The short answer: AutoCAD for 2D drafting is a light application that runs well on modest hardware, while SOLIDWORKS with large assemblies is one of the most demanding desktop workloads in any office. Spec the machine to the actual work, not the software name on the box. And because CAD files are large, the file server and network deserve the same attention as the workstation.
Here are the real numbers, tier by tier.
What are realistic workstation specs and costs by workload?
| Entry: 2D drafting | Mid: 3D modeling | Heavy: large assemblies | |
|---|---|---|---|
| Typical use | AutoCAD 2D plans, redlines, detailing | 3D AutoCAD, SOLIDWORKS parts and small assemblies | SOLIDWORKS assemblies of 1,000+ components, simulation, rendering |
| CPU | Recent Core i5 or Ryzen 5, high clock speed | Core i7 or Ryzen 7, high boost clock | Core i9, Ryzen 9, or Xeon/Threadripper class, fastest single-core you can buy |
| RAM | 16 GB | 32 GB | 64 GB, more for simulation |
| GPU | Integrated or entry discrete | Certified pro GPU, entry tier (RTX A400/A1000 class) | Certified pro GPU, mid to high tier (RTX A2000 through A4500 class) |
| Storage | 512 GB NVMe SSD | 1 TB NVMe SSD | 1 TB+ NVMe SSD, second drive for local cache |
| Typical cost | $900 to $1,500 | $1,800 to $3,000 | $3,500 to $6,000+ |
Two spec details matter more than the model names. First, CAD modeling is still largely single-threaded, so a CPU with a high clock speed beats one with more cores at the same price for everyday modeling. Cores only pay off in rendering and simulation. Second, an NVMe SSD is not optional at any tier. Opening a large assembly from a spinning disk can take several minutes that an SSD does in seconds.
For current minimums, check the vendors directly rather than a reseller spec sheet: Autodesk publishes AutoCAD system requirements per release, and Dassault publishes SOLIDWORKS system requirements along with its certified hardware database. As of recent releases both list minimums well below what feels good in daily use, which is why the table above reflects working specs, not survival specs.
Why does the graphics card question keep coming up with SOLIDWORKS?
Because Dassault draws a hard line that Autodesk does not. SOLIDWORKS is only supported on certified professional GPUs with certified driver versions, which in practice means NVIDIA RTX A-series and similar workstation cards. A GeForce gaming card, even an expensive one, will usually run the software and can benchmark impressively, but you are in unsupported territory. When you hit graphical corruption, missing edges, or crashes, the first support answer is to install a certified card and driver.
Our honest framing for buyers: the GeForce route saves several hundred dollars per seat and many small shops run it without incident. The certified card buys you stability, supportability, and one less variable when something breaks. For a business paying engineering salaries, we recommend certified cards for SOLIDWORKS seats and consider GeForce acceptable only for AutoCAD-only machines, where Autodesk is more permissive.
What do the file server and network need to look like?
CAD files are big, and SOLIDWORKS assemblies are worse than big, they are webs of linked part and drawing references that all load together. That shapes the infrastructure:
- Wired gigabit to every CAD seat, minimum. Wi-Fi is fine for email, not for opening a 400 MB assembly from the server. For teams pushing very large models or point clouds, 2.5 or 10 gigabit between the server and switch is a cheap upgrade that users feel immediately.
- A file server with SSD storage for the active project share. CAD load times track storage and network speed directly.
- Keep working files off sync clients. OneDrive and SharePoint sync break linked references and create conflicting copies when two people touch the same assembly. Use them for issued PDFs, not the live vault.
- PDM when the team grows. At roughly three or more concurrent SOLIDWORKS users, SOLIDWORKS PDM or a similar vault stops the silent-overwrite problem and adds real revision control. PDM runs on a Windows server with SQL Server underneath, the same stack we manage for Jonas and other construction software.
Do you need an on-premise server, or can this live in Azure?
For the file share itself, an office server still wins for CAD because the working files sit one gigabit hop from the workstations. A cloud file share accessed over the internet adds latency that CAD users feel on every open and save.
Azure earns its place in three roles: hosting the PDM database and license servers when you want fewer boxes in the office, Azure File Sync or backup as the off-site copy of the CAD share, and GPU-enabled cloud workstations for remote users. Many of our construction and engineering clients run a hybrid: local file server for speed, Azure for backup, identity, and remote access.
How should remote and field CAD users work?
Two patterns work, one does not.
Remote into the office workstation. The engineer’s powerful desktop stays in the office, and they connect from anywhere over a modern remote display protocol. Files never leave the office network, so opens and saves stay fast. This is the cheapest good answer for occasional remote work.
Cloud workstation. A GPU-enabled virtual machine in Azure, sized like the mid or heavy tier above, with the file share in the same region. Costs more per month but scales up for a project and back down after, and works well for contractors or temporary seats.
What fails: VPN file access from a home PC. Opening assemblies directly across a VPN is slow enough to be unusable and risks corrupting files on a dropped connection. If you see this pattern in your company, it is worth fixing before it costs you a drawing set.
For field staff, buy a true mobile workstation with a professional GPU option for anyone who must open models on site, and let everyone else view issued PDFs on whatever they carry.
What does this look like with an IT partner behind it?
Braintek supports AutoCAD and SOLIDWORKS environments alongside Jonas, Azure, and SQL for construction and engineering firms across Houston and Dallas-Fort Worth, so the workstation spec, the file server, the PDM database, and the backup are one accountable scope instead of four vendors pointing at each other. When a CAD seat goes down, our phones are answered in about 60 seconds, which matters when a stalled workstation is a stalled project. Our managed IT services cover the ongoing side, and our construction industry page shows how the pieces fit together for contractors specifically.
If you’re pricing new CAD hardware or a designer just complained about rebuild times again, send us your machine list and what you model. We’ll map each seat to a tier, flag which machines are worth upgrading versus replacing, and spec the server and network so the fast workstations aren’t waiting on a slow share.
