Solid Modelers

If you can afford one, a solid modeler is the best tool for designing a car. This software allows for parts and assemblies to be modeled, meaning the parts can be seen to work in concert before you create them physically. The parts are made up from basic shapes (Cube, sphere, cylinder, etc), which are combined via addition, subtraction and other means. The designer saves parts in a library and adds them as many times as needed. Designers can also purchase part model packs, which include things such as standard bolts, screws, nuts, etc.

Solid modelers add the capability of detecting if parts are not mating properly, and can often animate motion, allowing the designer to check that a suspension doesn't bind, for instance. Anyway, these are but a few of the products available. The focus is on PC/Windows applications, as is all software in this guide.

 

Autodesk Inventor Solid modelling software with an intuitive interface, and good feature set. www.autodesk.com
TurboCad Solid Modeler Low cost powerful solid modelling software. Probably the best value going. TurboCAD Solid Modeler More Info
TurboCad 3D Modeler A lower end version, very useful, and low cost www.turbocad.com
Solidworks Popular solid modeler with extensive features. Lots of 3rd party support for FEA and CFD "add-ons" www.solidworks.com
SDRC I-deas Series Solid modeling, sheet metal, mechanisms -- very powerful software in use by a number of racing teams. (~5000) www.sdrc.com
Autodesk Mechanical Desktop 4 Full featured solid modelling and drafting package. www.autodesk.com
CADKEY 99 Does a wide range of drawing 2D, 3D, Solid modeling, surface modeling. (~2000) www.cadkey.com
Unigraphics Solid Edge Another reputable solid modelling package.. This package should not be confused with the scaled down "Origin" version mentioned to the right.

www.solid-edge.com

Solid Edge Origin is available for free. Good to learn on, but complete car design is not possible. Click here to download.

 

Standard CAD Packages

The standard CAD packages are useful tools, but lack the part and assembly features of the solid modelling software. Still, they allow drafting precise designs, and as long as the designs can be co-ordinated properly, one can still use these packages for car design. You will also save a bunch of money.

 

AutoCAD LT A 2D CAD package from the industry standard Autodesk. Great features. AutoCAD LT 2002
AutoSketch 2D CAD. Good feature set. AutoSketch 7.0 More Info/BUY IT!
TurboCAD 2D/3D CAD software with great features and a low price
