines of text. This annoys me: I like working with MTEXT so much more. MTEXT allows for formatting, fonts, underlining, numbering and more. I thought I…
