Generative Geometry
Places hundreds of ready-made parametric shapes — boxes, domes, vaults,
twisted towers, polyhedra and more — into your model as real Revit masses
you can resize, move, slice and build walls or curtain systems on at any
time.
How to use
Open Generative Geometry from Revit with your project open. The window
reads your project's length units and lists any shapes it placed
before under In project.
Pick a shape from the Library. Shapes are grouped into families —
open a family to browse it, or type in the search box to find a shape
by name. There are more than 800 to choose from.
Set its dimensions on the right. Every value is in your project's
units, and the 3D preview in the middle updates as you type. Drag to
orbit the preview, scroll to zoom, and hold Shift (or use the right
mouse button) to pan.
Choose how to place it under Place as:
Massing family — a native Revit mass. Mass floors, divided
surfaces, walls by face and curtain systems all work on it, from this
window or from Revit's own Massing & Site tools.
Simple solid — a lightweight solid for quick studies. It can't
host the by-face tools, but you can convert it to a mass later.
Optionally open Modifiers to rotate, twist, taper, distort or slice
the shape. Slices are flat cuts from any of the six sides, and the
shape always stays a closed solid.
Set the Position (0, 0 is the project's centre) and click
Place in Revit. Each new shape lands beside the previous one, and
names number themselves (Box 1, Box 2, …) unless you type your own.
To change a placed shape, open In project and select it. Adjust any
value, mode or modifier, then click Apply changes — the shape is
rebuilt in place, keeping its identity in the model. Show selects
and zooms to it in Revit; Delete removes it after a second click to
confirm; Done returns to placing new shapes.
For a placed mass, two extra sections appear while editing:
Mass floors — tick the levels that should get a mass floor. Levels
that cross the shape are marked.
Build on faces — click Divide faces…, Walls on faces… or
Curtain system on faces…, then click the faces you want in Revit
and press Finish. Esc cancels without changing anything.
Good to know
Shapes stay editable for good. Each one remembers its own recipe inside
the model, so you can close the plugin, reopen the project next week and
still reshape, move, slice or convert it.
Moving a shape in Revit is fine — the plugin shows its real position the
next time you edit it, so nothing snaps back.
The preview tells you what Revit will build. The chips over the preview
show the overall size, a rough floor count, and whether the shape will
be a true smooth solid, an exact flat-faced solid, or a finely faceted
one (twisted, tapered or distorted shapes that have no smooth form).
Round shapes — spheres, domes, vaults, knots, twisted towers — are
placed as true smooth solids wherever Revit can build them that way, not
as faceted approximations. Polyhedra are exact flat-faced solids.
Click Refresh at any time to re-read the project — for example after
deleting a shape in Revit or switching to another project.
Placed a mass but can't see it? Turn on Show Mass on Revit's
Massing & Site tab.
Walls on faces uses the project's default wall type, and Curtain
system on faces needs a curtain system type loaded in the project.
Faces that can't host a wall are skipped and counted for you.
The massing family mode relies on the Conceptual Mass family template
that ships with Revit. If it isn't installed on a machine, the plugin
says so — placing as a simple solid still works.
Every placement or change is a single Revit undo step.
