Welcome to rattleCAD

rattleCAD is free and a openSource software project. rattleCAD supports bespoked bicycle frame builders with a fully parametric bicycle model inside. rattleCAD guides you through the design process by configure the base geometry before refining the bicycle frame itself. Based on this refinement rattleCAD creates workshop drawings including the main miters of round tubes and settings for different frame jigs. rattleCAD also provides a set of components to build a bicycle mockup and supports different export formats to print and reuse all drawings generated inside rattleCAD.
rattleCAD uses XML file format to store project information and SVG file format to represent single components to mockup your bicycle. This components library can be extended to your own needs.
