3D Configurator for Custom Pergolas: No More Blind Quotes

A customer describes their custom pergola. A hand-drawn sketch, three back-and-forth emails or messages to pin down the exact dimensions, and a quote that goes out hoping it still matches what the customer had in mind. If you manufacture modular custom products (pergolas, carports, wood structures, matching furniture), this scene is familiar.

A modular 3D configurator is a tool that replaces that sketch with a guided online journey: the customer adjusts the dimensions, materials and options of their pergola or carport themselves, and at each step only sees the combinations your workshop can actually produce. This is what 3DVue builds for manufacturers of custom wood structures.

The problem: a quote that goes out... maybe

Modular custom manufacturing has a structural flaw: every project is different, yet pricing still relies on generic tools (sketches, spreadsheets, phone calls). The result costs you on several levels:

• Sales time: several exchanges before getting reliable dimensions and a priced quote.
• Risk of error: a measurement misheard on the phone becomes a wrong plan, discovered too late.
• Conversion rate: the customer waits, hesitates, and sometimes goes to a competitor who responds faster. In France, according to CAPEB (the French construction trade body), a project owner gets three different quotes on average before deciding: the first to respond has a real edge.
• Load on the design office: redrawing by hand a project that actually follows assembly rules known in advance.

None of this is a team problem. It's a tooling problem.

The principle: a guided configurator, not a free-form plan

A classic 3D planner (CAD-type) gives the user a free-form workspace: you still need to know how to use it to get a usable result. 3DVue's modular 3D configurator flips that logic. The customer moves through a guided journey, step by step: dimensions, then materials, then options. At each step, they only see what your workshop can actually produce.

Modules, dimensions, materials: what gets configured

Technically, it relies on a grid of standard modules (for example 1.2 m-wide modules for a pergola range), adjustable in width and depth within the limits you set. The customer then picks the materials and finishes available for their range, then the options: railings, stairs, privacy panels. At each step, the 3D render updates instantly, from every angle.

Only the combinations your workshop can actually produce

This is what changes everything compared to a paper quote. The compatibility rules (minimum and maximum dimensions, mutually exclusive options, materials available per range) are defined with you once, at integration time. Once these rules are in place, it becomes impossible for the customer to configure something you couldn't manufacture. Zero impossible combinations surfacing too late, once the quote is signed.

What this changes for you in practice

Three direct effects, once the configurator is in place on your range:

• On the sales side: the customer visualises the project and decides on their own, at any hour, without waiting for an appointment to get a first estimate.
• On the design office side: every order arrives with exact digital dimensions. No more reconstructing a plan from a sketch or a phone conversation.
• On the production side: what the customer validated in 3D is exactly what goes into manufacturing, since no incompatible combination was ever offered.

This matches a study published in Computers in Industry (Haug, Shafiee & Hvam, 2019) on engineer-to-order companies: adopting a product configurator is associated with higher specification quality, fewer errors, and faster, more accurate quotes.

Before / after

Not just pergolas

The principle applies to any modular custom product: pergolas, carports, wood structures, conservatories, garden sheds, gates, fencing, railings, but also matching furniture like benches or slatted screens. The only condition is having identifiable assembly rules, even complex ones. The more structured your range, the more precise the modular configurator is.

Frequently asked questions

Does this configurator replace my design office?

No. The configurator frames the possible options and passes exact dimensions to production, but structural calculations, wind resistance or local codes remain your design office's responsibility. What you gain is a reliable starting point instead of a sketch to redo for every project.

What types of products can be configured with this system?

Any modular product with identifiable assembly rules: pergolas, carports, wood structures, garden sheds, conservatories, gates, fencing, railings, but also matching furniture like benches or slatted screens. The principle stays the same: a grid of standard modules and dimensions adjustable within the limits your workshop masters.

How does the configurator avoid combinations that are impossible to produce?

The compatibility rules (minimum and maximum dimensions, mutually exclusive options, materials available per range) are defined with you at integration time. Once these rules are set, the customer simply cannot configure something your workshop can't manufacture.

Can the customer really configure it alone, without making mistakes?

Yes, that's the whole point compared to a classic CAD planner: the journey is guided step by step (dimensions, then materials, then options), with no open-ended screen where you'd have to guess what to do. It works from a phone, with no software to install.

What do I actually receive at the end of a configuration?

The exact references and dimensions of every part, ready to go into production, along with the 3D render validated by the customer. No more redrawing a plan by hand from a sketch or a phone call.

How long does it take to set up a configurator for my range?

It depends on the complexity of your parts catalogue and the number of assembly rules to define. Expect several weeks for a first modular range. We can show you a demo on an example close to your products to precisely assess the effort before you commit.

Conclusion

A blind quote isn't an inevitable part of modular custom manufacturing, it's a consequence of not having the right tool. By giving the customer a guided journey where only feasible combinations are offered, the 3D configurator turns an artisanal process (sketches, back-and-forth, redrawing) into a reliable digital flow, from the customer's first click to the dimensions that go into production.
