If you click the Model name-tab, after completing Tutorials 1 and 2, you will not see Solids. Tutorials 1 and 2 add kinematic elements only: Parts and Joints. Part and Joint elements are symbolic only, and for kinematic analysis, and are not Solids.
We can add Solids elements to Parts in two ways:
•Add a Profile/Extrusion element to a sketch-loop
•Import SOLIDWORKS Part and Assembly documents, or STL file-types from other 3D CAD.
1.Repeat Tutorial 1, to become more confident with the tools you need to use to add a rotating-Part.
2.Add a sketch-loop to a Part with basic sketch-elements
What is the Part-Outline?
•The Part-Outline is the symbolic shape around each Part: it is an oval shape around each Part we add to the model, or a rectangular shape around the Base-Part.
What is a sketch-loop?
•A sketch-loop is a series of sketch-elements- that we join end-to-end.
•There is one Point where we join the sketch-elements, we merge the two Points into one Point.
•If there are two coincident Points, it is not defined as a sketch-loop.
