Longview Advisors recently published the results from their survey on “3D collaboration and Interoperability“.  Some of the interesting comments:

“SolidWorks and Pro/ENGINEER are the most often used primary CAD systems among survey respondents… CATIA and NX, while still leading in the very largest, are not being selected by the mid market or small firms most represented in our survey”

[…]

“Only 16% said that 3D CAD is used in production/shop floor operations”

[…]

“65% of respondents are using the CAD system of their own choice, either by receiving neutral file formats or by converting between product-specific file formats.”
