I recently posted about converting Topography to massing forms using a somewhat “manual”, yet lofted and smooth, method:
Convert Revit Topography into Massing Forms
Harry provides some code to do a similar thing with triangulated flat faces over here:

Have you ever wanted to rationalise your Topography as a Massing form, perhaps so you could use Divided Surface and panelization tools on the topo?
Here is one method:
- Make a Site family with a vertical model line and height parameter (see sample file at end of post)
- New Project – Make a Toposurface (or existing project with Topo)
- New in-place Mass
- Place the Site family on the Topo in one corner – it will detect the Topo and host itself to it, even though you are in the Massing environment
- Copy a certain number of times in X direction. Basically, you are forming one part of a grid sampler…
- Make a new Adaptive with the same number of points as step above. I made a 20 point adaptive.
- Select all the points, make sure they are Adaptive, Spline through Points
- You now have a 20pt Model Line spline… Load into Project
- In Massing environment, place the 20pt component by clicking on the very top of the vertical Model Lines from the Site family (as you place it, the points will change to a smaller point size to show it is “living” on the top of that line)
- Now, select the whole row of Site families and the 20pt component and copy it along the other planar axis (this is the other part of the sample grid mentioned in step 5)
- As the elements are copied, the Site families will host themselves to the Topography, and the Spline will adjust accordingly
- Now, select all of the spline families and Create Form!
- You can adjust how close to the original site the Massing form is by using the height parameter of the Site model line family
The image shows the sample surface above, and the original Toposurface below.
The only limitation I found was that if the form is “flat” at some point, the Create Form may not work. However, if each Spline does vary up and down, it should work ok.

Recent post by Jay Holland demonstrates the methodology they adopted to create the Revit model for a multilevel residential project. As it had lots of repeatable elements, its interesting to hear how Massing and Groups were used to limit the impact of changes and reduce rework.

- Make a rectangular extrusion form
- Make a revolve form using funny looking profile shown above – switch to void
- Cut geometry, and then adjust grips as necessary to make it look nice

In response to:
You will find below a visual diary of some site master planning options – the Divide and Repeat tool was used to layout out the units.
Here is a very concise how-to:
- Make a new Mass or Adaptive family (in-place or component)
- Draw a Spline
- Select it and hit Divide Path
- Place a two-point based Generic Model Adaptive family spanning two of the points
- Select it, and then click the Repeat button
