I am using Sketchup for Web. I am modeling a wall built out of 2x4 lumber. For instance, I am trying to make 2 boards touching perpendicularly to form a T, and I want to be able to later move the leg of the T along the length of the arm of the T to a new position.
First I tried building the arm of the T, drawing a rectangle on the side of it, then push/pulling the rectangle into a long board to form the leg of the T. If I later select the leg an try to move it, it sticks to the arm and both are stretched into a strange shape.
Next I tried building the leg separate from the arm and then moving it until it to the arm to make a T. If I leave a small space between the two shapes, I can later move the leg, but then my cumulative measurements will be wrong. Also, often it is impossible to position the leg at my chosen spot; it is as if the inference is off, and I am only allowed to position the leg either 1/8 inch to far to the left or to the right. This way also takes much more time.
Is there a way to build like my first method but prevent the shapes from sticking to each other?
