MetricMonkey
MetricMonkey is a Windows desktop feasibility and massing toolkit built on Rhino 7 and Grasshopper that automates building extrusions, mixed-use stacking, GIS-backed context, and optional streaming into Revit through Rhino.Inside.
MetricMonkey comes from Parametric Monkey Pty Ltd and targets architects and designers who already work in McNeel Rhinoceros and want faster iteration on envelopes, ratios, and area metrics without leaving that environment (MetricMonkey marketing pages, 2026). The product pairs a guided interface with Grasshopper components so advanced users can publish custom inputs and wire studio scripts into the same UI.
Workflow descriptions cover drawing or importing footprints, setting height or storey limits, merging massing pieces, and using a function system for mixed-use towers with colour and floor-to-floor defaults handled for you. GIS-oriented features include importing geo-referenced overlays such as cadastre, roads, and planning zones, plus filters to hunt for development sites by suburb and regulatory limits like floor space ratio caps.
Revit-oriented teams get a documented path through Rhino.Inside Revit: the vendor states MetricMonkey can push native Revit elements such as topography, mass families, levels, floors, and materials, while aligning survey and project base points for geo-consistent handoff.
Commercial packaging lists Basic, Business, and Professional tiers with different mixes of analysis, GIS, licensing style, and support, but purchase buttons were marked coming soon at the time of review; confirm current availability directly with Parametric Monkey.

Pros and cons
Pros
- Stays inside Rhino, a common tool for complex geometry and scripting-heavy practices.
- Combines click-driven study with Grasshopper escape hatches for bespoke logic.
- Explicit Revit pathway for offices that need native elements downstream.
- Clear tier ladder for solo versus floating licence needs.
Cons
- Windows and Rhino 7 dependency means no macOS-native story on the marketing site.
- General availability was still gated behind coming-soon flows when reviewed; verify purchase options.
- GIS datasets may be add-ons or region-specific; read the dataset index before promising coverage.
Key features
Rhino and Grasshopper core: Ships as a Rhino 7 Windows application with bundled Grasshopper components for extending the standard UI.
Automated massing: Extrudes footprints to storey or height targets, joins mass fragments, and generates floorplates from simple inputs.
GIS context: Imports referenced datasets for planning overlays and urban context; optional library depends on city coverage listed in the dataset index.
Mixed-use functions: Models stacked programmes with switching between building functions and coordinated presentation defaults.
Revit handoff: Documents streaming into Revit via Rhino.Inside for masses, levels, floors, topography, and coordinated survey points.

Frequently asked questions
What host software does MetricMonkey need?
Public materials describe it as built on Rhinoceros 7 for Windows with Grasshopper 1.0. You run it locally on your PC inside that stack.
Can MetricMonkey talk to Revit?
Yes. Documentation references streaming geometry and data into Autodesk Revit through Rhino.Inside Revit, including masses, levels, floors, topography, and survey alignment.
Is MetricMonkey only extrusions?
No. Marketing copy positions extrusions as one path while also advertising custom massing tools, mixed-use functions, and hooks for your own Rhino or Grasshopper geometry.
Does MetricMonkey include GIS data out of the box?
It can integrate geo-referenced datasets and links to a dataset index, with a note that some supplies may be separate or regional. Professional tier messaging includes full GIS integration.
Who makes MetricMonkey?
Parametric Monkey Pty Ltd owns the MetricMonkey trademark according to the site footer.
