First, what a great product for a fraction of the price of Erwin.
I do have a question though regarding the visual arrangements of the lines representing the relationships between tables. Is that a way to square off the lines like in Erwin, so far the lines are all angled and straight which really scatters the visual affect, I need to bend them and have them snap to square corners. Any help would be appreciated.
TDM3 only allows you to add break points to relationship lines:
select a relationship, press CTRL and click the line to add a break point. Drag and drop the break point to the required position.
