Strange problem, maybe a bug? When I want to put a dimension, ordinary linear ones, I put my nodes without problem but when double clicking the workarea to get the hammer, nothing happends. But if I thereafter open another program or window in the computer, when I return to Archicad, the hammer is there and I can complete the dimension. Quite frustrating to say the least. Is it a bug or is it possible to say if I'm doing anything wrong. I have Archicad 16 for 32 bit Window 7.
