Once upon a time, there was only a handful of commercially available CAD software. Today, however, there are so many CAD software packages out there, that selecting the best one for your application can be a headache. Some may argue that some CAD software tower above the rest in terms of functionality, and so the selection process is easy. However, even at the top, numerous software packages have varying ranges of capabilities for various industries. So how does one go about selecting the perfect package for their application? We at Scan2CAD know how confusing the selection process can be, therefore to make the task easier for you, we regularly create intuitive comparison articles on the top CAD software packages available today.

In this article, we will be comparing two packages that require little introduction, SolidWorks from Dassault Systems and Onshape from PTC Inc. On the surface, SolidWorks and Onshape are similar 3D CAD modeling software. However, they both have certain crucial differences. In this article, we will be exploring these software packages’ history, capabilities, and users. We will also comparatively analyze their capabilities, features, licensing options, and compatibility with different operating systems, all in a bid to simplify the selection process.

Onshape

The histories of SolidWorks and Onshape are linked by an interesting fact. Onshape was co-founded by Jon Hirschtick in 2012, the same man who co-founded SolidWorks 19 years earlier. He co-founded Onshape with John McEleney, who was also a former SolidWorks CEO, and four others. Onshape was founded in Massachusetts as Belmont technology, a name that was later changed to Onshape. The company received its first round of funding in the tune of $9 million from North Bridge venture partners and Commonwealth. In 2015, following extensive testing by thousands of CAD professionals, Onshape released its android app. Later that same year, the Onshape App Store was launched, offering cloud-based CAM, simulation, and rendering apps among others. Between April and May 2016, Onshape introduced its educational plan with a free version of the software for students. It also released an open-source programming language, known as Feature Script, for creating and customizing CAD features. In October 2019, Onshape was acquired by PTC, software giants and makers of Creo, for $470 million.

What does Onshape do?

Onshape is a cloud-based 3D CAD modeling software that unites CAD, data management, and collaboration. It is one of the first software as a service (SaaS) CAD product development platforms. As it is delivered via a SaaS model, Onshape does not require any downloads, installations, or updates. All you require to access Onshape is a compatible web browser and an internet connection as all Onshape’s features are available over the internet.  This is one of the software’s most distinguishing features. Onshape is compatible with IOS, Android OS, Linux, OSX (Mac), and Windows.

Considering this software’s creators, you will probably be expecting it to have impressive features. Onshape’s features can be classified into CAD, data management, collaboration, security and audit controls, analytics and reporting, and integration and partners.

The CAD features of Onshape allow you to model individual parts as well as assemblies of various parts. You can also create highly detailed 2D working drawings containing dimensions, annotations, tables, datum, and part lists. These features also enable you to import/export various industry file formats. In addition to these, the CAD features include simultaneous sheet metal tools, intelligent custom features, standard content libraries, and configuration options.

Data management. With the product data management (PDM) features of Onshape, you do not need a separate PDM system. Using these features, you can handle release management, version control, branching and merging, and advanced workflows. These features also enable you to configure and manage a bill of materials in real-time while simultaneously creating or editing an assembly. Data management is a crucial part of the design process and getting it right is crucial to saving time and effort. 

Collaboration. Collaboration tools enable multiple users to collaborate with the lead designer in real-time. These tools enable simultaneous editing and review as you work. Whether it is with a customer, a business associate, your company, your suppliers or your design team, you can securely share your projects for live chat, commenting, and review. You can also add comments on a project and assign tasks to different people. For greater control, access may be limited to viewing, commenting, or editing models.

Security and audit controls. Few platforms offer as much security and audit control as Onshape. To begin with, all your files are securely stored in the cloud. Furthermore, you can protect your design data from unauthorized access using role-based access controls, AES-256 and TLS v 1.2 encryption, two-factor authentication, and comprehensive audit logs. Any edit, modification, or alteration on your design is tracked and recorded for review, and, if necessary, reversing.

Analytics and reporting. With analytics features, you can properly monitor projects’ status with the activity overview, release, project, and user dashboards. You get in-depth analysis and reports on documents, projects, and users. You also get a complete design history and change log, release reporting, and news feed styled activity reports.

Integration and partners. Onshape allows you to make up for its limitations through integrations and partners. You can extend the functionality of Onshape using PLM, ERP, CAM, and simulation add-ons from the Onshape App Store. All Onshape integrated cloud partner apps have unified purchase, licensing, and sign-on mechanisms. Like Onshape, these apps do not require download, installation, or updates.

SolidWorks

SolidWorks was released in November 1995 as the flagship product of its parent company, SolidWorks Corporation. SolidWorks Corporation was founded two years earlier in December 1993, by MIT graduate, Jon Hirschtick, with the goal of building an easy-to-use, affordable, and windows compatible 3D CAD software. After two years of hard work by a team of engineers, and a $1 million investment, SolidWorks was born. The software made so much impact in the world of CAD that in 1997, just two years after its release, SolidWorks was acquired by Dassault Systems for $310 million in stock ($497 million in today’s money). Jon Hirschtick remained with the company in various capacities for 14 years, before leaving to co-found Onshape. Over the years, 28 versions of SolidWorks have been released. The latest, SolidWorks 2020, was released on the 18th of September, 2019.
