How to make an angled constraint "joint". Frustrated Inventor user

Hi all,

I'm trying to connect the top of a piston to the bed of a dump truck.  This is a play project for my 3 year old son.  

Here's the link.

I'm struggling with using Fusion 360's joint commands.  In inventor, I'd be able to control the angle of faces with respect to each other even if they weren't coplanar.  In my project, the top of the highest piston has a face that somehow got slightly off axis and I can't seem to align it to make it parallel with the chassis and bed walls.  If I could constrain that, then I could pick a spot on the top of the dump bed to connect the top piece to the bed and let it articulate.  As it is, every time I try to make a rigid joint to the bed, the slight off axis alignment makes the whole thing fail to solve.  I appreciate your help with this project.

Hi Roger,

 

I made a "quick-and-dirty" fix:

1) changed the two piston joints from "slider" to "cylindrical"

2) added a "slider" between "Component15" and "Bed"

3) just for fun: added a "motion-study" that you can play. Alternatively you can drive your "Rev4" - or just try "click and drag" on the Bed-component.

Remarks:

1) the structure (sketch/body/component/assembly) of your file is somewhat less than perfect. This creates an unnecessary burden to the user (to you).  Do yourself a favour and stick to rule#1 and rule #2

2) don´t ignore warnings (two sketches) - it might hurt you later in the design process

3) get comfortable with joints. Learn, experiment, test. They are extremely important if you want to effectively work with assemblies in Fusion 360. If you are coming from inventor (like me), at the beginning it might be frustrating (for me: very frustrating). But keep going, it´s worth the effort!
