BIM Q&A | Ideas for CATIA Modeling?
I have been working in automotive parts design for over two years since graduating. Over the past year, I have developed many products, yet I still feel I lack a clear and specific approach to CATIA modeling.
Currently, our company’s design department has more than 200 employees, each working on their own modeling projects. However, there are no established modeling standards—only design standards. As long as the final results meet requirements, everyone uses their own methods, exploring what they find most convenient.
My current approach is to start with the customer-provided A-surface to build the main structure, then add various features on top. After that, I thicken certain areas, apply drafts, and add fillets. However, this method involves a large and complex workload when making later modifications, often requiring multiple rounds of revisions. The review process is challenging, as supervisors frequently change their ideas, which causes me a lot of frustration.
Later, I obtained data from foreign companies and noticed they use Boolean operations and other advanced functions extensively. Their data is clean and organized, with a single solid entity and unified surfaces—all based on a common benchmark, using each other as references.
Now, I’m confused about which modeling approach is truly the best. I’m turning to Zhihu for advice from experienced professionals to help me, a novice designer, find a clearer path forward.
