Random Rotation and Height

After seeing the FamilyInstance.SetRotation node in Dynamo, I wanted to figure out how to randomly rotate elements. There are typically not many elements that you would want to rotate randomly, but it can be done to plantings to make them appear more naturalistic in renderings.

And if you are assigning a random rotation to your plantings, then it would also be useful to randomize their height (within a specified range).

Free-Form Pebbles and Rocks

While hunting around for some Dynamo resources, I recently stumbled upon an old blog post from Zach Kron’s buildz, about creating a pebble shape in Revit. I have previously attempted to do this myself (to create the form for my simple, scaleable rock), but since I have very little experience in the Massing environment, I found the process rather difficult. But as Zach shows, it can be quite simple.

Complex Planting Graphics, Simplified

Almost exactly 6 months ago, I posted about how you could create a Planting family that had a complex, scaleable plan graphic. The entire process involved creating a rather complex framework and was limited to using splines. However, a while later I learned that neither of those are necessary.

So here is the slightly simpler (and much less time consuming) way to create a complex, scaleable planting graphic.

Complex Planting Graphics

After posting about Site Analysis with Detail Components, someone asked if the following graphic/ trees were made in Revit.

The short answer is probably not (though I honestly do not know, since I did not make this lovely graphic). But the question made me wonder, could you make a scaleable tree symbol like that in Revit in reasonable amount of time? Turns out, yes, you can.
