CadQuery is an intuitive, easy-to-use language for building parametric 3D CAD models. It has several goals: - * Build models with scripts that are as close as possible to how you'd describe the object to a human. - - * Create parametric models that can be very easily customized by end users - - * Output high quality CAD formats like STEP and AMF in addition to traditional STL - - * Provide a non-proprietary, plain text model format that can be edited and executed with only a web browser +* Build models with scripts that are as close as possible to how you'd describe the object to a human. +* Create parametric models that can be very easily customized by end users +* Output high quality CAD formats like STEP and AMF in addition to traditional STL +* Provide a non-proprietary, plain text model format that can be edited and executed with only a web browser Where does the name CadQuery come from? -=============================== +======================================== CadQuery is inspired by ( `jQuery `_ ), a popular framework that revolutionized web development involving javascript. @@ -25,11 +22,9 @@ revolutionized web development involving javascript.
