UNIT 1 INTRODUCTION TO MODELING & SOLIDWORKS SOFTWARE

1.1 INTRODUCTION This Module discusses terminology and SolidWorks software

characteristics, design intent, open & exit program, Software interface,

toolbar, mouse button and customize option.

1.2 LEARNINGS OUTCOMES

Upon successful completion of this lesson, you will be able to:

Describe the key characteristics of a feature-based, parametric solid modeler.

Distinguish between sketched and applied features. Identify the principal components of the SolidWorks user interface. Explain how different dimensioning methodologies convey diferent

design intents.

1.3 LEARNING CONTENTS 1.3.1 What is SolidWorks?

SolidWorks is design automation software. In SolidWorks, you sketch ideas and experiment with different designs

to create 3D models.

SolidWorks is used by students, designers, engineers, and other professionals to produce simple and complex parts, assemblies, and

drawings.



1 - 2

1.3.2 Terminology and SolidWorks Software Characteristics

1.3.2.1 Featured-based Made up of a number of individual piece part

Figure 1.1: Concept of featured based modeling



1 - 3

Applied



1 - 4

Can be classified as either sketched or applied 9 Sketched Feature:

Is based upon a 2D sketch. Generally that sketch is

transformed into a solid by extrusion, rotation, sweeping or

lofting.

9 Applied Feature:

Created directly on the solid model. Fillets and chamfers are

examples of this type of feature.

Applied

Figure 1.2: Different plane on featured based.

Figure 1.3: Multiple feature sketch on many plane.



1 - 5

1.3.2.2 Parametric solid modeling Enable you to quickly and easily make changes to the model

1.3.2.3 Fully associative

Model is fully associative to the drawings and assemblies that reference it.

Any model changes will reflect the associated drawings and assembly.

Figure 1.4: File references

1.3.3 Design Intent Is your plan as to how the model should behave when it is changed. For example: if you model a boss with a blind hole in it, the hole should

move when the boss is moved.

Several factors contribute to how you capture design intent: o Automatic relations o Equations o Added relations o Dimensioning



1 - 6

1.3.3.1 Some examples of different design intent in a sketch

1.3.3.2 How feature affect Design Intent

The choice of features and the modeling methodology are also

important. For example, consider the case of a simple stepped

shaft as shown below. There are several ways a part like this could

be built.

o The Layer Cake Approach o The Manufacturing Approach o The Potters Wheel Approach

Dimensioned like this will keep the holes

positioned relative to the left edge of the plate.

The positions of the holes are not affected by

changes in the overall width of the plate.

Dimensioning from the edge and center to

center will maintain the distance between the

hole centers and allow it to be changed that

way.

Dimensioned like this will keep the holes 20

mm from each end regardless of how the

overall plate width is changed.

((aa))

((bb))

((cc))



1 - 7

The Layer Cake Approach

Builds the part one pieces at a time, adding each layer, or feature,

onto the previous one.

The Manufacturing Approach Modeling mimics the way the part would be manufactured. For

example, if this stepped shaft was turned on a lathe, you would

start with a piece of bar stock and remove material using a series of

cuts.

The Potters Wheel Approach Builds the part as a single, revolved feature.

1.3.4 Open & Exit Program

Running Programs

The quickest way to start a program is to double-click on a desktop shortcut.

Some programs may not have desktop shortcuts. The Programs menu lists the entire application programs resident on

the computer.



1 - 8

Exit a Program

Select or click File, Exit to end a program. If the file has unsaved changes, you have the chance to save them

before exiting.

1.3.5 Open & Save File

Opening a File

The quickest way to open a file is to double-click on it. The File menu displays your most recently used files.



1 - 9

Saving and Copying Files

Saving a file preserves the changes that you have made to it. Use File, Save As to copy a file. File, Save As creates an exact duplicate of the file as it existed at the

moment that you copied it.

1.3.6 Parts, Assemblies & Drawings

The SolidWorks model is made up of: o Parts Assemblies Drawings

Parts are single three-dimensional (3D) objects. Parts are the basic building blocks of 3D modeling. Parts can be included as components

in assemblies and represented in drawings.

Assemblies are logical collections of components. These components can be parts or other assemblies. An assembly within an assembly is

called a subassembly.

Drawings are 2D representations of 3D parts or assemblies. Drawings are needed for manufacturing, quality assurance, supply chain

management, and other functions.

Parts, assemblies, and drawings are associative. This means that changes in one place are reflected in all of the places that they need to

be reflected. Changes that you make to an assembly are reflected in

the drawings of that assembly. Changes that you make to a part are

reflected in the assembly.

Display most recently used files



1 - 10

Typically, you design each part, combine the parts into assemblies, and generate drawings in order to manufacture the parts and

assemblies.

The following illustration shows the relationship among parts, assemblies, and drawings.

Figure 1.5: Relationship among parts, assemblies, and drawings

1.3.7 Software Interface

The first thing you may notice about the user interface is that it looks like

Windows. That is because it is Windows! The interface is how you interact

with the computer in the following ways:



1 - 11

Use windows to view files. Use the mouse to select buttons, menus, and model elements. Run programs like SolidWorks mechanical design software. Find, open, and work with files. Create, save, and copy files. Menu provides access to many of the commands hat the SolidWorks

UNIT 2 SKETCHING

2.1 INTRODUCTION

This Module introduces 2D Sketching, the basic of modeling in

SolidWorks. It discusses the Planes, sketch entities and geometry (Line,

Box, Circle, Centerpoint Arc, Tangent Arc, Three point Arc, Ellipse, Spline,

Point, Fillet and Center lines), Sketch status, Sketch relations,

Dimensioning, Fillet, Offset, Trim, Convert and Mirror.



Insert a new sketch. Add sketch geometry. Establish sketch relation between pieces of geometry. Understand the state of the sketch. Use sketch tools to add fillets. Extrude the sketch into a solid.

2.3 LEARNING CONTENTS 2.3.1 Why needs sketches?

Solid models are built from features. Shape features have sketches. Sketched features are built from 2D profiles. Illustration below shows how a given sketch can form the basis of

several different types of features.

Unit 2 Sketching

2.3.2 Planes Since sketches are flat, or planar, it needs a plane on which to sketch.

A SolidWorks part contains three default sketch planes. Default planes

- Front, Top, and Right

Figure 2.1: Three default references planes intersect at the origin

Correspond to the standard principle drawing views: o Front = Front or Back view o Top = Top or Bottom view o Right = Right or Left view

2.3.3 Sketch Entities and Geometry SolidWorks offers a rich variety of sketch tool for creating profile geometry.

Figure below shows most of sketch toolbars that can be found in the

sketch entities.

Unit 2 Sketching


2 - 5

2.3.4 Sketch Complexity In many cases, you can produce the same result by creating an extruded

feature with a complex profile, or an extruded feature with a simpler profile

and some additional features.

For example, if the edges of an extrusion need to be rounded, you can draw a complex sketch that contains sketch fillets (A), or draw a simple sketch and add the fillets as separate features later (B).

A) Complex sketch Extrude

B) Simple sketch Add fillet feature

Consider your design intent: o Complex sketches rebuild faster. Sketch fillets can be

recalculated much faster than fillet features, but complex sketches

can be harder to create and edit.

o Simple sketches are more flexible and easier to manage. Individual features can be reordered and suppressed, if necessary.

Unit 2 Sketching

2.3.5 Mechanics of Sketching

To sketch geometry, there are two techniques can be used: Click-Click

Select line. Position the cursor where you want the line to start. Click

(press and release) the left mouse button. Move the cursor to where

you want the line to end. A preview of the sketch entity will follow the

cursor like a rubber band. Click the left mouse button a second time.

Click and Drag

Select line. Position the cursor where you want the line to start. Press

and hold the left mouse button. Drag the cursor to where you want the

sketch entity to end. A preview of the sketch entity will follow the cursor

like a rubber band. Release the left mouse button.

2.3.6 Beginning a Sketch (Draw Rectangle)

i) Select any plane at Feature Manager Design Tree to draw sketch.

ii) Click Sketch on the Sketch Command Manager.

iii) Click Rectangle on the Sketch Tools toolbar.

iv) Move the pointer to the origin and click the left mouse button.

2.3.7 Rules That Govern Sketches

Different types of sketches will yield different results. Several different

types are summarized in the table below. It is important to note that some

of the techniques shown in the table below are advanced techniques that

are not covered here and need more experience user.

Sketch Type Description Special Considerations

A typical standard sketch that is a neatly closed contour.

None required.

Multiple nested contours create a boss with an internal cut.

None required.

Open contour creates a thin feature with constant thickness.

None required.

Corners are not neatly closed.

Rebuilt Error. Unable to create feature due to geometry condition.

Sketch contains a self intersecting contour.

Use the Contour Select Tool. If both contour are selected, this type of sketch will create a Multibody Solid.

Although this will work, multibodies are an advanced modeling technique that you should not use until you have more experience.

This sketch of the first feature contains disjoint contours.

This type of sketch will create a Multibody Solid.

Although this will work, multibodies are an advanced modeling technique that you should not use until you have more experience.

Unit 2 Sketching


2 - 8

2.3.8 The Status of a Sketch

Under defined o There is inadequate definition of the

sketch.

o You can drag endpoints, lines, or curves until the sketch entity changes

shape.

o Additional dimensions or relations are required. o Under defined sketch entities are blue (by default).

Fully defined o The sketch has complete

information.

o No additional dimensions or relationships are required.

o Fully defined sketch entities are black (by default).

Over defined o Contains duplicate

dimensions or conflicting

relations and it should not be

used until repaired.

o Over defined sketch entities are red (by default).

Unit 2 Sketching


2 - 9

2.3.9 Making a Fully Define Sketch

Design intent in a sketch is captured and controlled by a combination of two things:

o Sketch Relation Create geometric relationships such as parallel, collinear,

perpendicular, or coincident between sketch elements.

o Dimensions Dimension are used to define the size and location of the sketch

geometry. Linear, radial, diameter and angular dimensions can be

added.

To fully define a sketch and capture the desired design intent requires understanding and applying a combination of relations and dimension.

2.3.9.1 Sketch Relation

Unit 2 Sketching


2 - 10

Unit 2 Sketching


2 - 11

Concentric between two or more arcs or circle.

Coradial between two or more arcs or circle.

Tangen between line with arc/circle or between arc/circle with arc/circle.

Unit 2 Sketching


2 - 12

2.3.9.2 Add Relations

Appears when you click Add Relation on the Dimensions/Relations toolbar.

Appears when you select multiple sketch entities in the graphics area.

Or, right-click the entity or entities, and select Add Relation from the short-cut menu.

Or, click Tools, Relations, Add

2.3.9.3 Dimension

It is used to define the size. In SolidWorks, dimensions are not just static numbers that tell

you the size of something. Instead, the dimensions are used to

change the size and shape of the model.

The type of dimension is determined by the items on which you click. For example, if you pick an arc the system creates a

radial dimension. If you pick a circle, you get a diameter

dimension, while selecting two parallel lines creates a linear

dimension between them.

2.3.9.4 Dimensioning a Sketch

i) You dimension 2D or 3D sketch entities with the Smart

Dimension tool. ii) You can drag or delete a dimension while the Smart

Dimension tool is active. iii) Click Smart Dimension on the Dimensions/Relations

toolbar, or click Tools, Dimensions, Smart. The default

dimension type is Parallel.

iv) Select the items to dimension, as shown in the table 1.

v) As you move the pointer, the dimension snaps to the

closest orientation.

vi) Click to place the dimension.

Unit 2 Sketching


2 - 13

Table 1: Item to be Dimensioning

To dimension the... Click... Note:

Length of a line or edge

The line.

Angle between two lines Two lines, or a line and a model edge.

Placement of the dimension affects the way the angle is measured.

Distance between two lines

Two parallel lines or a line and a parallel model edge.

Perpendicular distance from a point to a line

The point and the line or model edge.

Distance between two points

3.3.7 Revolve Feature

A Revolve feature is created by rotating a 2D profile sketch around an axis of revolution.

The profile sketch can use a sketch line or a centerline as the axis of revolution.

The profile sketch cannot cross the axis of revolution.

To Create a Revolve Feature: 1. Select a sketch plane.

2. Sketch a 2D profile.

3. (Optional) Sketch a centerline.

9 The axis of revolution must be in the sketch with the profile. It cannot be in a separate sketch.

3 - 11 3 - 11

3.3.8 Sweep Feature

The Sweep feature is created by moving a 2D profile along a path. A Sweep feature is used to create the handle on the candlestick. The Sweep feature requires two sketches:

o Sweep Path o Sweep Profile

Sweep Overview Rules The sweep path is a set of sketched curves contained in a sketch, a

curve, or a set of model edges.

The sweep profile must be a closed contour. The start point of the path must lie on the plane of the sweep section. The section, path or the resulting solid cannot be self-intersecting.

3.3.9 Loft Feature

Blends multiple profiles together. A Loft feature can be a base, boss, or cut.



3 - 12 3 - 12

To Create a Simple Loft Feature: 1. Create the planes required for the profile sketches. Each sketch should

be on a different plane.

2. Sketch a profile on the first plane.

3. Sketch the remaining profiles on their corresponding planes.

4. Click Loft on the Features toolbar.

5. Select each profile.

6. Examine the preview curve and the connectors.

7. Click OK .



3 - 13 3 - 13

3.3.10 Fillet Feature

Fillet/Round creates a rounded internal or external face on the part. You

can fillet all edges of a face, selected sets of faces, selected edges, or

edge loops.

Types of fillets:

Recommendations for Fillets: In general, it is best to follow these rules when making fillets:

Add larger fillets before smaller ones. When several fillets converge at a vertex, create the larger fillets first.

Add drafts before fillets. If you are creating a molded or cast part with many filleted edges and drafted surfaces, in most cases you should

add the draft features before the fillets.

Save cosmetic fillets for last. Try to add cosmetic fillets after most other geometry is in place. If you add them earlier, it takes longer to rebuild

the part.



3 - 14 3 - 14

To enable a part to rebuild more rapidly, use a single Fillet operation to treat several edges that require equal radius fillets. However, if you

change the radius of that fillet, all the fillets created in the same

operation change.

To create fillets:

1. Click Fillet on the Features toolbar, or click Insert, Features, Fillet/Round.

2. Set the PropertyManager options. For constant radius fillets only,

you can use the FilletXpert to add or modify fillets.

3. Click OK

3.3.11 Chamfer Feature

Creates a beveled feature on selected edges, faces, or a vertex.

Offset Distance . Create a plane parallel to a plane or face, offset by a specified distance. This is the default plane created.

Normal to Curve . Create a plane through a point and perpendicular to an edge or curve.

If the selected line is in the same plane as the selected plane, the new plane rotates around the selected line.

If the selected line is parallel to the selected plane, the new plane moves to the parallel line and rotates around the line.

In this example, you select just the helix to create the new plane. Plane 4 is perpendicular to the end of the tapered helix.

A circle is swept along the helix to create a spring.

3.3.17 Families of Parts

Many times parts come in a variety of sizes. This is called a family of parts. It is not efficient to build each version individually. Design Tables simplify making families of parts.



3 - 25 3 - 25

What is a Configuration? A configuration is a way to create a family of similar parts within one

file.

Each configuration represents one version of the part.

Suppress / Unsuppress (also known as revolved) Feature Suppress is used to temporarily remove a feature. When a feature is

suppressed, the system treats it as if it doesnt exist. That means other

features that are dependent on it will be suppressed also. In addition,

suppressed features are removed from memory, freeing up system

resources. Suppressed features can be unsuppressed at any time.

To create a configuration manually:

1. In either a part or assembly document, click the

ConfigurationManager tab at the top of the FeatureManager

design tree to change to the ConfigurationManager.

2. In the ConfigurationManager, right-click the part or assembly name

and select Add Configuration. 3. In the Add Configuration PropertyManager, type a Configuration

Name and specify properties for the new configuration. You can specify a configuration specific color.

4. Click .

5. Click the FeatureManager design tree tab to return to the

FeatureManager design tree.

6. Modify the model as needed to create the design variation.

7. Save the model.

To activate a different configuration:

1. Click the ConfigurationManager tab to change to the

ConfigurationManager.

2. Right-click the name of the configuration you want to view and select

Show Configuration or Double-click the configuration name. The named configuration becomes the active configuration, and the

view of the model updates to reflect the newly selected configuration.

Unit 4 - Part Assembly


4 - 1

UNIT 4 PART ASSEMBLY

4.1 INTRODUCTION Part files, as you have learned, typically contain one contiguous solid

modeling. Assembly files can contain more than one part. Assembly files

give you the capability of assembling the parts you have created, putting

the parts together as if you

were actually building the

assembly in real life. The

following figure shows an

example of an assembly. It

is the example you will use

to learn about assemblies

in this lesson.

4.2 LEARNING OUTCOMES Upon successful completion of this module, you would be able to:

create a new assembly insert components into an assembly using all available techniques. add mating relationships between components. utilize the assembly-specific aspects of the FeatureManager design

tree to manipulate and manage the assembly.

insert sub-assemblies. use part configurations in an assembly.



4 - 2

4.3 LEARNING CONTENTS

4.3.1 Introduction to Part Assembly

You can build complex assemblies consisting of many components, which

can be parts or other assemblies, called sub-assemblies. For most

operations, the behavior of components is the same for both types. Adding

a component to an assembly creates a link between the assembly and the

component. When SolidWorks opens the assembly, it finds the component

file to show it in the assembly. Changes in the component are

automatically reflected in the assembly.

The document name extension for assemblies is .sldasm

1] Open an existing part

Open the part Main body. A new assembly will be

created by using this part.

The first component added to an assembly should be

a part that will not move (fix). By fixing the first

component, others can be mated to it without any

danger of it moving.
