Automatically Generate CAD Drawings from Text and Documents: How AI Accelerates Design Using Business Logic
In many engineering departments, technical drawings are still largely created manually. Requirements are taken from order confirmations, emails, specifications, or brief descriptions, interpreted, and then translated into CAD models. This process is time-consuming, ties up skilled personnel, and is prone to errors.
At the same time, companies work with unique design logic, proprietary standards, and established block libraries that are often difficult to map in traditional automation solutions.
With ChatCAD, Kleen Software offers a solution that translates natural language and data-based inputs directly into technically accurate CAD drawings – automatically, precisely, and tailored to the company’s specific design logic.
The Challenge: Manual Design Despite a Digital Database
In many companies, the information needed for a drawing is already available – but not in a format that can be processed automatically. Dimensions, variants, component information, and configuration features are found in text documents, order confirmations, or internal descriptions. Nevertheless, the actual design process is often done manually.
Typical challenges in practice include:
- manual transfer of order and product information into CAD
- significant time expenditure for recurring drawing types
- reliance on experienced designers
- error-prone transfer of dimensions, variants, and parameters
- limited reusability of existing design logic
This results in a considerable amount of work, particularly for standardizable products and recurring variants, even though most of the rules are already known within the company.
Our Solution: ChatCAD
ChatCAD enables the fully automated generation of CAD drawings based on natural language, voice input, and structured documents.
Companies define their own design logic once (e.g. typical dimensions, standards, connection types, variants, or product-specific parameters). Based on this, the AI automatically generates appropriate drawings that align with the company’s own standards.
Existing block libraries and CAD logic can be directly integrated into the process. The result is not a generic AI drawing, but a CAD output that aligns with the company’s actual design practices.
Technological Foundations and How It Works
Natural Language and Voice-Based Input
ChatCAD processes free-form text and voice input directly. Users simply describe what needs to be designed, and the AI translates this information into a technically feasible CAD structure.
Data-Based Input from Documents
In addition to speech and text, structured or semi-structured content can also be used, such as order confirmations or technical descriptions. This allows existing documents to be integrated directly into the design process without manually transferring information.
Stored Business Logic
A key feature of ChatCAD is the ability to permanently store customer-specific design logic. This includes, among other things:
- Dimensions and dependencies
- Typical variants
- Component rules
- Connection types
- Product-related parameters
Based on this, the AI generates not just any drawing, but a drawing that complies with the company’s individual standards.
Integration of Existing Block Libraries
Existing block libraries and CAD logic can continue to be used. This avoids creating a siloed solution and instead serves as an extension of existing CAD processes.
Direct Integration into AutoCAD
The generated results are immediately visible in AutoCAD and can be further customized there as needed. ChatCAD complements existing design processes rather than replacing them.
Data Security and On-Premises Operation
Sensitive design data remains within your own infrastructure. ChatCAD can be operated on a local AI server or in a private server environment. This ensures that know-how, project information, and customer data remain protected while simultaneously meeting data protection and compliance requirements.
Application Examples and Customer Benefits
ChatCAD is particularly well-suited for companies that need to handle recurring drawing types, products with many variants, or standardized design rules.
Typical use cases include:
Automated drawing creation from order data
Information from order confirmations or product descriptions is used directly as input for drawing generation.
Faster design of recurring variants
Standardized products with fixed rulesets can be created much more efficiently without having to build each model manually.
Utilization of existing design standards
Company-specific rules and block libraries are preserved and systematically integrated into the AI-supported process.
Reducing the workload of experienced designers
Recurring routine tasks are automated, allowing specialists to focus more on complex special cases and development tasks.
Benefits at a Glance
- Fully automated generation of CAD drawings
- Processing of natural language, voice inputs, and documents
- Integration of customer-specific design logic
- Utilization of existing block libraries and CAD standards
- Direct visibility and editability in AutoCAD
- High data security through local or private infrastructure
- Less manual effort and reduced susceptibility to errors
Strategic Perspective
With ChatCAD, the design process shifts from manual modeling to rule-based, AI-supported drawing creation.
This is particularly relevant where companies already possess design knowledge that can be standardized but have previously been able to leverage it only through experienced employees or manual labor. ChatCAD helps systematically translate this knowledge into digital processes and generate scalable efficiency gains from it.
Conclusion
ChatCAD combines artificial intelligence with company-specific design logic and existing CAD practices. The solution enables the automated generation of technical drawings from speech, text, and documents—directly within AutoCAD and without compromising on standards, customizability, or data security.
For companies with recurring design patterns, a high proportion of variants, or manual routine processes, this provides a clear lever for greater efficiency, consistency, and speed in design.
