PTC Creo Parametric – Behavioral Modeling Extension (BMX)

Creo Behavioural Modelling Extension (BMX), a potent tool in the Creo Parametric software package, enables engineers and designers to simulate and examine the behaviour of mechanical systems. For people in fields like aerospace, automobile, and consumer products where precise models of intricate systems are crucial, such as BMX, this is a helpful tool.

The Behavioural Modelling Extension is built on the Pro/TOOLKIT programming language, which enables users to build unique features, functions, and user interfaces to automate design activities. Users of BMX may develop models that are based on rules, formulas, and algorithms that can be automatically updated in response to modifications made to the design parameters.


Most designs begin with a design requirement that could include information on weight, volume, the centre of gravity, etc. You must frequently go through stressful and time-consuming iterations in order to discover a solution that satisfies these requirements. You will adjust a model, take measurements, and then continue indefinitely until you discover an acceptable answer. This results in time loss for engineers and designers and the creation of unsatisfactory goods.

Iterative design assistance is one of the main advantages of Creo Behavioral Modeling Extension. In the iterative design process, a prototype or model is made, tested, and improved over the course of several iterations. With this method, designers may rapidly find and fix design flaws, enhancing the product’s overall quality.

Design tables and parametric modeling are used in BMX to facilitate iterative design. Designers can develop design tables, which can be automatically updated when the model is improved, to generate a table of design parameters and the values associated with them. Designers may specify the connections between various design factors using parametric modeling, and then utilize these connections to build sophisticated models that can be updated automatically when the design parameters change.

All about BMX and its quick introduction

With the Creo BMX, users may specify the behaviour of a system using custom equations, and then run simulations for kinematic analysis, force analysis, and other purposes to find possible design defects and improve the effectiveness of a design.

One of the main advantages of utilizing Creo BMX is that it enables designers to simulate a system’s behavior before it is ever created, which helps reduce design time and costs. For more complex simulations, BMX also enables users to smoothly move models between other software modules like Creo Simulate and Creo Advanced Assembly.

Even individuals who are unfamiliar with the program may easily develop and alter models using the Creo BMX’s user-friendly interface. Designers may easily build complicated models and mimic their behavior thanks to the interface’s numerous tools and functionalities.
