# DesignSpark Mechanical for PC: How to Download & Install on Windows
## Introduction
If you want to design mechanical parts in 3D without paying for a CAD licence, DesignSpark Mechanical is the free program that lets you do it. It is a free direct-modelling 3D CAD program from RS Components, built on the SpaceClaim engine, with push-pull modelling, a library of more than 75,000 RS product models, and a free Explorer plan that covers basic direct modelling. There is no payment for the Explorer plan, and the download from the official DesignSpark site is the complete free version.
This guide explains what DesignSpark Mechanical is, what it can and cannot do, what your PC needs to run it, and how to download and install it from the official website only. You will also get a first-use walkthrough that takes you from installation to a finished part in a few minutes. By the end, you should be able to install DesignSpark Mechanical on Windows and use it in a real project.
DesignSpark Mechanical is best for direct modelling, quick mechanical parts, and learning 3D CAD without a licence fee. Because the Explorer plan is free and legitimate, you do not need a cracked copy or an unknown download site. The official website provides the installer, and the free plan is a real, permanent version, not a short trial.
## What Is DesignSpark Mechanical?
DesignSpark Mechanical is a free 3D CAD program that you install on your Windows PC and use to design parts and models. In simple terms, it is a program where you sketch a shape, push and pull it into 3D, cut holes in it and combine it with other parts: you draw a profile, pull it into a solid, and refine it until you have a finished part, ready to export or 3D print. You open it, sketch, and build.
What makes DesignSpark Mechanical useful is its direct modelling and its parts library. Because it is direct modelling, you edit the shape itself rather than a history tree, so changes are fast and intuitive, and because it is from RS Components, it includes a library of more than 75,000 product models, with RS part codes for bills of materials and quotes. It also exports to common CAD formats. Three honest notes: DesignSpark Mechanical needs a free DesignSpark account to download and use; the free Explorer plan covers basic direct modelling and bills of materials, while engineering drawings and advanced import and export need the paid Creator or Engineer plans; and it is Windows-only, with no Mac or Linux version.
## Key Features
– **Direct push-pull modelling:** Direct push-pull modelling lets you edit the shape itself, with no history tree to manage.
– **RS product model library:** A library of more than 75,000 RS product models, with part codes for bills of materials.
– **Sketch-based design:** Sketch-based design turns 2D profiles into 3D solids by pulling, revolving and sweeping.
– **Bill of materials:** A bill of materials tool lists the parts in your design for quotes and ordering.
– **Common CAD export:** Common CAD export formats let you share models with other CAD programs.
– **Free Explorer plan:** A free Explorer plan covers basic direct modelling with no hidden fees.
– **Windows native:** A native Windows program that installs and runs like any other desktop CAD tool.
– **Easy to learn:** An easy-to-learn interface makes it a good first CAD program for makers and students.
## System Requirements
– **Operating System:** Windows 10 or Windows 11, 64-bit
– **Processor:** A modern dual-core processor or better
– **RAM:** At least 4 GB of RAM for basic use, 8 GB or more for larger models
– **Storage:** Around 1 GB of free disk space for the download and program files
– **Graphics:** An integrated or dedicated graphics card with at least 1 GB of graphics memory, DirectX 11 and OpenGL 4.5 support
– **Other:** A stable internet connection for the download and account registration, 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: DesignSpark Mechanical is designed for normal Windows PCs, and a modest modern computer is enough to start.
## How to Download DesignSpark Mechanical (Official Method)
The only safe place to download DesignSpark Mechanical is the official website. Do not download it from random file mirrors or “free download” portals, because those copies may be outdated or bundled with unwanted software. The official site is the source of truth for the current version.

## How to Model Your First Part with DesignSpark Mechanical
This walkthrough is a simple first project. It is not a full course, but it will help you see DesignSpark Mechanical working on a real project and learn its main tools.
1. **Start a new design** — Open DesignSpark Mechanical and start a new design.
2. **Draw a 2D sketch** — Draw a simple 2D profile, such as a rectangle, on the sketch plane.
3. **Pull the sketch into a solid** — Pull the sketch into a 3D solid, so you have your first part.
4. **Cut a hole in the part** — Draw a circle on the top face and cut it through the part, so you have a hole.
5. **Pull a face to change the shape** — Pull a face of the part to change its shape, to see direct modelling in action.
6. **Add a part from the library** — Add a part from the RS product library, such as a screw, to your design.
7. **Save and export your part** — Save the design, then export it as an STL file, so you can 3D print it.
## Is DesignSpark Mechanical Free?
DesignSpark Mechanical is freeware from RS Components, with a free Explorer plan. You download it from the official DesignSpark site, install it, and use it without paying and without a time limit. The free Explorer plan covers basic direct modelling and bill of materials generation. Be aware of three honest limits: it needs a free DesignSpark account to download and to sign in; engineering drawings and advanced import and export need the paid Creator or Engineer plans, which offer 7-day free trials; and it is Windows-only, with no Mac or Linux version.
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.
## Frequently Asked Questions
**Is DesignSpark Mechanical safe to download?**
Yes, when you download it from the official website only. The official installer is the version made by the developer. Avoid third-party sites that bundle extra software or ask for payment for a free program.
**Does DesignSpark Mechanical work on my Windows PC?**
Yes, in most cases. DesignSpark Mechanical runs on Windows 10 and 11 (64-bit), and the system requirements above cover a normal modern PC. Check the official site for the exact current version if your PC is older.
**Is DesignSpark Mechanical really free, or will it stop working?**
The free Explorer plan described in this guide is not a short trial. It stays usable after installation. Engineering drawings and advanced features need the paid Creator or Engineer plans.
**Do I need a powerful PC to run DesignSpark Mechanical?**
No, not for basic use. A modern Windows 10 or 11 PC with 4 GB of RAM or more can run it for simple projects. Larger projects with many objects and effects will benefit from more RAM and a faster processor, but you can start and learn on a normal home PC.
