Unable to indicate a 180 deg angular dimension on drawing

[emillner]

I have identical features on a round part and I want to indicate a centerline running through the features and specifying 180 deg +/1 deg...since I do not have two edges to select, how can I specify this angular dimension in the drawing?  Is it possible?  Thanks for your help.

This is not a normal angular dimension for Fusion 360 drawing environment but you can achieve it if you have two separate lines forming 180 degrees.  When you place the Angular Dimension, do not use Automatic, you will press the space bar to use designated points. You can also use two bisector center lines instead of a model sketch if you would like.  I did not show this method in the Screencast.  Follow the Screencast and you will see how to do it.  If you want to add a second set of sketch lines, you can create a center mark or you can add a regular center mark in the drawing, that is just cosmetic.

Great!  Thanks for your help.

Hi @jhackney1972 ,

Nicely done! Just curious, with the model sketch approach, does the line type (reference vs center line) applied to the sketch geometry when visible in the drawing create any issues?

Cheers, Andrew

Fusion will only allow lines, either sketch or reference, to come across to the drawing.  All sketch lines will come in as, what I call, phantom lines in the drawing environment you have no choice.  I wish the application allowed me to change the lines to center.  In this case I had to use a two full lines but often I just use a short segment to get enough to place the dimension then I cover it up with a center mark, bisector center line or some other in the drawing.  I wrote a blog article on the use of model sketches in Fusion 360 awhile back, here is a link if you are interested.
