Since railings are a system family, you can’t assign geometry to subcategories to control their object styles, the way you can with normal families. So if you have a railing with cables that are reading too heavily, it can be tricky to adjust only the cables.
One thing you can do is reduce the size of the cable profile – if they’re modeled at 1/4″ in diameter, try changing that to 1/16″.
Another thing you can do is go into Object Styles and change the line weight of Rails (found under Railings). If the smallest line weight isn’t fine enough, you can change the color from black to grey. Of course, this will change the appearance of all rails in your model, which might not be what you want.
If you only want to change the appearance in certain views, try a Visibility/Graphic Override. This is great if the railing you want to change is the only railing in the view.
If you know a better method, please leave a comment!
All surface patterns (and cut patterns) in Revit are displayed with a model line weight of 1. If you want to make them thinner, you’ll have to go into the Line Weight and change the settings for that first line weight.
Of course that will also change anything else that’s set to that line weight. If you are setting up custom line weights, it’s a good idea to reserve 1 for surface patterns and 2 for ceiling patterns, making 3 your smallest general-use lineweight.
Another way to lighten only a particular surface pattern is to change its color from black to grey. The color setting is specific to the material, so this method won’t change other objects unexpectedly.
Open Object Styles (I have a keyboard shortcut set to OS) and scroll down to the Topography category. Click the plus button to see the different subcategories. I changed the projection line weight of my Primary Contours from 6 to 3 so they wouldn’t dominate my site plan so much.
