Bespoke development

Your workflow, built into SketchUp.

The ready-made extensions started as tools for real projects. If your office repeats the same twenty clicks every day, that is a tool waiting to be written.

ModuSmith writes custom Ruby extensions for SketchUp: batch tools, importers for your survey or CAD data, report generators, and company-standard drawing setups.

Brief free
You describe the job and send a sample model. I reply with questions and a first recommendation before anything is promised.
Specification
A written spec lists every tool, dialog and output, with a fixed quote per milestone. Nothing is coded until you agree it.
Milestone builds
You install each stage as a dev .rbz and test it in your own SketchUp. Bug reports and screenshots feed straight into the next build.
Delivery and support
The final signed .rbz, a short user guide, and three months of fixes. Source-code ownership is available on request.

Toolbars, inferencing and undo behave the way you already expect.

Your data stays put

No cloud accounts. Models never leave your machine.

DIRECT

Talk to the developer

Feature requests go to the person who writes the code.

Questions

Before you buy

How do I install an extension?

In SketchUp open Extensions → Extension Manager → Install Extension, choose the .rbz file you downloaded and restart SketchUp. The toolbar appears under View → Toolbars.

Which SketchUp versions are supported?

SketchUp 2025 on Windows for all extensions, and SketchUp 2026 for GeoRef. macOS support is planned once the Windows builds are stable.

What does a beta or early-access licence mean?

You get the extension now at a lower price, plus every update up to and including version 1.0 at no extra cost.

Can I move my licence to a new computer?

Yes. Each licence covers two seats, and you can release a seat from your account at any time.

What does custom development cost?

Small utilities usually cost less than a week of a draughtsperson's time. Larger tools are quoted per milestone after the written specification, so you know the full price up front.
