Universal Selection Criteria and Pitfall Avoidance Guide
Selecting the right CAD software requires a methodical approach based on cross-verification from multiple sources. First, define your core workflow: is it primarily 2D drafting, 3D parametric modeling, complex surfacing, or BIM? This will immediately narrow the field. Second, rigorously evaluate the total cost of ownership, looking beyond the initial license fee to include subscription/annual costs, mandatory maintenance fees, training expenses, and potential hardware upgrade requirements. Third, verify interoperability needs by testing file import/export with key clients, partners, and manufacturing vendors; reliance on a single proprietary format can create long-term bottlenecks. Common pitfalls to avoid include opaque pricing models that hide costs for essential modules or render farms. Be wary of over-reliance on vendor marketing claims about "ease of use" or "revolutionary features"; always seek independent user reviews and, if possible, conduct a hands-on trial or proof-of-concept project. Another risk is inadequate technical support and training resources, which can severely hamper productivity post-purchase. Investigate the availability of local reseller support, official certification paths, and the vitality of user forums. Finally, ensure the software's system requirements are compatible with your existing IT infrastructure to avoid unexpected hardware investments. Reference can be made to official system requirement documents from vendors and benchmark reports from hardware review sites.
