In order to keep the sketches as simple as possible, a maximum number of functions must be applied at the Bodies level. To learn more about these recommendations and obligations, consult the document below.

At CERN, sketches have to be set as "positioned". To learn more about these practices, please consult this document.

In a sketch, the construction elements must never be hidden. These elements are necessary to the comprehension of the sketch and of its constraints system. In this document, you will find more about these practices at CERN.

To avoid confusion in big assemblies, the reference planes, sketches, and construction elements must be hidden or if they need to remain visible, they must be renamed accordingly. This document shows the practices used at CERN.

All the geometrical elements of a sketch must be ISO-constrained. In this document you will learn more about the constraint practices at CERN.
