Only clockwise?

[Kenneth]

Hi,

Is it possible to define, in what direction a rotating part is allowed to move? E.g. only allowed to rotate clockwise.

HI @Kenneth

You only can define a motor where You will be able to define the direction too.

But this will not prevent a manual move into the other direction.

not directly...  but might try to use a variable rule limit...   this would allow you to set the range of the rotation...

Hmm... I dont think that will work in my case.

Will it preven a part from running/moving in the opposite direction?

What if you had an angle constraint with a variable rule limit set at a minimum of 0 and a max of 720 which would allow 2 revolutions. With that simple limit it could turn counterclockwise if it currently was at 90 and you change it to 45. (It couldn't go CCW from 0 because that would take a negative value which isn't allowed by the variable rule). What if you made an if/then rule that says if the the new value (45) is less than the current value (90) then subtract the difference (45) from 360 and use that value (315) for the move. Then I think it will go only clockwise.

Thats actually not a bad idea - going to give that a try and post an update how it goes

Thanks
