© CADDi Inc. Mission 5 Unleash the potential of manufacturing We aim to create a society where everyone involved in manufacturing can fully realize their inherent potential. To achieve this, we will establish "new mechanisms" that transform the conventional wisdom of the industry. In the current manufacturing sector, a vast amount of potential remains untapped. Many are overwhelmed by estimation and management tasks, lacking sales capabilities, information, and networks. These constraints prevent them from showcasing their true development and technical abilities. By easing these restrictions, we can unlock the potential of each company, generating significant strength across the entire industry and enriching it. From small local factories to large, historically significant manufacturers, and newly established ventures—every manufacturing company can leverage its strengths to shine and create new value. We will continue to strive to carve out such a future.

© CADDi Inc. What is “CADDi”? 6 From CAD Directly The company name “CADDi” combines the meaning of “ordering directly from CAD” and “the desire to become an infrastructure that supports players in the manufacturing industry,” likened to a caddy in golf.

World's Largest Industry: Manufacturing 9 Infrastructure industries that support our daily lives The manufacturing industry is involved in all the things we need in our daily lives, including medicine, food, transportation, and communications. All kinds of things are produced by the hands of many people, including industrial machinery, machine tools, and processing companies. Smartphones consist of more than 1,000 components, including semiconductors, batteries, and displays Industrial Features

© CADDi Inc. 14 “Drawing” are the most important data in the manufacturing industry. We do not just store them, but utilize them as “assets” that will create value in the future. Drawing out what has been stored and creating value. CADDi Drawer” is a platform for this purpose. Drawing Drawer CADDi Drawer Application ①

© CADDi Inc. Information on Drawings and the Challenges of Analysis 15 Surface Roughness Indicates the smoothness of the finished product. Higher smoothness requirements lead to increased costs. Chamfering Refers to the process of beveling edges, which can be done at angles like 45° or using rounded methods.The choice of machinery impacts pricing and sourcing Geometric Tolerances Precision and allowable deviations of part shapes; smaller deviations make finding capable manufacturers harder. Symbols indicate specifications, and numbers show tolerance ranges. Hole (Φ) It may not be readable by third-party OCR Title Block There is a variety of information tied to the drawing. We want to get it in key/value pairs. Blanks Fairly sparse Handwritten Txt the inconsistency in style and legibility. Rotated Characters Characters rotated by 90° or presented vertically may not be read correctly. Dimensions Dimensions may be listed in both millimeters and inches It reflects similarity not just in appearance but also in the actual shape of the item.

© CADDi Inc. 17 CADDi Quote Application ② In the manufacturing industry, where costs account for 80% of total sales, the "quotation process" for determining prices is extremely important. However, until now, there has been a lack of significant innovation in this area, and many problems have been faced, such as the delegation of work to veteran employees and the tightening of workloads due to e-mail and fax-based implementation. “CADDi Quote" will greatly improve the quotation experience and create a cycle in which daily work becomes an asset.

Compounding Strategy As the number of applications grows by the dozens, it is necessary to organize the dependencies as a whole while growing each one. ● Assumption of 10x annual growth CADDi aims to change the world in the next 10-20 years time horizon. The angle of growth required is unprecedented in Japan. In development, we are forced to make difficult decisions on a daily basis on how much technical debt to tolerate and how much functionality to build in. Existence of the physical world The manufacturing industry is not completed in the digital world. How to seamlessly connect with the real world is an extremely challenging challenge from a data perspective. The number of stakeholders Manufacturing involves hundreds of people just to make one component.The requirements for certification/authorization and UI/UX are extremely complex and sophisticated. ● A wide variety of data We handle not only structured data, but also unstructured data such as drawings, product images, and documents.Engineers are tested on how to create customer value using a large volume and variety of data.

© CADDi Inc. Manufacturing Quality Making implicit knowledge explicit from drawings and documents to stabilize manufacturing quality. Quotation Recommended Suppliers for Quotation Supplier selection is often based on personal experience and judgment, leading to a subjective process. By selecting suppliers based on past quotation records, processing characteristics from drawings, and manufacturing performance data, we can ensure consistency and transparency, enabling efficient supplier selection and anticipating cost reductions and quality improvements. Future Vision and Research Development Themes 25 Data Related to Manufacturing Preventing risks during the design phase Digital tools for creating and editing 3D models and detailed design drawings CAD (3D) Design information expressed in 2D drawings, including product shape, dimensions, and materials. Drawings Numerical and categorical information managed in standardized formats, such as bills of materials (BOM) and inventory lists. Structured Data Text related to products, including specifications, manuals, and reports. Documents Drawing etc.. Quality Design Quotati on Order Receiv ed Order Place Product Design Preventing risks during the design phase Design reviews are conducted at each stage of design to verify and improve quality, functionality, and cost. By making information about related products and components easily accessible during design review preparation and execution, we can enhance review efficiency and reduce the risk of overlooking critical points. Ensuring manufacturing quality relies on the expertise of veterans and implicit knowledge from past transactions, which is often not clearly shared. By analyzing drawings and specifications to extract processing characteristics, we can identify critical points to watch during manufacturing, reducing risks and stabilizing/improving quality. ● Cost information ● Supplier information ● Customer Specification ● Issue History ● design philosophy / memo ● VA/VE Ideas Are there any issue that have occurred with similar products?
