Cam stop help

I’ll try to be succinct. 

I’m trying to model a resetting steel plate target for small-bore rifle shooting. 
The bit i’m currently stuck on is the stop peg which goes behind the small steel target (when it falls backwards), and which then acts as a cam to ‘flip’ the plate back to vertical when the plate is drawn (by pneumatics) downwards. 

In a nutshell, for the movement mechanism, I have managed to model up a simple shuttle slide (box section steel), with a shuttle and pneumatic ram inside, which is attached to the target plate with a lug (and revolving joint). I can animate the shuttle up and down, and even ‘fold’ back the plate. I just want to model a simple piece of material which will act as a ‘peg’ or ‘cam’’, and which will interrupt the plate as it is drawn downward, thus, re-setting it to vertical, and which then means it can be pushed back up by the shuttle when required. 

I can see how to constrain a joint to a set angle, but I cant see how to make an object interact with another, as if its contacting a real solid body. In other words, I want to be able to ‘knock over’ the plate, drag the shuttle down, and see the target upright itself again.

Any help would be appreciated.

If I follow you correctly, what you're after are 'Contact Sets'. 

 

Check out Assemble > Enable Contact Sets. You can maximize performance by defining small contact sets - if you ask Fusion to constantly evaluate the status of every object touching every other object. it's a lot of math, which can quickly bog down your system. If you have joints defined, then you probably just need to analyze contact between a couple of components to get one to push the other one.
