Andrew & Rob,
Thanks for the feedback. It looks like the symbol is based loosely on the Premier PSD-TL60 (72 & 84) https://www.premiermounts.com/product/psd-tl60/ so a pop-up or option dialog box with the real-world standards of 60", 72" and 84" would match those, and then a custom option so that can be , well, customized - which would be nice, because our shop just happened (literally) to have 108" custom cut poles that fit the bases - and that completely saved my bacon on this project.
I also attached the bracket adapter, which would line up with the center of the VESA pattern on the back of the monitors. I used to rep for Premier a few years back - thinking maybe I should contact them and have them work with you to build a library set of their products . . .
BTW, I am a long-time AutoCAD user (mostly self-taught, though), and my company just purchased Vectorworks for our team. I really like the tool sets in Spotlight, and am learning how to use them efficiently. Just the fact that this is so quick and easy to place into a trade-show or event drawing, and then alter as our clients make budget changes is a real time and aggravation saver. Same with the projection screen and LED wall tools.
Thanks again!
