Well, to the best of my knowledge... we still haven't earned a place to post Mvparts specific to ABS, but I just created a rather simplified trench drain approx 6x24. I think I'll post it to the customer files or AEC content group. -- I'll need feedback on the pro's and con's of how I created it... too detailed? Not detailed enough? Did I even create it the right way? it seems to insert accurately... this is my first "from scratch" mvpart. So any advice will help in my future parts. I'm not sure that I completely understood the process and so I'm sorta winging it.
