+CadQuery is an intuitive, easy-to-use Python library 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, using a standard, already established programming language
+- 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

According to this technique, simple objects can be transformed and combined in order to create almost any complex model.
