When you want to place your shapes were you want, not where TCM thinks that you want, you could set Point Snapping off and then you can move all the nodes, line handles and text labels exactly to the pixel where you want. If you set the autoresize toggle off, you can resize the diagram shapes and table rows and columns by hand. If you have difficulty to access a particular shape because it is too close to another shape, you can try to temporarily zoom in. But, when you use TCM a lot, you will inevitably find a situation in which an editor messes up your drawing. If that is so, please let us know.
