Locked Angles and Distances UNLOCK themselves !

HI Community

I have observed a major fault when working with joints in an assembly context.
On a cylindrical joint I have locked its angle and distance but later when design was saved, the locking state was GONE !!!

How can I make sure they are 100% persistent and stay in place as long as their references exist ?

This behavior is very scary since you can now never trust the software to behave as expected, any experience on this and how to fix it?

Thank you

It is possible you locked a joint occurrence and later edited a feature or did something that recomputed the timeline in a way that caused uncaptured moves/locks to be lost.

 

Locking/suppressing/driving joints, dragging/moving components are all actions that can be done in batch and then optionally captured into one Position feature in the timeline.

 

Until they are captured, they are vulnerable to being lost by some timeline edits. Most edits should keep these uncaptured states but some will cause them to be reset to the computed timeline state.

 

for example, I think rolling back the timeline marker and the rolling forward will do this reset.

 

I’m not sure this is what you are seeing but it is possible. If you want to retain this lock state and do things like rolling, you can capture it as a position feature. The capture/revert commands will be visible at end of toolbar when you have uncaptured moves/locks.

thanks I will try, so you say capture position solves the problem?

capture position "solves" the problem, but introduces the possibilities for other problems. capture position is frequently the cause of other errors down the road and is usually best avoided. does the joint have to be absolutely locked, or can you set a rest position instead. setting the rest would be persistent and wouldn't require position capture or redoing.

Thanks for the tip, with an example I may explain it better:

 

When assembling Stuff, we often have to use "align" for instance to mount a square profile onto another (lets say the form a t shape after assembly).

Since Align "parallel" cannot be made directly into a joint (unless you have a good tip there) , I have to use "cylindrical" and then lock the angle.

I will try to use rest position, I hope it can be achieved with one click as well..

An actual example would be way better than a verbal description.  (i.e. -a model demonstrating the situation)

 


...When assembling Stuff, we often have to use "align" ...

If your using move or align a lot to position components relative to each other, it is probably time to revisit how joints are suppose to work in fusion.   Those commands are rarely needed in fusion, and lead to all sorts of modeling frustrations.

 

there are 2 ways to position components relative to each other-

1-built compnents "in place" (doesn't include moves or allign) and use an as built joint

2-use a regular joint

in all cases, delete any resulting position captures from your timeline

 

other methods just lead to broken models and heartache.
