AutoCAD: Advanced 3D Modeling

via LinkedIn Learning


Learn how to design surface, solid, and mesh models with AutoCAD. Discover how to solve complex modeling challenges as you focus on an innovative ebike design.


  • Design surface model with AutoCAD
  • What you should know
1. Get Set Up
  • Navigate in 3D space
  • Configure 3D workspaces
  • Configure options
  • Create layer and property filters for 3D modeling
2. Model the Bicycle Frame
  • Extrude and patch a surface
  • Manipulate the user coordinate system
  • Use Offset and regions to generate surfaces
  • Sweep a profile along a curved path
  • Extrude and trim surfaces
  • Revolve profiles
  • Extrude a profile along a curved path
  • Draft multiple cross sections
  • Loft surfaces from cross sections
  • Draw cross sections along a spline
  • Loft with the Path option
3. Create the Belt-Tensioning Mechanism
  • Adjust a lofted object's 3D form
  • Sculpt a solid out of watertight surfaces
  • Use Boolean operations on solid objects
  • Model a dropout to be sandwiched between plates
  • Model fasteners
  • Adjust and trim the bottom triangle
  • Mirror the frame and belt-tensioning components
4. Build the Drivetrain Components
  • Position cross-sectional drawings relative to a model
  • Remove unwanted volume with Subtract
  • Combine surface and solid modeling
  • Configure sketches of sprockets
  • Fillet edges and array sprocket components
  • Create the drive belt as a solid object
  • Duplicate and 3D rotate the sprocket
  • Revolve, extrude, and subtract objects
5. Model the Rear Brakes
  • Subobject editing and filleting edges
  • Use region editing techniques
  • Model fasteners that hold the rotor on the hub
  • Use Boundary to generate a profile
  • Create disk brake calipers welded onto the frame
6. Create the Rear Wheel
  • Revolve profiles and manipulate layers
  • Sweep a spoke along a 3D path
  • Use Array and Mirror to fill the rim with spokes
7. Make the Power Components
  • Build the drive unit using Extrude and Loft
  • Model the cranks using the solid tools and point filters
  • Smooth a mesh object
  • Tilt up and assemble extruded objects
  • Use 3D Align to align a pedal with crank
8. Model the Front End
  • Loft cross sections to create a complex form
  • Clean up 2D entities in preparation for 3D modeling
  • Revolve boundaries to create surfaces
  • Copy components from the rear to front axle
  • Model the front hub
  • Sweep spokes along 3D paths
  • Adjust the front axle, acorn nuts, and spacer
  • Copy and reposition the front brake calipers
  • Copy the rim and tire to the front
9. Create the Handlebars
  • Weld objects together with Fillet Edge
  • Extract isolines from surfaces to loft new surfaces
10. Form the Battery Compartment
  • Sculpt a NURBS surface using its CVs
  • Loft between NURBS surfaces
11. Make the Seat
  • Extrude and subtract regions
  • Loft and revolve profiles
  • Create a 3D path from the intersection of two extrusions
  • Rebuild NURBS surface to optimize its control vertices
  • Move CVs in multiple viewports
  • Offset a surface and round its hard edges
  • Clean up and visualize the entire bicycle
  • Next steps
