I came across this video that Aaron Maller posted a few days ago and I thought it was worth sharing. In it, Aaron is simply laying out some Parking families in Revit, but it is interesting to see the various ways in which people build and use their own content. There are almost always things that you can learn from other people to improve your own methods and content.
It is easy to forget how often fences are used on projects. If nothing else, they are often used to enclose dumpsters. Here is a wood fence, the first in a line of fences and gates.
Any family can be as simple or complex as you want it to be. I prefer creating more complex parameter-driven families that can be used to create many different types. So in this fence family the height, length(span), post, rail, picket size, and spacing are all entirely adjustable.
Since this is a wood fence, the length of the fence will actually adjust based on the picket size and spacing. You can see the actual length in Length_Actual.
