pin-slot joint animation

Hello,

 

Can anyone help me diagnose my problem? I want to animate my joint but Fusion says no. This design is for a telescoping leg. The outer tube (component: Slot) has a path for the pin of the inner tube (component: Pin) to slide through and rest in notches that allow the leg to hold position at different heights. I want to animate the “Pin” sliding through the “Slot”. To do this I am using the “Planar” joint type in combination with Tangent Relationship (also in the Assemble menu). In the attached picture, you can see the sketch I embossed to create the “slot”.

 

I know the Planar joint type will work with curved slots on flat surfaces. But my design is cylindrical and I’m a newbie. Is my request beyond the programs limits? Or do I need to find a way to create a true slot on a curved surface different from my emboss method?

 

Does using the “emboss” approach mean that it’s not a true slot. I can’t choose the full inner surface when selecting it and the pin to create a Tangent Relationship. I haven’t found anything on working with splines (then offsetting and closing the sketch and extruding to create a slot) either.

Hi,

 

I would strongly recommend that you do the embedded tutorials in the Fusion Documentation and also some of the

Self-Paced Learning to help you to learn fusion faster and better. They can be found here:

It is also much easier for the forum to help you if you attach your file AND a screenshot of what you want to achieve

and what the problem is. You can create a file to export like this:

Time spent on the tutorials and self paced learning will not be wasted. Also check out the three RULES that are pinned to the forum for further guidance.

 

The use of Emboss seems to have worked in the same way an an Extrude Cut. It is not the usual way you would do

this operation but I cannot see any reason why it might be causing a problem.

 

There are two joint types you could use, the Planar joint and the Pin Slot joint. Without the file the forum cannot

have a close look and play around to help find a solution.

 

One thing I can tell you is that you have a number of moves in the timeline that you almost certainly didn't need and

probably shouldn't have done. It should be a rare thing to move stuff around in a model. Newer users typically move

things because they cannot see, this is where the Eye icon in the Browser tree should be used; or because they are

under the misunderstanding that they are joining something to something else. In fusion, you should always use

joints to connect components and move them around. The Move command exists for a reason but has the

detrimental effect of slowing performance by making fusion re-calculate EVERY time you use one. Fine for one or

two but death for a complex model and many of them.

 

Cheers
