Yet another post about Revit weirdness… Struggling with setting scope boxes to multiple views via Dynamo, I noticed that some of the views returned the “null” values. I opened the view that had a “null” value, and saw that the “Scope Box” parameter was grayed out:
The reason for this weird behaviour is simple: it turned out that Scope Box parameter becomes read-only if you modify the Crop Cregion sketch. Since the Revit Scope Box is a cube, it can’t be applied to those views that have non-rectangular Crop Region!

Counting something in Revit seems pretty easy, right? You’re able to extract lots of parameters from different element categories out of the box, and use them to create schedules or count quantities. This concept works great until you get to the system families. They usually make you scratch your head and turn your eyes towards Dynamo to get things done…
Say, we want to schedule the number of balusters by railing types. How are we supposed to count things like this?
The first thing that comes in mind – is to create a Railing schedule and check out available fields. And that’s when the first obstacle comes in your way: there’s no such thing as “Baluster” in the railing schedule:
The next step is to check railing instance or type parameters. Still, nothing useful here but baluster placement, that obviously can’t help us count the number of elements. Well, what if we check out available parameters in Dynamo?

An updated version of my Dynamo nodes package (rev.2017.6.2) is now live at Dynamopackages.com. This version contains the Dynamo node that builds a Navisworks search set XML from the input data:
Based on the original code by Luke Johnson from What Revit Wants (Bakery package), this node gives you the freedom in Navisworks XML file creation. You’re able to specify the Navisworks Search Set name & group, and choose which Navisworks parameter you’re going to use. This XML file stores data in the structured way that could be easily read by Navisworks. This means that you can use the power of Dynamo to automate your Navis searches, and even set the rules that couldn’t be otherwise done without workarounds. … Zhukoven.com dynamo package update brings Navisworks SearchSet XML creator
