BIM vs. CAD: Which Is More Practical for Information Transmission?

After years of development, Weidi software can generate 3D models based on pre-designed information. However, these models serve only as visual representations and do not contain detailed design information. They cannot be directly handed over to construction teams for execution. Detailed parameters for each component still need to be presented through 2D drawings, clearly showing the three views and material specifications of each structural element before submission to the construction team.

This approach results in a vast amount of information that must be transmitted to complete a project, leading to a large variety and volume of drawings. During the transmission process, there is a significant risk of information loss or incomplete representation, which severely reduces the overall efficiency of information exchange. These limitations in transferring information from design to construction pose hidden risks during project implementation, potentially causing unexpected losses.

BIM Q&A | Which is more practical, BIM or CAD? Comparison of Information Transmission Functions between BIM and CAD

BIM technology, as an information carrier, integrates all data from various construction disciplines into a single model, significantly reducing the volume of surface-level information. BIM models contain comprehensive information, effectively eliminating data omissions and unclear detail representations during transmission. This greatly enhances the completeness and efficiency of information exchange.

Furthermore, by reducing the amount of surface-level data, designers can significantly cut down on the number of drawings produced. This reduction allows designers to spend less time creating design documents within the same design cycle, freeing them from tedious drafting tasks. As a result, they can focus more on optimizing and improving the efficiency of the design itself.
