I am new to CA Suites 2015 and have managed to produce a floor plan. The automatic dimessions seem fine. But I have some items located throughout the plan where I really want to add location Dimension lines. An example is a light location. I want to add dimmension lines from a wall to the lights center. Ever Dimension tool I try just draw a line and then dissapears on button release. I can draw dimensions between walls and they stay. Thanks for your help.
