Thinking about users from outside Poland, I developed an updated version of the eBook SOLIDWORKS 2021 Part Modeling, Assemblies, and Drawings.
SOLIDWORKS 2021 eBook is intended for both beginners and advanced users. Provides clear directions step by step, how to make an element starting from scratch. More complex examples are discussed in each of the following sections, of which, at the end, you need to build the assembly and verify it.
The eBook also discusses drawings of parts and assemblies. The whole is complemented by a lot of tricks and tips to improve your work in SOLIDWORKS.
