Top 5 SketchUp Extensions for Contractors

If you use SketchUp regularly, you know the base tools only get you so far. The right plugins change how fast you work and what you can deliver.

Here's what actually makes a difference.

1/ Estimation & Takeoffs

Quantifier Pro

Calculates instant quantity and cost reports (area, volume, weight, length) directly from your model geometry.

Why it matters: It removes the manual spreadsheet work. You can assign cost data to layers or specific materials, meaning your estimate updates automatically as you change the design. The "Cost Inspector" tool lets you verify specific object costs without running a full report.

Best for: Rapid cost estimation and material takeoffs during the design phase.

PlusDesignBuild

A full BIM-for-SketchUp solution that handles everything from parametric modeling to Bills of Quantities (BOQ) and purchase orders.

Why it matters: It connects design to construction. It doesn't just count items; it understands construction logic (e.g., automatically adding studs, plates, and headers when you draw a wall). It bridges the gap between a pretty picture and a buildable project.

Best for: Design-build firms needing a complete workflow from concept to ordering materials.

2/ Framing & Structural Detail

Profile Builder 3

Generates smart, parametric objects (like walls, railings, and framing) that follow a path and can be edited non-destructively.

Why it matters: Native SketchUp "Follow Me" geometry is dead once created. Profile Builder objects remain editable—you can change a wall height or railing style in seconds without redrawing. The "Auto-Assemble" feature creates complex assemblies (like a framed wall with cladding) instantly.

Best for: Modeling repetitive structural elements like framing, piping, and fences.

Medeek Wall / Truss / Foundation

A suite of engineering-focused extensions that automate the creation of highly detailed 3D framing and foundation assemblies.

Why it matters: It provides engineering-level accuracy. Unlike generic modeling, Medeek calculates accurate stud layouts, headers, and truss engineering data, ensuring your model reflects actual construction standards.

Best for: Detailed structural modeling and generating precise framing plans.

3/ Workshop & Fabrication

OpenCutList

Generates professional cut lists, cutting diagrams, and labels for timber, sheet goods, and dimensional lumber.

Why it matters: It optimizes material usage. The plugin analyzes your components and calculates the most efficient cutting layout to minimize waste. It handles grain direction and kerf thickness, which native SketchUp ignores.

Best for: Cabinetry, joinery, and detailed carpentry work.

4/ Renovation & As-Builts

Undet

Imports and processes point cloud data directly inside SketchUp for accurate as-built modeling.

Why it matters: It eliminates guessing. For renovation projects, you can model directly over scan data to ensure walls, pipes, and structures are exactly where they exist in reality, not just where the old plans say they are.

Best for: Renovation contractors and retrofit projects requiring high precision.

5/ Construction Documentation

ConDoc Tools

Automates the creation of 2D construction documents (plans, elevations, sections) and organizes your model for LayOut.

Why it matters: It standardizes your output. Instead of manually managing hundreds of layers and scenes, ConDoc provides a rigorous system to instantly generate permit-ready drawings from your 3D model.

Best for: Moving from a 3D concept to a printable set of construction drawings.

Choosing what fits your work

Not every plugin makes sense for every project. Match tools to your actual bottlenecks, not feature lists.

Start with one or two that address your most frequent friction points. Add more as workflows evolve.

Bonus: Speed up rendering without leaving your workflow

If rendering is your bottleneck, Rendair handles visualization faster than most plugins can process.

Upload your SketchUp exports, get presentation-ready renders in minutes. No new software to learn, no render farm setup.
