You can model almost any form imaginable with AutoCAD's surface toolset. In this project-based course, Scott Onstott teaches you all the techniques required to solve complex modeling challenges in AutoCAD, while focusing on an innovative ebike design. Learn to create each 3D component of the bicycle model, including its frame, belt-tensioner mechanism, drivetrain, electric-assist power components, brakes, wheels, axels, hubs, spokes, handlebars, and even the bicycle seat. The techniques (which can be applied to other mechanical models) cover extruding profiles, lofting 2D cross sections, revolving profiles around an axis, filleting edges, smoothing meshes into organic forms, and sculpting complex NURBS surfaces.
Topics include:
- Creating layers for 3D modeling
- Extracting isolines
- Trimming and extending surfaces
- Extruding 2D curves into 3D surfaces
- Lofting cross sections
- Converting solids into surfaces
- Sculpting watertight surfaces into solids
- Sweeping and sculpting
- Revolving boundaries to create surfaces
- Welding objects together with Fillet Edge
- Rebuilding NURBS surfaces
- Offsetting a surface
