This purpose driven CAD model is a current in progress project. It features mostly simple CAD techniques, but results in a fairly complex model. Detail and accuracy is paramount as this CAD model will eventually be completed and used to make fixtures and templates construct a full scale high performance car.
The Kingcat is a real turbine powered R/C model aircraft that is produced by Bob Violet Models. This models beautiful lines and unique profile have made it a favorite of mine for several years now. I decided that I wanted to make a 3D printed desk model of this jet. Using only a few photos of the real aircraft I recreated this model in AutoCAD. I started by creating a number of complex 2D shapes. Then using the extrude, revolve, loft, and fillet commands, I was able to complete the bulk of the 3D modeling.

This is a 1/10th scale 3D printable model of a "Wilderness Systems Tarpon 120" kayak. I modeled this kayak using only photographs for reference. This model features softer more organic contours and shapes. Utilizing tools such as the loft, sweep and fillet commands. The model was sliced into 2 section to fit my 3D printer and is seamlessly joined using 3 brass rods. Click "HERE" to See pictures of the printed model of this kayak on my 3D PRINTING page.
This wheel and tire assembly is part of my SCX10 R/C truck. This model was largely created by drawing 2D cross section profiles of the wheel, tire and foam core. Then using the revolve command to generate the 3D model. The tire tread was created by making a 3D model of just 1 tread then using the 360 array command to generate the rest of the treads. The remaining details were added by using simple extrude and subtract modeling methods.
This transmission is part of my SCX10 R/C truck. This assembly of smaller models was largely created using standard 2D and 3D modeling techniques and commands. The most unique part if this assembly from a CAD standpoint is the small green clutch spring shown in assembly set "D" this was created using a combination of the coil and sweep commands. Part "E" the gear cover also used a unique command called the Shell command, which will take a complex 3D solid and make it hollow, when you assign a wall thickness to it. This is a very useful tool when creating complex shapes that you know will later need to be hollowed out.
This front axle is another part of my SCX10 R/C truck. The axle-housing on this axle is hollow. But unlike the gear case on the transmission, the shell command is not the best way to hollow it out. Due to the need of the axle housing to mechanically support internal components, it cannot simply have one constant wall thickness. For this task it is best to create a 3D plug that is to be subtracted from the axle housing that mimics the internal components, plus any additional clearances that might be required.
This seat was created as part of a interior kit for one of my R/C snowcats. Copies of it have found their way into R/C Jeeps, trucks, and cars as well. We all sit on seats every day and often don't give much thought as to how complex an upholstered seats' geometry is. This seat is fairly complex but it is actually created with just five basic extruded shapes and some simple fillets.
