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.
There are a wide variety of 3D Models that can be added as data sources in InfraWorks. The options for 3D Models Files are .3ds, .dae, .dxf, .fbx, and .obj. With the right version you can also add IMX, Revit, IFC, and LandXML files as well. But for this post, I am going to be working with .fbx files exported from Revit.
FBX is a 3D exchange format that can be used and generated by a variety of programs and tools. In Revit, FBX is towards the top of the Export menu.
Like with any 3D export, you want to make sure you are in a 3D view. Unlike with DWG or IFC export, there are not many settings to be adjusted.
One of the first issues a new user, particularly a landscape architect, might encounter in Revit is the general lack of control. How do you control the graphics? How do you get the results that you want? It can be a bit overwhelming. Understanding Categories and Subcategories is the first part of controlling the model (and thus graphics) and they are also critical for exporting and sharing your data properly.
Categories are the different types of Families within Revit. Each Family Category has different properties and parameters. The Main Categories are hardwired into Revit; they cannot be renamed, created, or deleted. But within the Categories there are Subcategories. Some of these are hardwired (again, cannot be deleted) but you can create as many Subcategories (Subcats) as you want and delete the unnecessary ones.
In the 2015 Architectural Template, the Site Category has 8 Subcategories, but only Hidden Lines, Pads, Project Base Point, and Survey Point are necessary. Continue reading
If you are working closely with any discipline that is still using AutoCAD, you will need to export your Revit file to dwg relatively frequently. If you want your dwg export to look like a typical AutoCAD file, the DWG Export Setups will require a bit of tweaking. There are also a few basic settings that when done correctly, will save you time.
For reference, here is what a site plan looks like when exported with the default settings (from the Architectural template).
