Ever felt the need to add a center of mass point to your SOLIDWORKS part, but don’t know how to? You’re in the right place. In this guide, you’ll learn how to add center of mass to a part in SolidWorks. Introduction to the Center of Mass (COM) The center of Mass (COM) is a fundamental characteristic that is the mean location of the mass of a body. It is important to understand COM in order to study a part’s stability, balance, and inertia. Whether you are designing a very sophisticated assembly for aerospace or a simple bracket for a consumer product, the COM helps you to predict how the part will behave under different forces and conditions. Although SOLIDWORKS will calculate the COM for you automatically, wouldn’t it be convenient to have a permanent visual reference point within your part file? That is where a simple VBA macro comes in. This article will guide you through a SOLIDWORKS macro that adds a Center of Mass point for you automatically. It’s gonna be easy to refer to in drawings, sketches, and assemblies alike. Why Use a Macro for This? SOLIDWORKS includes calculators for the Center of Mass, but they require several clicks and do not create a persistent feature in the tree. That can be annoying if you are going to need to refer to the COM frequently. A macro removes that step. With one click, you can: The VBA Macro: Your Toolkit The following VBA macro is a quick fix to create a COM point. We will make sure that you have all the requirements set up before you write the code. System Requirements Pre-requisites For the macro to function correctly, ensure your part file is in the following state: How to Use the Macro? To use the Macro, you don’t really have to be an expert programmer: The VBA Code Macro You can download the macro from here. Customizing and Expanding the Macro This is a good place to begin a macro, but with the SOLIDWORKS API, there are an incredible number of possibilities. You can use this macro and modify it to: Conclusion With this simple VBA macro, you can automate your SOLIDWORKS process and provide your part designs with a professional touch. Center of Mass is an important property, and having a permanent visual reference to it can save your time, improve the accuracy, and make your design decisions simpler. Start with this code, experiment with the SOLIDWORKS API, and identify areas where you can further automate your design process. hopefully you have understood how you can add center of mass to a part in SolidWorks within a few minutes.
