I am making a pattern for a stair case to use for fabricating railings. I want to make the overall rise and run the driving dimensions in a linear sketch pattern, but I cannot figure out how to make the angle of the linear pattern non-driving. I know this is possible, I've seen videos of people using a linear sketch pattern for this, but never shows how to work around that.
For a linear sketch pattern, after you create it, the angle isn't modifiable, in fact it just places the geometry at the angle you want and leaves it undefined (the angle dimension doesn't even exist!). (At least not in SW 2015). You have to create your own angle dimension afterwards, then use that to control it.
See the attached video:

Oops. I should learn how to read.
Great answer Dan.
Dan,
Thank you for the response! video was helpful.. I tried to reproduce the pattern in the vid, but when I add that angle dimension from the dimx spacing construction line to a construction line on the x axis, my sketch becomes over defined. I haven't added any relations or other dimensions.. not sure what else it could be. I am on 2017.

Before you added the angle dimension, was it fully defined?
Can you share a screenshot of the sketch right before you add the angle dimension? (make sure that you have relations view turned on, so I can see the constraints).
Walker,
Add your dimension. Then click on the dimension and go to the 3rd tab (Other) in the dimension options box. Just check Driven.
