Test Am

Every SOLIDWORKS user runs into the same problem eventually. An assembly that used to open in a few seconds now takes minutes. A simulation that used to finish overnight now takes two days. And the laptop that functioned perfectly a year ago suddenly can’t keep up with today’s demands.  

The usual fix is to buy a bigger, more expensive computer. But that’s slow, costly, and outdated again within a year or two. Hosted SOLIDWORKS cloud solutions take a different approach: instead of upgrading the computer under someone’s desk, they run SOLIDWORKS on powerful servers in a data center and simply stream the screen back to whatever device the person is using.  

Let’s explore how cloud solutions address two of the toughest tasks in SOLIDWORKS: large assemblies and simulations. 

Why Big Assemblies and Simulations Slow Your Computer Down 

SOLIDWORKS’s own system requirements call for at least 16 GB of memory (32 GB recommended) and a graphics card with an officially certified driver, and that’s just for general use, not heavy assemblies. As a model grows, three things happen at once: 

• The processor becomes a bottleneck. Most of the processes in SOLIDWORKS, such as rebuilding a model or navigating the feature tree, are executed on a single processor core at a time. Therefore, the speed of an individual core is more crucial than having multiple cores. 
• The graphics card has to redraw everything. Every time you rotate, zoom, or shade a large assembly, that’s real-time graphics work. A regular gaming graphics card can run SOLIDWORKS, but it isn’t checked against SOLIDWORKS’s official list of tested cards and drivers, which is often why people see flickering, glitchy shading, or crashes. 
• Simulation needs a completely different setup. SOLIDWORKS Simulation studies, such as stress, heat, or vibration analysis, rely more on memory and processing power than everyday modeling. Simulation benefits from a high-clock-speed processor with more cores, at least 32 GB of memory (64 GB or more for large studies), fast solid-state storage, and a certified graphics card for reviewing results. More cores don’t always mean a proportionally faster result. Some parts of a simulation calculation can’t be split across multiple cores no matter how many you add, which is exactly why simply buying a bigger machine doesn’t always pay off. 

 In practice, that means the workstation spec needed for a team’s heaviest work is far higher than what most engineers need day to day. Buying that spec for everyone is expensive, and buying it for only a few people creates bottlenecks. 

What Does “SOLIDWORKS in the Cloud” Actually Mean? 

It’s important to distinguish between two concepts that people often confuse when discussing “SOLIDWORKS in the cloud.” 

The first is a hosted virtual desktop. This setup provides a complete, familiar copy of SOLIDWORKS (using your existing license) that runs on a powerful computer located in a data center. You can access this virtual desktop from a laptop, thin client, or Mac. 

The second is Dassault Systèmes’ own 3DEXPERIENCE Works Simulation, which lets you send a specific, very heavy simulation job to Dassault’s own cloud computers while you keep modeling on your regular machine. Dassault describes this as a way to free up your own computer while a study runs in the background, so results are ready when you check back, and it lets you run several simulation scenarios at the same time instead of one after another. 

These two things aren’t competing with each other; they solve different problems. A hosted cloud desktop for SOLIDWORKS gives every engineer consistently strong performance for everyday modeling, big assemblies, file management, and routine simulation. Dassault Systèmes’ cloud simulation tools can provide extra computing power for occasional large or complex studies that exceed the practical limits of a local or virtual workstation. 

How the Cloud Handles Large Assemblies 

1.  The graphics work happens on a data center GPU, not your laptop 

On a hosted SOLIDWORKS desktop, your model isn’t drawn by your laptop at all.  It’s drawn by an NVIDIA GPU in the data center, allocated to your desktop through NVIDIA vGPU, and only the finished image is streamed to your screen.  

Citrix HDX 3D Pro handles this delivery. It renders SOLIDWORKS’s OpenGL graphics on the server’s GPU and streams compressed frames to your device. That’s why a thin client or a basic laptop can rotate a heavy assembly smoothly. Network latency between the user and the data center matters more than raw bandwidth.

2. Memory and processing power grow with your project 

Local computers are bought once, based on a guess about future needs. A cloud desktop can simply be given more memory, more processing power, or a stronger
