Overcoming Default Settings by use of Templates:
Don’t you just hate that:
 sometimes when you open a file to make a new part you have to
remember to set the default units if not working with mm.
 the default titlebox template using ISO instead of ANSI format.
 that angle of projection might be 1st instead of 3rd angle of projection.
 you have to go type your own personal information into the title block
every time you create a new drawing.
 that the principle planes don't automatically show up in the work
space.
 every night at 11:00 SolidWorks takes control of your computer and
starts a defragmenting process.
Wouldn’t it be nice you could save an empty file with the default settings the
way you wanted?.....Well, you can! …It's possible to save a file which holds
the presets you want which is empty of models. These types of files are
called Templates.
Templates:
Templates are documents (part, drawing, and assembly documents) that
include user-defined parameters and are the basis for new documents.
You can maintain many different document templates. For example, you can
create:
- A Part template using millimeters and another template using inches
- A Part template using ANSI or another template using ISO standards
- A Drawing template with 3rd angle projection the default mode.
You can organize your document templates by placing them on different
tabs in the New Solid Works Document dialog box.
Templates can include settings for such document properties as:
- grid spacing
- extension line and break line gap
- dimension offset distance and break dimension gap
- note bent leader length
- balloon bent leader length
- arrow size and section view arrow size
- text scale and text display size
- material density
Template Creation:
To create a template:
1. Click New
(Standard toolbar) or File, New.
2. In the dialog box, double-click the appropriate icon for the type of
template that you want to create: Part, Assembly, or Drawing.
3. Click Options
(Standard toolbar) or Tools, Options.
4. On the Document Properties tab, select options to customize your
new document template, then click OK.
Only options on the Document Properties tab are saved in a
document template.
5. Click File, Save As.
6. Select an appropriate template type for Save as type:



Part Templates (*.prtdot)
Assembly Templates (*.asmdot)
Drawing Templates (*.drwdot)
7. Type a name for File name. The extension is added automatically.
The template file will automatically save in the template folder
located at C:\Program Files\SolidWorks\data\templates
Create the following three templates:
Template 1) This will be a template used when creating Parts to be made
using metric dimensions in millimeters.
Open a part file starting from the standard Part template and make the following
changes:
1) Turn on the visibility of the Front, Top, and Side planes.
Right click each plane in the feature manager and click Show.
2) Select the base units as millimeters
Options…Document Properties tab and Unit
√ MMGS
3) Turn on visibility of Cosmetic Threads
Options…Documents Properties tab and Detailing…Annotations Display
√ Cosmetic Threads √ Shaded Cosmetic Threads
4) Set the Dimension style to ANSI.
Options…Document Properties tab and Drafting Standard:
Dimensioning Standard: ANSI
Save this as your 1st template named:
Part_MM.prtdot:
Template 2) This will be a template used when creating Parts to be made using metric
dimensions in inches. Open of the Part_MM just created and make the additional
modification:
Select the base units as inches with 3 decimal places showing
Options…Document Properties tab and Unit
√ IPS
and
set
Length .123
Save this as a your 2nd template named:
Part_IPS.prtdot:
Template 3) Finally create a Drawing template which has the angle of projection set as
3rd angle and has your name already typed into the titlebox.
Open a new Drawing file and make the following changes:
1) Select Options and Document Properties to set format to ANSI (instead of ISO).
2) Select B Landscape title block.
3) Right click the mouse, select Properties and set the projection to 3rd angle.
4) Right click the mouse, select Edit Sheet Format and add a note with
Your Name
Class number: EGR 105
Also correctly size any incorrectly sized labels.
Save this 3rd template as a drawing template
Draw_3rdAngle.dwgdot
The next time you start up SolidWorks these templates will be available using the
Advanced Option during the New Solid Works Document selection.
You may are also able to
define which template
is your default template
under the Options
…System Options
…Default Template detail.
Adding access to Toolbox Parts
SolidWorks has a library of existing parts that you can access
through a tool called SolidWorks Toolbox. For instance if you
want to use a wide variety of parts such as bolts, washers, screws,
bearings or other standardized parts, you don't actually have to
create a new part. Just find the correct part in the toolbox and use
it.
However, this toolbox of parts needs to be loaded for you to use it.
To load SolidWorks Toolbox use the following steps:
1) Select from the main menu: Tools…Add-ins
2) Check the tools: √ SolidWorks Toolbox
and
√ SolidWorks Toolbox Browser
3) Whenever working with a part, the toolbox will now be
available through the Design Library.
Rules for Multiview Drawings: A Dramatic Reading
1) Every point or feature in one view must be aligned on a
parallel projector in any adjacent view
2) Distances between any two points of a feature in related
views must be equal.
3) Features are true length or true size when the lines of sight
are perpendicular to the feature.
4) Features are foreshortened when the lines of sight are not
perpendicular to the feature.
5) Areas that are the same feature will always be similar in
configuration from one view to the next, unless viewed as an
edge.
6) Parallel features will always appear parallel in all views.
7) Surfaces that are parallel to lines of sight will appear as
lines or edge views.
8) No two contiguous areas can lie in the same plane.
Additional Corollaries:
9) A normal plane appears as a true size-true shape in 1 view
and an edge view in 2 views
10) An inclined plane appears as a foreshortened shape in 2
views and a line in 1 view.
11) An oblique plane appears as a foreshortened shape in all 3
views.

Visualization:
--The ability to think in three dimensions.
--To be able to study the views of an object and form a mental
picture of the object.
When working from the three views it is not unusual to have
difficulty trying to form a mental picture of the object in your
head. Study the views and determine if there is one dominant
shape of the object. Try and construct a box which contains the
dominant shape.
From the basic shape, attempt to add other features by removing or
adding material. If this fails, there are more systematic methods
used to locate individual points which can be used to reconstruct
the box which are discussed in most graphic communication texts.

Locate the thread notes in the dimensioned pictorial below.
Notes: Can you notice what features of the holes are missing from
the dimensions or hole notes?
-- The depth of the 0.50 diameter counter-bored hole is missing on
the handout. We will assign it a depth of 0.25
-- The large 0.75 diameter hole is missing its location with respect
to the width. It should be shown as centered across the
width of the base
Demo 5.1
Advanced Holes and the Inspect Function.
How are the Notes added?
Hole notes are added in Drawing files by use of
two common tools:
Smart Dimension
and
Hole Callout
Inspecting and Measuring features in Solid Works:
Because all the information on the part is stored as parametric values, it’s very easy for
Solid Works to generate geometric data about the features. Solid Works provides a tool
with which you can measure line length, surface area and surface perimeter.
Locate this Measure tool under the Tools pull down menu or on the Evaluate tool tab.
Examples: Load this file (Lecture5_Demo) from the file sent to you by email
Use it to
-- measure the length of a line
-- measure the circumference of a circle
-- measure the area and perimeter of a flat surface
-- measure the area and perimeter of a curved surface
Week 5 Class Work
Read the following notes before starting on CW 5.1
In CW5.1 the depth of the 0.50 in diameter counter-bored hole is missing on the
handout; use a depth of 0.25 in. The large 0.75 in diameter hole is centered across the
width of the base.
You can use the Fillet command to easily create the 0.25 in radius on the bottom of the
block. When you select a line to be filleted, click on the line that will disappear once the
fillet is in place.
Class Work 5.1 – Using Solid Works, create a solid model part and a drawing of the
three principal views of the Base shown in the attached Handout CW 5. Note that you
are making a model of the part labeled with the number 2 and the name BASE. The
front view should be the front-left of the isometric shown in the handout (this shows the
three holes most clearly.) Use a B-size title block and remember to add centerlines to the
drawing. Measure the Area and Perimeter of the surface identified in the figure below
and add this information as a note in the upper left corner of the drawing. Submit only the
drawing file.
Class Work 5.2 – Using Solid Works, create a solid model and a drawing of the three
principal views of the U-Clamp shown in the attached Handout CW 5. The front view
should be the front-right of the isometric shown in the handout. Add a completed B-size
title block and remember to add centerlines to the drawing. Submit only the drawing file.
Surface of
interest
Class Work 5.3 – Using Solid Works, create a solid model and a drawing of two
principal views of the Fastener shown in the attached Handout CW 5. The front view
should show the 0.13 diameter hole in its circular view and the other view should show
the end view of the fastener. Add a completed B-size title block and remember to add
centerlines to the drawing. Submit only the drawing file.

Home Work 5:
The homework this week is to continue working through the tutorials in your
Beginners Guide to Solid Works 2013.
HW 5.1 Using Figure HW 5.1 (shown below), create a virtual model of the
object as SolidWorks Part using a scale where one multi-view block represents
10 mm. Once the Part file is created, then make a Drawing of the model which
shows the front, top, right side, and an isometric view of the object. This should
be placed on a B-size title block. Be sure to fill in the title block information
which should include the HW number, your class, and your name. Submit only
the printout of the Drawing file, not the Part file.
HW 5.2 From Reyes “Beginner’s Guide to SolidWorks 2013” complete the
Top Cover tutorial which starts on page 99. Make sure you set the Units to
“inches” before starting construction of the model. Create a drawing of an
isometric view in a B-size title block to hand in. Submit only the print out of
the drawing file.
HW 5.3: From Reyes "Beginner's Guide to SolidWorks 2013 complete the
Offset Shaft tutorial starting on page 125. Also complete a drawing of the part
showing a profile, an end, and an isometric view of the shaft on a B-size title
block. Remember to add hidden and center lines where appropriate. Submit
only a print out of the drawing file.

Lecture 05 Addendum: Adding External Cosmetic Threads:
Cosmetic threads are automatically added to threaded holes made with the Hole
Wizard command. However, if you wish to add interior threads to a hole made
using the Extruded Cut or add exterior threads to a cylinder, you need to use a
different technique to add the threads.
Step 1: Select the circular edge at one end of the surface you wish to add the
threads to.
Pick
Edge
Step 2: Activate the cosmetic
thread tool found under the menu at
Insert…Annotation…Cosmetic Thread
Step 3: Specify the length of the
thread and the diameter
its based on. When complete,
click the Green Checkmark
The thread should now be displayed.
