Studio and linkages

[Anonymous]

Open the iam, drive link1; angle 1. Leave it at 0 deg.
Go to Studio, hmmmmm seems to be different.
Run animation 1!!!!!!!!!
Edit the first segment of angle1, don't change anything just cancel out and
run the animation again. Reset to the beginning and we're back to where we
started.
This is a simplified version of an actual (confidential) linkage that I've
designed that had similar flipping over center problems.

RK: The angle constraint is set to 0deg in the model state (i.e.
assembly environment). In the Studio environment however, the first
segment of the animation runs from 45deg -> 0deg, so I'd expect to see
the 45deg position when entering Studio.

RK: I see no difference in the animation after cancelling out of the
Animate Constraint dialog.

RK: Would you be able to capture the problem your seeign using Camtasia
or another video capture utility?

Randy,
See attached. Are you not seeing link2 flip over center in Studio?

Yes, I do see what you're talking about now. You can reproduce the
flipping just by dragging the timeslider back and forth. I'll submit
this to development and dig around a bit more to see if there's a simple
workaround for it in the meantime.

Thank you,

Actually, it looks to be an issue for the constraint solver itself and
not specific to Studio. If you suppress the angle constrant and drag
the assembly around, you can get the flip to occur as well.

More to come...
