BIM data management · Visual 3D control · Model-based cost calculation

Fast. Simple. Customisable.

IFC quantity takeoff, digital cost estimation, and intelligent BIM data processing without the compromises.

Where plans are born of shared decisions.

One of the most important steps in a build is clarifying the brief. The architectural model, building elements, and expected costs can be presented in a clear, easy-to-follow way to clients, partner designers, engineers, and contractors — based on unified model data in IFC format. The same flow supports digital drawing processing and shared quantity schedule reviews.
If anything is unclear, it is much easier to discuss before construction begins.
This is not a mandatory step — simply an option that supports shared decisions.
The first step is to speak to an architect, who can turn ideas into a professional architectural model.

Visual 3D control

IFC model handling & structure

Select any building element directly in the 3D view, or find it through the structured element tree — either way, the panels around it update instantly. Properties, quantities, group assignments, and detail information all stay in sync with whatever you have selected. Nothing is isolated. Everything is connected.

Open details

Digital drawing processing keeps model-based checks and quantity schedule creation in one place, so review and decision-making stay aligned.

Need to focus on a single floor, a specific material, or just the concrete elements? Hide everything else, adjust transparency, cut a section on the model, or explode the assembly to see what's inside. Standard orthographic views — top, front, side — and a measurement tool help when precision matters.

When you find a view worth keeping, save it. Camera angle, hidden elements, section cuts, exploded state — all stored and recalled in one click. Useful for recurring reviews, client presentations, or simply picking up where you left off.

The underlying IFC data can be edited at the structure level without touching the geometry. The model stays intact. Your working data stays accurate.

Cost management

Quantities & costs

Building elements can be organised into groups, and each group can be linked to a cost item from a unit-rate database. There are no fixed formats — use your own database, build a project-specific catalogue, or import from an Excel file or another external database.

Open details

Quantity sources come directly from IFC data — metadata, properties, quantity data, or saved formulas — so the cost structure is built from the model and supports day-to-day construction cost estimation.

The Documents panel shows the full cost structure in one place: categories, groups, quantities, units, material and labour rates, and totals. Missing prices can be filtered instantly, rows are searchable, and selected cost items stay linked to the model and the other panels — so related data is always one click away.

The Schedules view helps you check which elements, fields, and formula results make up each quantity. When the estimate is ready, export it as a full project package in .qbim format or as a standard Excel file — clean, traceable, and ready for review. This also supports digital tender preparation with model-based documentation.

The tools you use every day

Small details, big impact

Small details that speed up everyday work. AutoQuantity links the right quantity sources as soon as a cost item is assigned — one less step in a process that repeats many times in every project. Cost databases can be imported, exported, and updated through Excel, so your own unit-rate catalogues stay open and reusable — not only inside the application.

The program can also be controlled with artificial intelligence in natural human language. The main integration is a Claude MCP connection (Claude Desktop is required). During work, processes can be memorised by saving Skills, so you can teach and personalise your own AI. To install it, download and install the MCPB file available in the settings downloads.

Shortcuts, layouts, searches, and favourite elements reduce the number of clicks needed for daily work. These are the details that turn the model, cost data, and project communication into one connected working environment, aligned with a BIM-based design support workflow.

Whitepaper

One of the most important steps in a building project is clarifying the idea. Before discussing quotes, contractors, or scheduling, it helps to see clearly what we actually want to build.

The designer plays a key role in this process. Working with a good architect can produce a plan that genuinely reflects the original vision, to everyone’s benefit.

Once the plan is ready, it is worth asking for the IFC version as well (and although the architect is no doubt excellent, we still hope the plans were not made in Windows Paint).

An .ifc file is an industry standard that allows the plan to be reviewed and processed digitally. This software is a free alternative built on open formats. It is designed to let you review plans and models in a comfortable, structured way — on your own or together with the designer. If something is unclear, it is easier to discuss. If everything is in order, the system also allows digitally certified quote requests for construction work.

This is not a mandatory step, only an option. A tool to support decision-making — nothing more, nothing less.

The model can be shared freely and used in other systems, because it is not a closed solution. IFC-based workflows provide transparency.

Even so, the first step is still a good architect. Unfortunately, I cannot be that architect — I am a structural engineer. I simply do not have the professional licence to advise on where a window should go.
