What im going to do now i know i can is create a 3d draping thin canvas, sloping in 3 directions to cover a part of my building. I know revit cannot do this, im only guessing archicad cannot do this, so my solution was to import a solid from architectural desktop.
ArchiCAD can do it, if you know how to do it in GDL. Or, as was advised already, check GDL Toolbox - my personal favourite for all things canvassy - at http://www.gdltoolbox.com
One niggling thing i have with archicad is the maneuverability. Is there a fast way to pan and to zoom or do i have to keep selecting the option with the mouse? I like to work with the keyboard and mouse at the same time, its faster.. ?
In 8.x you have the zooming and panning as you are used to (scroll to zoom, press the wheel and pan). If your mouse is programmable, you can assign the wheel functions to the zooming keyboard shortucts already posted.
IMHO the upgrde to 8 (meaning 8.1 as the 8 to 8.1 upgrade is free) will enhance your working a lot; first, you get the Booleans that you are used to, second you get the zooming an panning, third you get the Navigator and VASTLY improved PlotMaker.
ArchiCAD since 4.55 ... 1995
