This page contains the parts pipes, beam, channel, sheet metal, and support blocks. There are 2D and 3D drawings and models available for pratice.
While trying to model and draw in any 3D CAD modelling software, try to use different features instead of using the same feature/ command again and again. For example, Use a hole command instead of using a extrude cut or removing material using a normal sketch. Solidworks is one of the best when it comes to easy UI design which enables us to know the various features available and make use of it.
