The joints are driving me nuts.

The joints are driving me nuts.

After a long talk with Dave, I thought (operative word: thought) I had it sussed.

 

Today I am trying to restructure some things.

 

Slowly slowly.  I get it.

 

But this is just getting beyond a joke.

 

Looking at the screen shot this is where I am stuck.

Yes, I am probably still doing it wrong.   Not having DIRECT contact is killing me.

(No offense to Dave)

It is more this covid crap.....

 

Anyway:  I have 2 pedals.  Badly built - yes.   But for show.

I have one sliding back/forward ok.  And a 10 degree title on the pedal.   Just to show off.

 

But then when I get to the second one...   It all falls over.

If I don't connect the pedal, it seems to fail, so I can't get that.

The post and pedal don't line up - or maybe they do as I have fixed it.   BRAIN FAILURE!

 

The RIGHT (looking from where you would be if you are using them) is giving the grief.

 

I create the joint and it slides.  (I learnt that I had to stop the rotation to make things nicer)

All +/- 80mm.

 

But as soon as I either put the pedal on, or *link* the two pedals....  I am luck to move it 20mm.

 

I've been at it for HOURS - literally.  (Honestly even)

 

Dave was explaining the hierarchy of joints.  I thought I got it.

But Fusion has other ideas.

 

I've tried all ways of ordering things.  I step back one step and it works.

Apply that last step and...  all falls over.

 

Please (someone) have a look at/in the time line where shown and explain why the joints are messing up.

 

(On a tangent:  Usually when I export files they are .f3d or .3mf  Today they are .f3z and neither of the others are visible.  What's going on?)

The problem is contact sets.  General advice is to stay away from contacts.  They can work in limited cases, but in general, they will at best cause performance problems, and at worst, cause interactions like this.

Thanks very much.

 

I didn't know that was.... persistent.    I was doing something else and needed that set.

 

Live and learn.

 

Now on to the next joint.   😉
