−Sheet format

−BOM

−Revision Block

• Tools Options

• Property Tab Builder (Newer Feature Still working on Templates)

Default with SolidWorks

• By default when SW opens - NOVICE is set

• The template that opens is what the default is set to, if no default is set then it defaults to the “Templates” that were created upon install.

• Should already be set. If not just click on the icon shown.

Default with SolidWorks• TEMPLATES: This is set when you open SolidWorks the first time, there are a few generic

selections as a standard. The Custom Templates have already been created and can be found in the following location:

• L:\VAULT\DPT Templates

• Click on the Advanced button in the lower Left corner if it has not already been selected.

• If it has been selected you should see what is in the image on the right (below).

Pre-Template set up work Metadata - Sometimes referred to as custom properties or attributes, these are typically the attributes used to

identify information in documents.

−Part Number - Customer ID

−Description - Weight

−Material - Program

−Finish - Material Size

−Drawn By / Date - Surface Treatment

−Check By / Date - Reference Drawing

−Approved By / Date - Blank Number

−ANY INFORMATION THAT WILL BE USED IN BOM, DRAWINGS ETC…

Define location for all templates to be saved

− PDM System? We will be migrating into a PDM System in the near future. Hopes are that most of the required information for the PDM System will already be in the Parts/Drawings

−Network Shared Location: L:\VAULT

−Who is the Admin?

−At present I am the Admin. However, I will be teaching everyone how to use the Admin tools and the system as a cross over function.

Dauphin Precision ToolSolidworks Design Considerations

Creating SolidWorks Parts

START WITH A PLAN:

Prepare a strategy that establishes desirable characteristics of good models

Build intelligence into your part that is mindful of dimensioning schemes and manufacturing processes

Think as far forward as possible. Don’t be afraid to experiment and change course when you encounter obstacles

Functionality Predictability

Performance Stability

Accuracy Changeability

With the origin placed at a meaningful

location you may be able to use the

default planes for assembly mating.

This allows you to edit or suppress part

features without affecting the assembly.

Thoughtful placement of the origin allows

you to make the most of symmetry.

It is very useful to control the orientation and the position of the part using the origin.

As you create the part consider if there is a logical orientation of the geometry that

will help you organize and control the design? Does the orientation of the part

accurately communicate the design intent? Can six standard views be created in

their correct orientation?

Locating the origin at a meaningful location will allow you to dimension additional

features off the default planes. Convenient placement of the origin also allows you to

take advantage of symmetry.

MAKE USE OF THE ORIGIN

Building parts symmetrically about the origin can significantly reduce modeling time.

Mirroring features is typically easier than mirroring sketch entities.

Mirroring bodies is quicker and more reliable than mirroring features.

By creating geometry symmetrically around the origin can significantly reduce modeling time, more importantly it is easier to modify the part later. Mirroring bodies is faster than mirroring features, dynamic mirroring is a useful tool when sketching. You can also accomplish symmetry by using Circular patterns.

CONSIDER SYMMETRY

DEFINE WHAT IS IMPORTANT

Think through your design intent and use the appropriate relationships to ensure that functionality is upheld.

This will communicate your strategy to others while making changes easier to apply.

As you constrain geometry consider how the part is used and think how to define the features that are important. If engineering drawings require a different dimensioning scheme you can add them as reference.

CREATE FEATURES IN LOGICAL SEQUENCE

Top down – start with the smallest mass that will contain the entire part then subtract material

Bottom up – begin with a core shape then create additional features

Fillets can be sketched or applied features – though there are limitations to sketch fillets

Sketch Based Features

Applied Features

Applied Features should appear towards the

Bottom of the Feature Manager

Apply Drafts before Fillets

Apply Fillets before Shells

LIMIT THE SCOPE OF FEATURES

Separate features allow you to simplify part representation by suppressing any combination of features

Several simple sketches are easier to manage than one complex sketch

When you’re creating a model it is good practice to break the part down into separate features. Sometimes we try to combine too many details into one feature, producing an “all or nothing” scenario. Separate features permit you to edit, suppress, or delete any combination of features. This ability allows you to simplify the part representation; useful for speeding up assemblies or simulations.

GUIDE LINES FOR SKETCHES

For most cases use fully defined sketches

Generally it is good practice to use fully defined sketches and to keep your sketches simple.

Keep sketches simple due to the fact that complex sketches are more difficult to understand or modify.

Use construction geometry to get the desired dimensioning scheme. Sometimes it will be necessary to create centerlines or construction geometry to get the dimensions that can be ‘Marked for Drawing’.

Be sure to understand sketch relationships

To ensure stability and predictability it is very important for you to understand the graphical feedback and the relationships you are creating in sketches. It is useful to rotate the part to be sure you are selecting the correct entities; also you can sketch without automatically inferring references by pressing down the Ctrl key.

CAREFULLY CHOOSE REFERENCES

Choose references that allow the geometry to move with intent as changes are made

Create only enough references that allow the model to follow design intent

Select references that won’t disappear by relating to sketches rather than edges

As often as possible reference default datum planes

DON’T ADD FEATURES WHEN YOU CAN EDIT

Rollback and insert features – or edit existing features. Especially important on parts with complex geometry or a large feature count.

Insert features close to the parent geometry.

This practice keeps features in a logical sequence and reduce rebuild time while working.

One of the advantages of a feature based CAD system is that you can return to any point in the history of the geometry creation and make edits.

It is important to get comfortable rolling back your model.

SURFACES AS CONSTRUCTION GEOMETRY

CAD users tend to think surfacing makes models more complicated when in fact, the opposite can be true. This technique of mixing surfaces with solid features is known as hybrid modeling.

PRINCIPLES OF PARAMETRIC MODELING

• When confronted with a design problem, engineers are faced with a methodological choice: analytical study or CAD and simulation

• The power and speed of designing in SolidWorks® has led many to invest their time (sometimes exclusively) in CAD and simulation

• Skipping the analytical methods can result in a loss of fundamental design insight and suboptimal parameterization

• The intent of parametric modeling theory is to integrate analytical methods directly into the CAD and simulation environment and thereby give the designer maximal insight, efficiency, and power

• An integrated approach to parametric design that combines analytical engineering sciences directly into CAD and further uses simulation for design optimization

• Advantages

The resulting integrated parametric designs are elegant, efficient, economical, optimized, and easily adapt to change

• Key concept

A parametric model is the solution to a design problem

ESSENTIAL COMPONENTS OF PARAMETRIC MODELING THEORY• Understand problem at hand

List design constraints and assign nomenclature

Draw freehand sketches as needed to describe the problem

List relevant physics (e.g. geometry, materials, statics, dynamics, thermal)

• Specify design intent

Determine design problem

Determine key parameters that will drive design

Determine which parameters will be computed or optimized

• Build parametric model with analytical methods

• Confirm and adjust model with simulation
