Joint issue, revolve

[robpage]

 I'm a noob, having trouble making the "revolute" function work.  If you have a sec, I put a vid up here which demonstrates the problem far quicker than I could type it out.  Thanks

@robpage,

Some suggestions:

1) You have not grounded any of your components.  It is a good idea to ground one so that Fusion knows which one to rotate when you drag the joint.

2) Fusion is a bit picky when selecting and dragging joints like this.  If you are having some problems, try orbiting to look more directly at the joint.

3) I am not a fan of the as-built joints.  I have noticed some...interesting behavior with them (for example, the joint marker moving, as you noticed).  I recommend using the standard joint rather than the as-built.  This, however, is a personal preference.

4) Fix the errors in the timeline.  Fusion really does not like to have these and they may be causing some of your issues.

Left mouse drag the component you want the joint to visualise, never tried to move a joint handle, thats a new one,

You can also right click the joint, in the browser, and click animate model, for that joint, set limits etc

I have not seen any joints jump from their origin,

Agree timeline errors are not good.

Thanks guys.  I was finally able to get it to work using regular joints (not as-built) and by grounding both posts for the gears.  Turns out if you double click the rotation handle then you can rotate - though pretty sluggishly.  Don't know why the rotation in as-built was acting so weird.  I got this from this tutorial and did it exactly as he did multiple times.  Strange.  Even though I've found a workaround, I'd still like to figure out what the problem is.

Sorry, as a noobie, I don't know what "errors in the timeline" are.  Lame, I know.

@robpage,

No problem.

When you see things highlighted red or yellow in the timeline, it means there is a problem.

Yellow highlighting is a warning.  Often it means Fusion is using cached data to solve something.  For example, if you projected a line from a component to make a sketch and then deleted the component later Fusion would highlight the sketch in yellow.  In this case it is sometimes better to remove a component rather than delete it, as this will preserve the geometry for use with other entities (like sketches).

Red highlighting is an error.  This can be caused by things that cannot be computed (like a pipe that has too narrow of a radius) or a deleted feature.

If you right-click on the error/warning in the timeline you should be able to review the message.  Sometimes they are easy to fix, sometimes they are not.  Either way, however, warnings or errors can cause downstream issues.

Wow, so helpful.  Thanks!
