Constraining a label to a path

[Sahay_R]

I have a parameter driven True North family, which works flawlessly. The label that is nested in this family also works flawlessly, reading off the values from the arrow as it rotates. My only problem - even when locked to the arrow, the label runs wild all over the place when the arrow rotates. I have tried to align it parallel to the arrow, tried to keep it perpendicular to the end of the arrow. This screenshot shows what I want. I have also attached the family.

AARRRGGGGHHHH.

So,

Your true north Generic Annotation has to rotate along the arrow?

If so: see attached file.

Cheers.

OMG. You just gave the label the same rotation parameter. Awesome.

@Sahay_R

It s not constrained properly that's why....but that's easy to fix, but one question before I load the screencast...what is the purpose of the Diameter parameter and the Perpendicular parameter? I tried flexing those but they seem not to be related to the North Arrow...just an invisible circle which doesn't seem to be relevant to anything

edit...solution already found above

The Perpendicular parameter was a trial that missed. The Radius parameter - that was how I forced the arrow to rotate the way I wanted it without falling to pieces all over the place. Thank you!

🙂 @Sahay_R 

cool .. Well they are not restraining anything and bot not really required... Just checked the solution too. I thought your intention was to runt the annotation along the circular path and not aligned to radius. But if that works for you all is good

[Sahay_R]

Actually I did - placed the tag where I wanted it and then applied the rotation parameter. It is glorious!

Cool 🙂 then u could also just lock it to the end point of the reference line rather than the line itself (and when instance is placed - the ref line should be set as workplane) no parameters required). Same way you would rotate nested elements in any other family
