In the second lesson:
We have examined the properties of Solid, Parametric,
Feature based SolidWorks CAD system
We have constructed and modified some simple models
Now we’ll continue with part creation.
2
Library of features
As you already know, the first feature always requires a sketch created on one of the reference planes.
That sketch may then subjected to different operations in order to create the desired feature.
3
Sample features
Extrusion
Sweep
Hole
Revolution
Loft
Extruded cut
4
We’ll build these two parts
block01.SLDPRT
block02.SLDPRT
We’ll build these two blocks. Later we’ll used them to assemble Lego-like structures.
5
Open a new part

6
Create a 2D sketch
Building the first feature begins with a 2D sketch on one of the reference planes that come with a new part.
7
Create a 2D sketch
3
2
1
Select Front Plane (either from Feature Manager window or Model view widow) and open Sketch on
this plane
8
Create a 2D sketch
1
Select Centre Rectangle from sketching tools. Sketch the rectangle locking the centre to the origin of
the sketch coordinate system
9
Fully define the 2D sketch
Undefined sketch - blue
Fully defined sketch - black
Add dimensions to define the sketch
10
Extrude 2D sketch into 3D feature
From Features menu select Extrude and define the length of extrusion as 10mm
11
Shell-out the extrusion
2
1
Select the face 1 and select Shell from Features menu. Specify shell thickness 2mm
12
Define material and save the part
The part has two features: Extrusion and Shell. Define material properties (1060
Alloy) as save as block01.SLDPRT
13
Modify block01 to create block02
block01.SLDPRT
block02.SLDPRT
Change the length 30mm into 15 mm.
14
Modify block01 to create block02
Change color to blue and save part as block02.SLDPRT
15
Examine different ways to
display model
Shaded with edges
Shaded
Hidden lines
removed
Hidden lines
visible
Wireframe
Open Display style menu and examine different ways of showing the model.

Summary
In this lesson we have:
Created two different parts taking advantage of parametric
formulation of SolidWorks
Learned different ways to display the model
In the next lesson we’ll use these parts to create as
assembly
