TopMod for PC: How to Download & Install on Windows

Introduction

If you want to build smooth, organic 3D meshes by pushing and pulling their topology, TopMod is the free tool that lets you do it. It is a topological 3D modelling tool from AMAXiMAL, now as TopMod 3D version 3, which runs in your web browser and on iPhone and iPad, and also works inside Rhino 8 as a plugin, with no installer and no payment for the free version. There is no payment for the free version, and you start from the official TopMod website.

This guide explains what TopMod is, what it can and cannot do, what your PC needs to run it, and how to start using it from the official website only. You will also get a first-use walkthrough that takes you from opening TopMod to a finished mesh in a few minutes. By the end, you should be able to open TopMod on Windows and use it in a real project.

TopMod is best for topological modelling, smooth organic meshes, and experimental 3D forms. Because the free version is free and legitimate, you do not need a cracked copy or an unknown download site. The official website is the only place to use it, and the free version is a real, permanent version, not a short trial.

What Is TopMod?

TopMod is a free browser-based 3D modelling tool that you use on your PC for building smooth, organic meshes. In simple terms, it is a program that opens in your web browser, where you start with a simple mesh, such as a cube or a sphere, and use topological operations to split, merge, smooth and reshape it into complex forms, like sculpting with mathematics. You can also use templates, export your mesh, and open your projects on iPhone and iPad.

What makes TopMod useful is its approach and its reach. Topological modelling lets you create forms that are hard to build with ordinary box modelling, and because version 3 runs in the browser, you can use it on any PC without installing anything, while the classic TopMod 2.0 and 2.5 desktop versions remain free for non-commercial use. The source code is also open on GitHub. Two honest notes: TopMod 3D version 3 is a web tool and an iPad and Rhino 8 plugin, not a standalone Windows desktop app, so you need an internet connection and a modern browser; and the classic desktop version is a legacy program from Texas A&M University, so it suits experimental modelling better than production pipelines.

Key Features

Topological modelling: Topological modelling lets you split, merge and smooth meshes into complex organic forms.
Runs in your browser: TopMod 3D version 3 runs in any modern web browser, with nothing to install.
iPhone and iPad apps: TopMod 3D version 3 also runs on iPhone and iPad, so you can model on the go.
Rhino 8 plugin: TopMod 3D version 3 works inside Rhino 8 as a plugin, for professional workflows.
Mesh export: Mesh export lets you take your models into other 3D programs and 3D printers.
Open source: The source code is open on GitHub, so the project is free and transparent.
Free for non-commercial use: The classic TopMod 2.0 and 2.5 desktop versions are free for non-commercial use.
Free version, no install: The free version costs nothing and runs in any modern browser, with nothing to install.

System Requirements

Operating System: Windows 10 or Windows 11, 64-bit
Browser: A modern browser such as Chrome, Edge or Firefox, with WebGL enabled
Processor: A modern dual-core processor or better
RAM: At least 4 GB of RAM for basic use
Storage: Almost no disk space needed, because TopMod 3D runs in your browser
Other: A stable internet connection, which TopMod 3D needs at all times, and a mouse for working in 3D

These are practical, modern Windows guidelines, not a word-for-word copy of an official specification table. The most important point is simple: TopMod is designed for normal Windows PCs, and a modest modern computer is enough to start.

How to Download TopMod (Official Method)

The only safe place to use TopMod is the official website. Do not download it from random file mirrors or “free download” portals, because the current version runs in the browser and there is no official installer to download, and those copies may be bundled with unwanted software. The official site is the source of truth for the current version.

Official download link: https://www.amaximal.com/topmod

On the official TopMod website, open TopMod 3D version 3 in your browser. There is no installer to download and no setup file for Windows: you open the website, launch TopMod 3D, and you are modelling. There is no payment for the free version. If a site offers you a TopMod installer to download, or a cracked version of it, leave that site and return to the official TopMod page.

Step-by-Step Installation

TopMod 3D runs entirely in your browser, so these steps take you from opening the website to your first mesh. Work carefully through them in order, and remember that version 3 is a web tool, not a standalone Windows app, so you need an internet connection and a modern browser.

Open the official TopMod website — Open https://www.amaximal.com/topmod in your browser.
Launch TopMod 3D — Click to launch TopMod 3D version 3 in your browser. No account or download is needed.
Wait for the editor to load — Wait for the TopMod 3D editor to load in the browser and confirm the 3D viewport appears.
Start a new project — Create a new project and give it a name, such as My First Mesh.
Choose a starting mesh — Choose a starting mesh, such as a cube or a sphere, to begin modelling.
Try a topological operation — Try a topological operation, such as splitting a face, to see how the mesh changes.
Save your project — Save your project, so you can open it again and keep working on it.

Tip: TopMod 3D version 3 runs in your browser, so if the editor will not load, check that your browser is up to date and that WebGL is enabled. If a page offers you a TopMod installer to download, do not use it, because the current version has no installer.

How to Build Your First Mesh with TopMod

This walkthrough is a simple first project. It is not a full course, but it will help you see TopMod working on a real project and learn its main tools.

Open TopMod 3D in your browser — Open https://www.amaximal.com/topmod and launch TopMod 3D version 3.
Start with a cube — Choose a cube as your starting mesh.
Split a face — Use a topological operation to split a face of the cube.
Smooth the mesh — Smooth the mesh, so the sharp cube starts to look organic.
Add more detail — Split and smooth a few more faces, so the form grows more complex.
Export the mesh — Export the finished mesh, so you can use it in another 3D program or print it.
Save your project — Save the project, so you can open it again and keep modelling.

Is TopMod Free?

TopMod 3D version 3 is free from AMAXiMAL. You use it from the official website, in your browser, without paying and without a time limit. There is no paid edition of the free web version itself. Be aware of two honest limits: version 3 is a web tool and an iPad and Rhino 8 plugin, not a standalone Windows desktop app, so you need an internet connection and a modern browser; and the classic desktop versions, TopMod 2.0 and 2.5, are free for non-commercial use only, and are legacy programs.

That free status is important for this guide. All the steps here use the official download only, and they do not involve cracks, activators or licence keys. If you ever see a site offering a paid or cracked version of the free program, treat it as unsafe and return to the official site.
