Blender is a great, free - polygon / subdivision 3D drawing program / physics simulator, where almost everything can be accessed / programmed via a simple Python API. For advanced "organic" shape design it is superior to SolidWorks. In Blender you can import STL parts designed in SolidWorks - however, SolidWorks will normally produce crappy polygons which may be difficult to further modify in Blender. On the other side, a part designed in Blender can often be converted to NURBS by using PowerSurfacing, a SolidWork plug-in, and then further modified in Solidworks. Blender is not a parameter based modelling program and for "machine-like" design SolidWorks is superior to Blender.

General subD modelling guidelines

When modelling with polygons - the trick is to first focus on the large picture/lines and not worry about details

Most used shortcuts (what is needed for INF4500)

In blender we have to modes: Object mode (top level / assembly of parts) / edit mode (drawing inside a part)

We first add a new part in "object mode", then start modifying the part in "edit mode"

In edit (drawing) mode:
