This will work on wals and things connected in a linear form too. "Tab" selects the "chain" of lines connected to the segment you are hovering over. You can however pick them all at one time by pressing the "tab" button as you hover over one of the lines. On another note when you use the rectangle tool in Revit it does draw 4 seperate line segments. If you need 2 rectangle objects like this side by side with a co incident edge, you will need to draw the 2 itmes seperatly in Revit. You would end up with overlapping lines at the co-incident edge, and you would have created the "short circuit" with the line for the edge where the 2 rectangles are co incident.

If segments are overhanging at the corners, not completly closed, have overlapping lines, or have a "short circuit" in the sketch, you will get an error message like you are describing.Ģ rectangles placed next to each other with a co incident edge would create 2 conditions for this error. When sketching the shape for an object most of the time Revit wants a closed loop. Based on your description of the shape you were drawing when you recieved the error, I think the problem is, you are not creating what Revit would define as a "closed loop sketch".
