Units = MMGS
We will focus on the boundary first, and then worry about the circular sketch pattern on the interior. I

Revolve Example Thumbtack
1. Create the following sketch on the front plane.
2. The revolve works differently depending on if we close the sketch or not. In the above
figure, the sketch is open (as you need a solid line, not a construction line to close t
Alphabet of Lines
- lines in drawings that represent visible edges and contours of an object
- shown as THICK lines (0.5 0.6 mm)
- short, narrow dashed lines
- represent the hidden features of an element
Practice Final Problem 2
Initially, this figure looks very complicated. Fortunately, we can make it with one sketch and do a lot of different
extrusions and cuts. We will also familiarize ourselves with how to make a SECTION VIEW with multiple lines.

Sketching on a Plane Inside The Body
Units = mm
1. Create the following familiar sketch on the FRONT PLANE (MAKE SURE IT IS FULLY DEFINED):
2. Do a MID-PLANE extrusion of 20 mm (This is equivalent to extruding 10 mm in Direction 1 and 10 mm in
Practice Final Problem 1
We first want to make the front face of the figure. We do so by creating the fully defined figure
with the sharp corners shown in the first figure.
Next we round the one corner by using the FILLET tool:
We then extrude this

To add the auxiliary view (VIEW A), go to the VIEW LAYOUT toolbar and press AUXILIARY VIEW.
Next, click on the edge you want to make
In SolidWorks, constraints define how each part of the sketch interacts with each other.
For example, constraints are used to make two lines perpendicular, or to make an arc
tangent to some other surface.
Constraining an Individual Line
Mirrored Constraints, Page 1
We will create the object shown above by sketching half of the object and mirroring it, as we have done before.
This document concerns the procedure for fully defining an object before mirroring by making u
Partial Auxiliary Views
We are making the same drawing file as last weeks example, except we are cropping the auxiliary view so that we
see only the auxiliary feature, and none of the other parts.

Creating Drawing Files
When you finish creating your part, click File > Make Drawing From Part.
If you have not yet saved the file, SolidWorks will prompt you to do so now.
SolidWorks will ask you to choose your paper size. I will tell you what size
2-D sketches are brought into 3-D most simply by an extrusion.
What an extrusion does is take a 2-D sketch and bring out uniformly into a third dimension.
Before extruding a sketch, you must first make sure that your sketch i
Drawing File Conventions
There are two different standard ways to project a normal 3-D image in two dimensions
The standard in the United States is to use third angle projection
This is analogous to making a glass box around your object, projecting each
Splines & Sweeps
Figure 1 (Different views of the same part)
To create a swept part both a "path" and "profile" are required (at minimum). In this case we
will also be using a few guide curves to change the final profile of the part.

Aligned Section View
Create the sketch from the top view on the top plane. In this approach, we do all of the sketching on one sketch, and extrude the different areas,
We sketched everything on one sketch, so we dont need to sketch anymore
It is important in SolidWorks to make sure you are using the correct unit system.
Unit system can be changed by clicking TOOLS, OPTIONS. A menu will appear, and
click on the tab labeled DOCUMENT PROPERTIES. Click UNIT
