On Land

Environment Information
At Rill Architects we run ArchiCAD on macOS. If you work at Rill, this is your stuff. If you don't, but you work in ArchiCAD, you may find something interesting. Anybody else, I don't know.

Some are redundant. I will probably think of more.

• Use the 'Working Dims Plan' Layer combination.
• Option+click on existing strings to maintain witness line justification as you move in.
• To add one string's ticks to another, select the string to keep and Cmd+click on the string with the points to add.
• Use the arbitrary angle setting when dimensioning walls, for auto-orientation.
• Use the 'place, rotate, drop' construction method with the CL object.
• To graphically justify a group of witness lines: Select the ticks. With the dimension tool, click on the segment and drag it to the desired justification point. Useful for backing up a few witness lines where the plan is very near.
• When you select a tick, the element the tick is connected to will briefly show as selected. To maintain this effect long enough to actually observe it, hold the mouse button down on the tick.
• Ticks can accumulate at a single point. If you try to delete a tick and it stays put, keep trying.
