Assembly 4 - Double Movement

[gsandy]

I have a four sided cardboard box that lays flat.
Through Assembly 4 - Animate Assembly I can get this box to open up 90 degrees.
I have attached a small tab to the short edge, and it moves as the box is opened.
After the box is fully opened I wish to swing this tab 90 degrees, as shown on screen shot.
I have tried adding an Assembly 4 - Variable to the Small Tab Sketch angle but this does not work!
Is there another way to get the small tab rotating 90 degrees?

Assembly4 can have only one independent variable.

One common solution is to have an independent time variable and then define other variables in terms of time.

Or, it is also possible to use a conditional statement https://wiki.freecadweb.org/Expressions.
See example here:https://forum.freecadweb.org/viewtopic. ... 50#p615650

Thanks guys.
Got it working by playing around with the Map Mode of the small tab sketch, see attachment. I have one variable controlling two movements.

Applied the same principle to get movement on the three directions of a CNC machine I modeled up.
