Hi, I'm using Archicad 28. My TAB key isn't working correctly. When I press it, it's supposed to help me select overlapping elements, but instead, it's changing their position or angle. My Quick Selection is enabled. Any idea why this is happening? Thank you, Eddy

Hi, I have a problem with the shadow diagram study in plan.I want to show both the existing building shadows and the proposed building shadows on the same plan, but the elements I plan to demolish don’t cast shadows.Can you suggest why this happens and also make a video show...
