How to revolve a sliding joint around an axis

I have an SD card that slides in a holder (see attached image)

I want to rotate both of these around two pins/lugs at the edge of the holder.

I couldn't get this to work and then while editing this thought that I found the solution. (thought it was worth sharing)

 

Question: Is the correct course for getting an assembly of jointed components to move relative to another set of jointed components just to create the joints in the correct order?

 

Not working:

Slide: create sd card that slides in a slot in the holder

then

Revolve: then revolve card holder around its pins

Outcome: Rotating card holder leaves the SD card stationary

 

Working:

Revolve: rotate card holder around its pins

then

Slide:  slide the sd card in the card holder

Outcome: Rotating the holder around its axis and the SD card revolves too and can rotate and slide at same time as I expected.

One unexpected outcome is when I set the revolve limits to say 10deg and 20deg, the sd card does not match it and stays at 0 deg but when I drag the card and revolve, they all revolve together but the sd card is 10deg out of its correct slot position to match the 10deg of the holder. (I believe this unexpected outcome is related to the below also)

 

If I move the history marker to between the revolve and slide joints (i.e. only revolve joint is present) and I rotate the joint, the SD card stays put. How do I get the SD card to move along with the revolve of its holder? If I were to put a rigid joint, I couldn't then make it slide later?

All working as expected here.  

 

Adding joint limits does break the file, because you are using As Built Joints and not regular Joints.

 

Might help...
