SOLIDWORKS Interference detection: How to Identify, Fix, and Avoid interference?

Introduction

Interference detection is the process of finding and fixing errors or issues with your design. It can be difficult to know where to start when your model starts to feel like a minefield of problems. In this article, you will learn how SOLIDWORKS interference checking tools can help you find and fix many common mistakes in your models.

4 Steps to fix interference detection in SOLIDWORKS

SOLIDWORKS has a built-in interference detection tool which can be used to identify potential interferences between mating parts. The steps to check for interference are as follows:

1. Open the assembly file and select the mating parts to be checked for interference.
2. Click on the interference detection tool under the Assembly toolbar.
3. The interference detection window will open up. Select the appropriate options and click on the OK button.
4. SOLIDWORKS will check for interferences between the selected parts and generate a report.

In the below example we will be analyzing component interference’s found within the assembly interference, and  detection analyzes geometry.

How to identify Interference detection in SOLIDWORKS?

First, Interference detection is found within “Evaluate tab” in tools.

“Click Tools –> Evaluate –> Interference Detection”

Note: It is easy to see interference’s but sometimes it can be difficult to determine. By default, the selected component will be assembly. You can delete it by right-clicking on the name of the assembly and delete.

To select new parts, click on the desired area in the Graphics window.

Here, the components are overlapped as shown in below assembly image.

How to solve it?

To solve we need to calculate interference’s within the entire assembly or specify components and then calculate for entire component.

As a result, the interference detection highlights the overlapping volumes of both components as transparent object.

Next, check the mates associated with the component using view mates tool option. Now we know the distance between the two interfering components.

Adjust the dimension & check for interference till you can see there are no longer any interference between the selected components. After making all the corrections, functionality between the components is  .

SOLIDWORKS had easy to change the distance and the overlapping issues have been resolved.

Interference detection was great for static interference’s when it comes to dynamic collisions we need to use a different tool the move component command contains a collision detection feature will check collisions between all components.

Interference detection can be useful to ensure that the component has the desired level of motion.

How to avoid Interference and enhance detection results?

There are a few things you can do to help ensure accurate interference detection results:

1. Properly define all mating surfaces.
2. Place all components in the correct orientation.
3. Use mating pairs wherever possible.
4. Check your results carefully, and correct any errors.

Conclusion:

SOLIDWORKS interference detection helps you identify and fix problems with your designs before they cause issues during manufacturing.

In this article, we looked at the root-cause of interference and how to fix it. If you need any help with interference detection or any other SOLIDWORKS features, contact our technical experts for immediate assistance.
