Interference detection in Solidworks - Dashboard Guide

Dashboard Mode - Interference detection

Goal

Find out if parts in an assembly overlap or interfere with each other to avoid design problems before manufacturing.

Sample Data: Assembly Parts and Interference Status

Part A	Part B	Interference Volume (mm³)	Interference Detected
Gear	Shaft	0	No
Cover	Base	15	Yes
Pin	Bracket	0	No
Spring	Rod	5	Yes
Handle	Body	0	No
Lever	Pin	8	Yes

Dashboard Components

• KPI Card: Total Interferences
  Formula: Count of rows where Interference Detected = 'Yes'
  Result: 3
• Bar Chart: Interference Volume by Part Pair
  Shows interference volume for each pair of parts.
  Data: Part pairs on X-axis, Interference Volume on Y-axis.
  Bars for pairs with zero volume show no interference.
• Table: Detailed Interference List
  Shows all part pairs with their interference volume and detection status.
  Allows sorting by volume or part names.

Dashboard Layout

+----------------------+---------------------------+
| Total Interferences  | Interference Volume Chart |
|       (KPI)          |       (Bar Chart)          |
+----------------------+---------------------------+
|          Detailed Interference List Table           |

Interactivity

User can filter by Interference Detected status (Yes/No) to update all components:

• KPI card updates total count of interferences.
• Bar chart shows volumes only for filtered pairs.
• Table lists only filtered rows.

Sorting the table by volume or part names updates the table only.

Self Check

If you add a filter to show only Interference Detected = Yes, which components update and what changes?

• KPI card updates to show 3 total interferences.
• Bar chart shows bars only for Cover-Base, Spring-Rod, and Lever-Pin pairs.
• Table lists only these three pairs with their volumes.

Key Result

Dashboard shows interference detection results for assembly parts with counts, volumes, and detailed list.

Practice

1.

What is the main purpose of interference detection in SolidWorks assemblies?

easy

A. To create exploded views automatically

B. To measure the weight of the assembly

C. To calculate the cost of materials

D. To find overlapping parts that may cause design issues

Solution

1. Step 1: Understand interference detection function

   Interference detection checks if parts overlap or interfere in an assembly.

2. Step 2: Identify the main goal

   The goal is to find overlapping parts that could cause problems in design or manufacturing.

3. Final Answer:

   To find overlapping parts that may cause design issues -> Option D

4. Quick Check:

   Interference detection = Find overlapping parts [OK]

Hint: Interference detection finds overlapping parts fast [OK]

Common Mistakes:

• Confusing interference detection with cost calculation
• Thinking it measures weight or creates views
• Assuming it fixes the design automatically

2.

Which of the following is the correct step to start interference detection in SolidWorks?

Assembly > Evaluate > Interference Detection

easy

A. Open the drawing, then go to View tab and select Interference Detection

B. Open the part, then go to Features tab and select Interference Detection

C. Open the assembly, then go to Evaluate tab and select Interference Detection

D. Open the assembly, then go to Insert tab and select Interference Detection

Solution

1. Step 1: Locate Interference Detection in SolidWorks UI

   Interference Detection is found under the Evaluate tab in an assembly document.

2. Step 2: Confirm correct workflow

   You must open an assembly, then go to Evaluate > Interference Detection to start the tool.

3. Final Answer:

   Open the assembly, then go to Evaluate tab and select Interference Detection -> Option C

4. Quick Check:

   Evaluate tab in assembly = Interference Detection start [OK]

Hint: Start interference detection from Evaluate tab in assembly [OK]

Common Mistakes:

• Trying to run interference detection in part or drawing mode
• Looking under Insert or Features tabs incorrectly
• Not opening an assembly first

3.

Given an assembly with three parts where Part A overlaps Part B by 2 mm and Part B overlaps Part C by 0 mm, what will the interference detection report?

medium

A. It will report interference between all three parts

B. It will report interference between Part A and Part B only

C. It will report interference between Part B and Part C only

D. It will report no interference at all

Solution

1. Step 1: Analyze overlap distances

   Part A overlaps Part B by 2 mm, so interference exists there. Part B and Part C have 0 mm overlap, so no interference.

2. Step 2: Determine interference report

   Interference detection reports only actual overlaps, so it reports interference between Part A and Part B only.

3. Final Answer:

   It will report interference between Part A and Part B only -> Option B

4. Quick Check:

   Overlap > 0 mm = interference reported [OK]

Hint: Only overlapping parts show interference [OK]

Common Mistakes:

• Assuming zero overlap counts as interference
• Thinking all parts interfere regardless of distance
• Confusing interference with proximity

4.

In SolidWorks interference detection, a user runs the tool but no interferences are found, yet parts visibly overlap. What is the most likely cause?

medium

A. The user forgot to check 'Include Coincident Faces' option

B. The assembly file is corrupted and cannot detect interference

C. The parts are in different configurations

D. The interference detection tool only works on parts, not assemblies

Solution

1. Step 1: Understand interference detection options

   Interference detection has an option 'Include Coincident Faces' that detects touching or overlapping faces.

2. Step 2: Identify why visible overlap is missed

   If this option is unchecked, touching or coincident faces may not be reported as interference, causing missed detection.

3. Final Answer:

   The user forgot to check 'Include Coincident Faces' option -> Option A

4. Quick Check:

   Include Coincident Faces option affects detection [OK]

Hint: Check 'Include Coincident Faces' to catch touching overlaps [OK]

Common Mistakes:

• Assuming file corruption causes detection failure
• Thinking interference detection works only on parts
• Ignoring configuration differences

5.

You have a complex assembly with multiple subassemblies. You want to detect interference only between parts in different subassemblies, ignoring interferences inside each subassembly. How can you configure interference detection to achieve this?

hard

A. Use the 'Treat Subassemblies as Parts' option to detect interference only between subassemblies

B. Run interference detection separately on each subassembly and combine results manually

C. Disable interference detection and use collision detection instead

D. Use the 'Include Coincident Faces' option to filter interferences inside subassemblies

Solution

1. Step 1: Understand subassembly interference options

   SolidWorks interference detection has an option 'Treat Subassemblies as Parts' which treats each subassembly as a single part.

2. Step 2: Apply option to detect only between subassemblies

   By enabling this option, interference detection ignores internal interferences inside subassemblies and reports only between subassemblies.

3. Final Answer:

   Use the 'Treat Subassemblies as Parts' option to detect interference only between subassemblies -> Option A

4. Quick Check:

   'Treat Subassemblies as Parts' filters internal interferences [OK]

Hint: Enable 'Treat Subassemblies as Parts' to focus on inter-subassembly interference [OK]

Common Mistakes:

• Running detection separately and missing combined interferences
• Confusing collision detection with interference detection
• Misusing 'Include Coincident Faces' for this purpose
