CREATE MASS THAT FOLLOWS TOPOGRAPHY

How to rationalize Topography as a Massing form using Divided Surface and panelization tools.

Method:

1. Make a Site family with a vertical model line and height parameter.

2. New Project - Make a Toposurface (or existing project with Topo)

3. New in-place Mass

4. 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

5. Copy a certain number of times in X direction. Basically, you are forming one part of a grid sampler...

6. Make a new Adaptive with the same number of points as step above. I made a 20 point adaptive.

7. Select all the points, make sure they are Adaptive, Spline through Points

8. You now have a 20pt Model Line spline... Load into Project

9. 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)

10. 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)

11. As the elements are copied, the Site families will host themselves to the Topography, and the Spline will adjust accordingly

12. Now, select all of the spline families and Create Form!

13. You can adjust how close to the original site the Massing form is by using the height parameter of the Site model line family
