Most of the time spent on work planning is lost during the manual conversion of a 3D design into production-ready documents: cutting lists, material lists, and NC codes. This is especially true in interior construction work planning, where every project is unique and custom work is the norm. In this article, we answer the most frequently asked questions about time wasted in work planning and how to address this issue systematically.

Which steps in work planning take the most time?

The most time-consuming steps in work planning are manually creating cutting lists and purchase lists, calculating material optimization, and generating NC codes for the machine. In interior construction, this is further compounded by drawings for assembly and client presentations, which must be created anew for each project.

In practice, we see that work planners spend a large part of their day on tasks that are, in principle, repeatable. For example:

• Manually transferring measurements from a design drawing to a spreadsheet
• Compiling bills of materials for each component
• Calculating the most efficient way to cut sheets
• Creating or modifying NC programs for CNC machines
• Checking for and correcting errors caused by manual retyping

Not only do all these steps take time, but they are also prone to errors. A single typo in a dimension list can result in incorrectly cut materials, rework, and delivery delays.

Why does it take so long to convert a design into production-ready documents?

The process of converting a design into production-ready documents takes so long because, in traditional workflows, there is no direct link between the 3D model and the production output. Each step requires manual input, which means information must be re-entered into different systems or files.

In many companies in the manufacturing industry, designers work in a CAD program, while the production planner then manually transfers the data to Excel, an ERP system, or a separate CAM program. This leads to what is known as an “information gap”: the data from the design becomes disconnected from the production environment.

The consequences of this approach include:

• Duplicate work with every design change
• Higher risk of errors due to manual entry
• Longer turnaround times per project
• Less capacity for new orders

What is the difference between manual and automated work preparation?

In manual work planning, the work planner creates all production documents independently, separate from the CAD design. In automated work planning, the software generates all necessary output directly from the 3D model, without the need for manual input.

The difference lies not only in speed, but also in reliability. In an automated process, the information in the design is always the single source of truth. If you adjust a dimension in the model, all lists and codes are automatically updated. In a manual process, the work planner must make that change in multiple documents, with all the risks that entails.

For companies in the interior construction industry, where every project is different and clients frequently request changes, this difference is enormous. Automated work planning makes it possible to respond quickly to changes without having to redo the entire administrative process.

How can CAD software automate the work planning process?

CAD software can automatically handle work planning by linking the 3D model to an integrated output engine that extracts all production data directly from the design. Once the design is complete, the software generates all necessary parts lists, optimizations, and machine codes in a single step.

The key here is that the CAD software is not just a drawing tool, but also understands the manufacturing process. Components in the model are recognized as specific materials, dimensions are automatically extracted, and connections are correctly interpreted for manufacturing.

This works best when the software is specifically designed for the industry. In the interior construction industry, there are CAD packages that understand how a cabinet component works, what operations are required, and how that should be translated into machine instructions. That’s what sets them apart from generic CAD tools that lack this kind of domain knowledge.

What kind of output does CAD software automatically generate for manufacturing?

Modern CAD software for the manufacturing industry automatically generates cutting lists, bill of materials, sheet metal optimization, reports, and NC codes for CNC machines. All of these documents are created directly from the 3D model, without any manual intervention.

Specifically, this involves the following types of output:

• Cutting lists: an overview of all parts to be cut, including exact dimensions and material specifications
• Purchase lists: a structured overview of all required materials and quantities
• Sheet optimization: automatic calculation of the most efficient cutting patterns to minimize material waste
• Reports: project-specific documentation for internal use or client communication
• NC codes: machine instructions that can be sent directly to CNC machines

Because all of this output comes from the same source, the documents are always consistent with one another. There is no risk that the cutting list will differ from the parts list or that the NC code will be based on an outdated version of the design.

How fast is the work planning process with integrated CAD and ERP software?

With integrated CAD and ERP software, the time required for work planning on a standard project can be reduced from hours to minutes. The integration between design and business processes ensures that production orders, material reservations, and schedules are automatically generated as soon as the design is approved.

In practice, this means that a production planner no longer has to switch between separate systems. The design in the CAD software is directly linked to the ERP platform, ensuring that order information, inventory management, and production planning are always up to date. This not only shortens lead times but also provides greater insight into the status of ongoing projects.

For companies that are growing and want to handle more projects at the same time, this integration is not a luxury but a necessity. Without an automated integration, the workload associated with project planning grows along with the number of projects, leading to a bottleneck that hinders growth.
