I've added a module for Site Plan info to the Modules folder (in 3 Resources). It contains all the elements for contours, boundaries, notes, etc. I did not include separate note stuff for the 120 & 240 Note layers, but you'll probably live. N.B.: 8.1 only!
AC8.1 improves Composites substantially. A summary.
Starting Monday, Dec. 8, we will be moving to ArchiCAD 8.1 and PlotMaker 3.1. This is a relatively minor feature update, with noticeable performance and interface improvements. No, it's not perfect, but it is better. Unlike the 7 to 8 update, we will move current projects over.
