Direction angle in a rotational joint

franciscoascruz — Tue, 16 Feb 2021 13:13:21 GMT

Hi!

Does anybody know how I can change de direction of the angle when using Rotational Joint function from clockwise to anticlockwise?

I saw that sometimes angle direction is clockwise and in other cases anticlockwise, but I still don't understand what causes that and how I can change it from one to another...

I've attached some pictures of the situation.

Thank you! Have a good day!

Attach assembly here.

Thank you for replying! I've attached the assemble, hope it works...

However, in this assemble isn't very problematic if the angle direction is clockwise or anticlockwise. I just want to understand what defines the angle orientation in the first place and if it's possible to change it if the joint is already created?

Thank you again for the help!

I do not own a rar extractor.

I have only Windows OS to Zip/Extract files.

Oh, sorry... Once is a basic assemble, probably, it will work if I send just the assemble and the parts. Hope it works this time!

Thank you for your time, again!

Hi! The rotational arrow basically follows the right hand rule. When the rotation vector points up, the rotational arrow points counterclockwise, and vice versa. For Rotational Joint, this direction isn't important. It just show you where the reference vector is. It does not dictate if the component should rotate clockwise or counterclockwise.

Many thanks!
