Thank you for your continued support. We have an announcement from Arc System. We have updated the "Seki-san's Helpful Blog," where we post useful knowledge for everyone involved in the construction industry's estimation work! This time, the theme is about "cross-sectional drawings." Cross-sectional drawings play an important role in the design and construction of building projects. They contain the necessary information to ensure compliance with building codes, to construct each floor and room according to the design, and to connect these elements within the building. So, what specific information is included in cross-sectional drawings? This time, we will clearly explain the overview of cross-sectional drawings, how they differ from other drawings, how to write them, and key points to consider when creating them. <Content of the post> What is a cross-sectional drawing?

  • OTHER

Thank you for your continued support. This is a notice from Arc System. We have updated the "Seki-san's Useful Blog," where we post helpful knowledge for everyone involved in construction cost estimation! This time, the theme is about "Frame Diagrams." The design documents used in construction work are mainly classified into four types: "Structural Diagrams," "Architectural Diagrams," "Equipment Diagrams," and "Site Diagrams." These drawings are further divided into several categories, and construction work proceeds based on each of these drawings. The frame diagram is one of the drawings included in the structural diagrams. To understand the structure of a building, the frame diagram is essential. This time, we will focus on the frame diagram within the structural diagrams, explaining what a frame diagram is, how to read it, and the types of other structural diagrams in an easy-to-understand manner. <Content of the post> What is a frame diagram? Introduction to how to read it and types of structural diagrams - What is a frame diagram (jiku-gumi-zu)? - How to read a frame diagram - What other types of drawings are there besides frame diagrams? - Let's correctly understand the structure and framework by grasping how to read a frame diagram.
