How can I change link types in TA in Gantt and Grid modes?
Time Architect allows you to model both (the normal) Finish - Start relationship (where the start time of the second task is set based on the finish time of the first) and the less used (but often very useful) Start - Finish relationship (where the finish time of the second task is set based on the start time of the first task).
…This button is not the most obvious button on TA’s screens:
This button is only active if the current element has links to one or more parent elements.
