So I have a threaded rod (blue or orange ) doing a revolute motion (from grounded green component) and a block (red and puple) with a sliding motion (from the same grounded green component too) and I want to motion link them so when I rotate the rod the other component slide and if I slide the block it rotate the rod.So is there any math about this ? Like some spreadsheet or something ?
To give the best help, the Forum needs your model. If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

it should be a fairly simple Motion Link between the translation in the Slider for the blocks, and the rotation in the Revolute for the rods. The ratio will depend on the thread pitch. If you want super-accurate motion, then you will have to figure out the linear distance per revolution of the threaded rod, which I think is related to the thread pitch. If you share your model here, there are lots of people who will help.
I added a Motion Link to only one of the screws and slider block. It is the last one in the Joints list of the attached model. As I explained in the video, Fusion 360 has a problem with animating a Revolve Joint "continuously". You might get away with a Motion Study but they are usually too fast.
