AutoCAD Training Overview
This course focuses on the creation of complex geometry that cannot easily be created using solid features. Surface Design provides users with a basic understanding of surface modeling styles and extensive exercises to practice the new functionality used to create complex geometry.
AutoCAD Training Topics
- Surface basics
- Curve network
- Creating simple surfaces
- Surface operations and analysis tools
- Creating surfaces from boundaries
- Curvature continuous surfaces
- Advanced swept surfaces
- Advanced surface options (blend section, blend between surfaces, blend tangent to surfaces)
- Offset surfaces
- Free form surfaces
- Importing IGES
AutoCAD Training Prerequisites
Pro/ENGINEER: Introduction to Solid Modeling I & II, Pro/ENGINEER: Advanced Part Design, and Pro/ENGINEER: Core Update, 2001 to Wildfire 2.0 or equivalent Wildfire experience.
