Dynamo Basics: Runs, Previews, and Lacing

Now that most of my posts are focused around Dynamo, I have noticed that many people leaving comments here are trying to troubleshoot a problem that they are having in Dynamo. Even though this might not be the best forum for troubleshooting issues (I would recommend the Dynamo Forum, instead), I have also noticed some simple and recurring issues that multiple people seem to be having. So this post an effort to address some common Dynamo issues and point out some features that you might not know about.

Make Hardscape Follow Topo Update

A little less than a year ago, I posted about how you can Make Hardscape Follow Topo with a very simple Dynamo definition. The main downside to this workflow is that it requires a corresponding Subregion with the same footprint as the Floor. Because it uses a Subregion to generate points, you also cannot control the amount of points that go into the Floor. But with a slightly more complicated definition, you can create the same result without a Subregion and even control how many points will modify the Floor.

Create a Water Solid with Spring Nodes

Revit does not have any built-in tools for modeling water, though I have previously shown how you can Model Water with Topo. But this method is more of a workaround and it does not work particularly well in section.

Now with Dynamo geometry tools and a couple of nodes from Spring Nodes, you can create a solid water element that perfectly follows your Topography.

Import Shapefiles with DynamoGIS

A few months ago, I posted about how you could use the Elk package to bring GIS data from Open Street Map into Dynamo. Open Street Map is a great resource if you do not have access to other GIS data. But if you do have other GIS data, such as shapefiles, then Elk is not very useful.

However, there is another package that can import shapefiles into Dynamo: DynamoGIS. For some reason, this package does not appear on the package manager website, but you can find it if you search the package manager from inside Dynamo.
