(Part of the What’s New in the Revit 2010 API series)
For some people, the measure of a CAD API is always how many different types of elements it can create. Revit got off to a slow start in this category, but it continues to get stronger.
In this release, the new Revit API capabilities seem divided into:
- A significant amount of new MEP element creation
- A little bit of new Structure / Rebar options
- A significant amount of new capabilities around family content creation.
- A few very interesting things around the new freeform geometry and divided surface modeling in Revit 2010.
All in all, Revit can now create 70-100 different types of elements (depending on how you count the family content-related things).
What’s New for MEP Creation?
Here are the new MEP-oriented creation capabilities:
- Cross Fitting
(not being very MEP-savvy myself, I can’t add any real commentary to them other than to say it looks like an impressive list).
What’s New in Family Content Creation?
This whole area is new and exciting…
- Solid Forms
- Form By Cap
- Form By ThickenSingleSurface
- Supporting Elements
- Angular Dimension
- ArcLength Dimension
- Linear Dimension
- Radial Dimension
- Symbolic Curve
- Alignment (this looks interesting)
- Vertex Index Pair (this is a construct which defines how different profiles in a blend link together, I believe)
- Family Symbol Profile
- More Elements
- Model Text
- Freeform Modeling / Surfacing
- Curve By Points
- Divided Surface
- Reference Point
A Brief Story on Reference Points
A year or so ago I pinged Emile Kfouri, the Revit Platform Product Manager about why there were no “Points” in Revit (I can’t recall why I needed them – but I do know how old-time CAD people’s heads look like they’re going to explode when I say that they don’t exist). He said “Points are not BIM” – and I came to agree with the statement, in general (not that Lines are BIM – and they were prevalent in Revit still). In any case – while they’re not BIM, they are quite handy for building things – and it’s nice to see them in there.
A Few More…
Finally, there are a couple last additions and changes…
- Rebars defined by RebarShapes
- Hermite Splines (these are one of the building blocks of the new freeform modeling capabilities)
- Plane from Curves
- Topography Surface (Now this looks very interesting – just pass in an array of XYZ points and get back a surface? I haven’t had a chance to try it out yet – but it should be cool!)

All in all, this release presents a great deal of new capabilities around Element creation… certainly enough to keep most of us busy for the next year until Revit 2011 comes out!
