Construction of Railcar
Using the Loft feature to create the cockpit of the car
Using the Extruded Cut feature to create hole for CO₂ cartridge and using Extruded Boss/Base to create rear fenders
Finished railcar body
Railcar fully assembled (added axles, washers, rims, tires, cartridge, and decals)
Railcar Assembly drawing
Flow simulation on right half of Railcar Assembly

The Design (Custom Car- VW Tiguan 2013)
Beginning of construction - using reference photos
Using Extruded Cut to create general form/shape of car
Result of previous image
Using Offset From Surface Extruded Cut to add details to front of car
Adding door details to car using Sketch and Extruded Cut
After adding details, colors, and decals (final car body)
Car fully assembled (later changed rear wheels to smaller wheels to minimize lift)
Surface Plot for assembly with larger wheels
Air flow simulation arrows (larger rear wheels)
After removing the large rear wheels and replacing with smaller wheels to minimize lift
