Making angles same

rune_thorsen

Hi, as a newbie I can't figure out how to constrain two (or more) angles to be equale.
E.G. I have an angle set to 12 degrees. I want to constrain other angles to be identical so if I change the 'master' angle  to 10 degrees they will follow and become 10 degrees. (Not having to change manually all values)

You can use variables to define the angle and then use that variable whenever you dimension an angle.  This is a link for webinar on variables:  https://www.onshape.com/videos/webinar-variables-in-onshape-july-19-2016.

You can set lines as equal because they are entities you can pick.  Angle is not an entity by itself, it is only a measurement between 2 entities.  Therefore, to set angles as equal, we need dimensions.  Variables & equations are very handy when you have to deal with dimensions.

Thanks. I hoped for a equal constraint between angles (or pair of lines).
What I expected to set angle dimensions as driven and be able to apply an equal constraint among them.

You could, using perpendicular lines.  However, in my opinion having too many constraints will make future editing very hard.  It is best to avoid if possible.

Thanks
Conclusion, you have to workaround not being able to set angles to equal as you would set line lengths to equal.
