In short, floor plan software is now an indispensable part of the modern design professional's toolkit. But with so many options on the market, which one should you choose?

The 7 Best Free Floor Plan Software Tools1. XTEN-AV X-DRAW

Our top pick for the best free floor plan software, especially for AV professionals, is XTEN-AV X-DRAW. This cloud-based platform is purpose-built for designing and documenting audiovisual systems, with a host of features that set it apart from generic CAD or drawing tools.

What makes X-DRAW so powerful?

First, it comes loaded with a massive library of AV-specific symbols, objects, and product models, all accurately scaled and data-rich. Place a speaker or display in your design, and X-DRAW automatically knows its dimensions, connectors, power requirements, and more.

Second, X-DRAW automates much of the busy work that usually slows down AV design. As you place devices in your floor plan, the software instantly generates rack elevations, cable schedules, signal flow diagrams, and bills of materials. If you move a speaker, its associated cabling and documentation update in real-time.

Third, X-DRAW is built for seamless collaboration. Multiple users can work on the same drawing simultaneously, with changes synced instantly. Granular permissions control who can edit, comment, or approve. And because everything is browser-based, your team can jump in from anywhere.

Other standout features include:

• Intelligent device suggestions and conflict warnings
• Automated drawing of cable routes and connection plates
• Instant 3D rendering and VR walkthroughs
• One-click generation of install guides and client proposals
• Deep integration with D-Tools and other AV platforms

While incredibly powerful, X-DRAW still manages to be intuitive, with a short learning curve even for AV design newcomers. Overall, it's simply the most comprehensive, automated, and AV-optimized floor plan solution on the market.

Pricing: Free for 1 project; paid plans from $45/month

Best for: AV system integrators, audiovisual consultants, home theater designers

2. SketchUp Free

For a versatile and beginner-friendly floor plan tool, it's hard to beat SketchUp Free. As a trimmed-down browser version of the popular 3D modeling software, SketchUp Free delivers a lot of power and functionality at no cost.

The key appeal of SketchUp is its ease of use. With a simple toolbar and intuitive click-and-drag modeling process, even total beginners can quickly mock up a basic 3D floor plan. Helpful guides automatically snap lines and objects to the proper axis and alignment.

That simplicity does come with some limitations. SketchUp Free has a smaller object library than many paid tools. Documentation is also limited—you won't get automated electrical/mechanical schematics. And the free version lacks some advanced features like terrain/topo modeling.

Still, as a quick and easy way to generate 3D floor plans and visualize designs, SketchUp Free is an excellent starting point, especially for students and solo designers. It's also a great tool for rapidly prototyping concepts before moving to dedicated AV software like X-DRAW.

Pricing: Free (paid plans add features)

Best for: Quick 3D models, basic floor plans, students, solo designers

3. Autodesk DWG TrueView

For a no-frills, 2D drafting tool, check out Autodesk DWG TrueView. This free viewer allows you to open, view, and print any DWG or DXF file—the standard formats for AutoCAD drawings.

While it lacks the 3D modeling and automation of other tools covered here, DWG TrueView is great for quickly viewing and marking up 2D floor plans. It's an efficient option if you simply need to review AutoCAD drawings created by others, add minor edits/comments, or output them for distribution.

The software preserves the scale and integrity of the original file, so you can trust that dimensions and layouts are accurate. You can also convert DWG files to PDFs for easier sharing with clients or contractors.

Pricing: Free

Best for: Viewing & marking up 2D AutoCAD files, quick PDF conversions

4. Sweet Home 3D

For home DIY-ers looking to model interiors and try out furniture layouts, Sweet Home 3D is a solid free option. This open-source software strikes a nice balance between ease of use and functionality.

You start in a simple 2D plan view, drawing walls and adding features like doors, windows, and stairs. A drag-and-drop library of furniture, appliances, and decor makes it easy to mock up complete rooms and experiment with different arrangements.

In the 3D view, you can do virtual walkthroughs to get a sense of the final space and even generate photorealistic images and videos with custom lighting and shadows. It's a handy way to preview how different materials and finishes will look.

While Sweet Home 3D can certainly be used to create basic floor plans from scratch, it's better suited to interior visualization, materials selection, and furniture layouts. It lacks the precision drafting tools and smart object libraries of software like X-DRAW or AutoCAD.

Pricing: Free (paid upgrade adds features)

Best for: Interior design, furniture layouts, home remodeling visualization

5. Floorplanner

Floorplanner is a web-based tool that offers a nice mix of 2D floor plan and 3D rendering functionality. With an intuitive, drag-and-drop interface, a huge library of furniture and fixtures, and nifty features like one-click room generators, it's a strong choice for quickly mocking up designs.

For 2D floor plans, you have access to all the essential drawing tools: dimension snaps, measurement overlays, custom labeling, and more. Switch to 3D mode and you can view your design from any angle or do a virtual walkthrough.

One standout feature is the ability to generate high-res, print-quality renderings of your 3D model, complete with realistic finishes and lighting. Floorplanner also makes it easy to share interactive floor plans via a link or embed them on your website.

While the free version limits you to one plan, it's a great way to try out the software. Paid versions remove the watermark and enable higher-quality exports, custom colors, and more.

Pricing: Free for 1 plan; paid plans from $5/month

Best for: Quick mockups, interior design, real estate listings

6. SmartDraw

More of a diagramming tool than a dedicated floor plan platform, SmartDraw nonetheless has some nice templates and features for creating basic 2D layouts. It's also one of the few tools that runs completely in your browser, with no downloads required.

SmartDraw's key selling point is the huge variety of templates and pre-drawn symbols, which span everything from office layouts to fire escape plans to crime scene investigations. For floor plans, you'll find pre-made room layouts, furniture, appliances, wiring/plumbing symbols, and more.

The drag-and-drop interface is straightforward, if a bit dated-looking. You can easily add, move, and align objects, then annotate them with custom measurements and labels. One nice touch is the automated dimensioning, which instantly calculates and displays room sizes as you draw.

SmartDraw is a decent option for cranking out simple 2D floor plans, but it lacks the precision drafting tools, 3D modeling, and advanced automation of more robust software. It's best suited for quick-and-dirty sketches or layouts where visual polish is less important.

Pricing: Free for 1 user

Best for: Basic 2D layouts, flowcharts, network diagrams, org charts

7. Roomle

Rounding out our list is Roomle, a 3D room planner aimed primarily at visualizing interior designs and layouts. With a slick, modern interface and a good selection of customizable furniture, it's a solid pick for exploring decor ideas and arrangements.
Roomle's editor is fully 3D, so you can view your room from any angle as you build. The catalog includes thousands of brand-name products, from sofas and tables to appliances and decor. You can even customize the colors and fabrics to match your style.

A particularly cool feature is the ability to upload a photo of your existing room and use it as a template for your 3D model. This makes it easier to experiment with new layouts and see how different pieces will fit in your space.

On the downside, Roomle is light on technical features. It doesn't generate detailed floor plans with precise measurements. Instead, the focus is more on visual inspiration and rough layouts.

Pricing: Free to try; paid plans for more features

Best for: Interior decorating, furniture layouts, room remodeling ideas

Case Studies

To see these floor plan tools in action, let's look at a couple of real-world case studies:
