💡 Hint

Common Mistakes

Using incorrect method names like StartDraftAnalysis or LaunchDraftTool.

The method RunDraftAnalysis() starts the draft analysis tool in SolidWorks.

Complete the code to set the draft angle to 5 degrees.

Solidworks

draftFeature = model.FeatureByName("Draft1")
draftFeature.[1] = 5

Drag options to blanks, or click blank then click option'

AAngle

BSetAngle

CSetDraft

💡 Hint

Common Mistakes

Using method names instead of property names like SetAngle or SetDraft.

The property Angle sets the draft angle value in degrees.

3fill in blank

hard

Fix the error in the code to retrieve the draft direction vector.

Solidworks

draftFeature = model.FeatureByName("Draft1")
direction = draftFeature.[1]

Drag options to blanks, or click blank then click option'

AGetDirectionVector

BGetDraftDirection

CDirection

💡 Hint

Common Mistakes

Calling a property as a method with parentheses.

The draft direction is accessed as a property DraftDirection, not a method.

4fill in blank

hard

Fill both blanks to set the draft face and enable the draft analysis.

Solidworks

face = model.[1]("Face1")
draftFeature.[2] = True

Drag options to blanks, or click blank then click option'

AGetEntityByName

BSelectFace

CEnableDraftAnalysis

DIsDraftEnabled

Attempts:

💡 Hint

Common Mistakes

Using incorrect method names or properties that do not exist.

Use GetEntityByName to get the face object and set IsDraftEnabled to True to enable draft analysis.

5fill in blank

hard

Fill all three blanks to create a draft analysis report with a threshold angle.

Solidworks

report = model.[1](threshold=[2])
report.[3]()

Drag options to blanks, or click blank then click option'

ACreateDraftReport

B5

CGenerate

DStartReport

💡 Hint

Common Mistakes

Using wrong method names or forgetting to call generate.

Use CreateDraftReport with a threshold angle of 5 degrees, then call Generate() to produce the report.

Practice

1. What is the main purpose of Draft Analysis in SolidWorks molding?

easy

A. To measure the thickness of the part

B. To design the mold cooling channels

C. To calculate the weight of the molded part

D. To check if part surfaces have the correct angles for easy mold release

Solution

1. Step 1: Understand Draft Analysis purpose

   Draft analysis is used to verify if surfaces have the right draft angles to allow easy removal from the mold.

2. Step 2: Compare options with purpose

   Only To check if part surfaces have the correct angles for easy mold release matches this purpose; others relate to different mold design aspects.

3. Final Answer:

   To check if part surfaces have the correct angles for easy mold release -> Option D

4. Quick Check:

   Draft analysis = check draft angles [OK]

Hint: Draft analysis checks angles for mold release [OK]

Common Mistakes:

• Confusing draft analysis with thickness measurement
• Thinking draft analysis calculates weight
• Assuming draft analysis designs cooling

2. Which of the following is the correct step to start a draft analysis in SolidWorks?

easy

A. Open the mold tool and select 'Thickness Check'

B. Select the part, then click on 'Evaluate' tab and choose 'Draft Analysis'

C. Go to 'Insert' menu and select 'Mass Properties'

D. Right-click on the part and select 'Add Material'

Solution

1. Step 1: Identify correct menu path for draft analysis

   Draft analysis is found under the 'Evaluate' tab in SolidWorks.

2. Step 2: Match options with correct path

   Select the part, then click on 'Evaluate' tab and choose 'Draft Analysis' correctly describes selecting the part, then using 'Evaluate' > 'Draft Analysis'. Others are unrelated.

3. Final Answer:

   Select the part, then click on 'Evaluate' tab and choose 'Draft Analysis' -> Option B

4. Quick Check:

   Draft analysis location = Evaluate tab [OK]

Hint: Find draft analysis under Evaluate tab [OK]

Common Mistakes:

• Confusing draft analysis with thickness check
• Looking under Insert menu incorrectly
• Trying to add material instead of analyzing draft

3. Given a part with a pull direction set incorrectly, what will the draft analysis color code likely show?

medium

A. Incorrect color coding, possibly red or no draft shown

B. No color changes, draft analysis will not run

C. Only the edges highlighted in blue

D. All surfaces green indicating good draft

Solution

1. Step 1: Understand pull direction role in draft analysis

   Pull direction defines how the mold opens; incorrect setting causes wrong draft angle evaluation.

2. Step 2: Predict color code effect

   Wrong pull direction leads to incorrect or misleading color coding, often showing red or no draft indication.

3. Final Answer:

   Incorrect color coding, possibly red or no draft shown -> Option A

4. Quick Check:

   Wrong pull direction = wrong color code [OK]

Hint: Wrong pull direction causes wrong draft colors [OK]

Common Mistakes:

• Assuming all green means good draft despite wrong pull
• Thinking edges only get highlighted
• Believing draft analysis won't run at all

4. You ran draft analysis but the colors do not match expected draft angles. What is the most likely error?

medium

A. Draft analysis was run on a 2D sketch

B. The part has no material assigned

C. Pull direction is set incorrectly

D. The computer graphics driver is outdated

Solution

1. Step 1: Identify common causes of wrong draft colors

   Incorrect pull direction is the most common cause for wrong draft color results.

2. Step 2: Evaluate other options

   No material or 2D sketch won't run draft analysis properly, but usually cause errors, not wrong colors. Graphics driver affects display but not analysis logic.

3. Final Answer:

   Pull direction is set incorrectly -> Option C

4. Quick Check:

   Wrong colors = wrong pull direction [OK]

Hint: Check pull direction first if colors seem wrong [OK]

Common Mistakes:

• Ignoring pull direction as cause
• Blaming material assignment
• Thinking 2D sketches can show draft colors

5. You want to ensure a part has a minimum draft angle of 3 degrees for molding. How do you set this in SolidWorks draft analysis?

hard

A. Set the draft angle value to 3 degrees in the draft analysis property manager

B. Change the pull direction to 3 degrees

C. Apply a 3-degree fillet to all edges

D. Increase the part thickness by 3 mm

Solution

1. Step 1: Identify how to specify draft angle in analysis

   In draft analysis, you set the minimum draft angle to check surfaces against that value.

2. Step 2: Evaluate options for setting draft angle

   Set the draft angle value to 3 degrees in the draft analysis property manager correctly describes setting the draft angle in the property manager. Others change geometry or pull direction incorrectly.

3. Final Answer:

   Set the draft angle value to 3 degrees in the draft analysis property manager -> Option A

4. Quick Check:

   Minimum draft angle set in property manager [OK]

Hint: Set draft angle in property manager, not geometry [OK]

Common Mistakes:

• Changing pull direction instead of angle value
• Adding fillets instead of setting draft angle
• Modifying thickness unrelated to draft
