The 5 Best Parametric Modeling Software Products of 2024

Updated Apr 12, 2024
Parametric Modeling

Parametric modeling software products are not new in computer-aided design (CAD). Introduced in 1988 with the launch of PTC’s Pro/ENGINEER (since renamed PTC Creo), parametric modeling is still relevant and predominant in 2024, more than three decades later. From a practical point of view, this concept simplifies solid modeling and helps save a lot of valuable time. It also boasts reliability and superiority over other modeling technologies that have attempted to gain wide adoption in the CAD market. It’s no wonder that design professionals prefer it to other design methodologies. As a result, more and more CAD applications have introduced support for parametric modeling.

As originally designed, parametric modeling worked as follows: whenever a designer or engineer changed the value of a dimension or edited a particular section of the solid model, the shape of the model’s geometry would automatically update. To put it simply, the shape automatically changes when one or more parameters – such as dimensions – or the relationship between the various objects is altered. Generally, the parametric modeling functionality automated the design and revision process. Moreover, it made 3D modeling tools easily accessible with improved modeling tools, such as fillet, extrude, sketch, and so on, as part of their 3D/solid modeling projects. 

Many years on, the above description holds. And as the CAD industry has evolved, CAD software companies have learned ways to improve the parametric modeling functionality within their applications. For example, this has led to the re-imagination of the workflows that professionals utilize when creating solid models. Overall, the existence of these improvements as well as the distinct implementation of the functionality from one application to another, mean that some software programs are better than others. For this reason, this article discusses the 5 best parametric modeling software products of 2024. 

Criteria for Evaluation

Anyone can come up with a list of the best parametric modeling applications, but for the sake of transparency and to give you an understanding of the rationale behind our selection, we believe it is important to explain the criteria we used to evaluate and rank the best parametric modeling software of 2024. These include:

1. Features and Capabilities

Users often consider 3D software’s features and capabilities the foremost factor whenever they want to subscribe to or purchase a particular program. We are no different. Our list considers the various features an application offers and, by extension, what it can enable users to achieve. We acknowledge that some developers include many features in their software. Sometimes, this factor can negatively impact the user experience, as we have detailed below.

2. Compatibility and Interoperability

A good 3D software application should be capable of opening and even editing files and models created using other software. This factor promotes collaboration with design professionals who prefer other applications. 

3. Ease of Use and Learning Curve

The parametric modeling software product should not only be easy to use but also have a gradual learning curve. Combined, these attributes make the application ideal for both beginners and seasoned users. In some cases, however, developers include numerous features, which can negatively impact the ease of use. As a result, such software programs have numerous windows and commands, which may be difficult to locate.

4. Customer Support and Community Resources

The best parametric modeling software products have robust and active online forums. Here, users who encounter problems can send queries, with answers provided by either the developers’ representatives or other users. However, during our research, we found programs that did not have a vibrant online forum, forming part of the basis of their exclusion.

5. Pricing and Licensing Options

Some software applications are more expensive than others. At the same time, some developers offer their products based on a perpetual license, while others prefer the subscription route. As a result, our list encompasses a whole array of products, including those on the lower and higher end of the pricing spectrum. The inclusion stems from the fact that, though some applications may be expensive, they offer value for money because of their capabilities and features.

Top 5 Parametric Modeling Software of 2024

1. SolidWorks

SolidWorks is one of the 10 best 3D CAD software on the market. Developed and distributed by Dassault Systèmes, SolidWorks is a leading CAD and computer-aided engineering (CAE) software that enables users to create 3D models as well as 2D designs. SolidWorks streamlines communication through a cloud platform known as 3DExperience® (3DX), which brings all team members within a collaborative environment. However, this does not mean that the software is cloud-based. 

It is available for download and installation as desktop software, primarily on the Windows platform. For a detailed guide on how to download, install, and set up the software, check out our article on SolidWorks basics. (Do note, however, that you can use SolidWorks online during the free trial.
