Description
This Surface Modeling Processes course covers the process of how to create freeform parts that update reliably and shift smoothly to the manufacturing application. As a second tier course, Surface Modeling Workflows builds on the tools you deployed as a result of attending the NX CAD Fundamental Workflows course. The real-world experience of the CAM Logic instructors aids students in transferring knowledge gained through this single course to their job resulting in faster time to productivity.

Intended Audience
This course is for Engineers and designers that need to create, edit, and analyze curves and freeform shapes used in part design.

Expectations and Goals

  • Create splines and derived curves used in creating freeform features
  • Analyze curves and faces
  • Build primary surfaces using curves
  • Create freeform shapes by sweeping sections along curves
  • Create transition and blend shapes
  • Extend and offset surface geometry
  • Convert surfaces into solid models.
  • Add draft to molded and cast part models
  • Deform parts using Global Shaping

Prerequisite

Required courses:
• CAD Fundamental Processes
Or: CAD FastStart for Experienced 3D CAD Users
Or: Successful completion of Designing Parts in NX prerequisite assessment on the Learning Advantage (score >70%)
