Quick Answer
For SolidWorks modelling, buy the dock in this order: a Thunderbolt or USB4 dock with full display bandwidth first (to drive a high-resolution monitor at 60Hz), then 65-100W power delivery, then extra USB and Ethernet. A R2,500-R4,500 Thunderbolt dock is the must-have; cheap USB-C hubs that throttle the display under CAD load are the trap to skip.
Must-Have: Display Bandwidth For CAD
SolidWorks modelling pushes a detailed 3D viewport, so the dock must deliver full, stable display bandwidth without throttling when the GPU is busy. A Thunderbolt or USB4 dock provides the headroom to run a 1440p or 4K monitor at 60Hz alongside peripherals, where a budget USB-C hub may drop frames or refresh under load. This is the must-have, because a stuttering CAD viewport through a weak dock wastes the workstation laptop you bought. Budget R2,500-R4,500 for a dock that holds the display solid.
Nice-To-Have: Power And Connectivity
After display, prioritise power delivery so the workstation laptop charges while it renders, since CAD work drains a battery fast; look for 90-100W on a powerful machine. Gigabit Ethernet gives stable access to PDM vaults and network drives where shared model files live. Several USB-A and USB-C ports cover a 3D mouse, keyboard and external storage for large assemblies. These matter, but they sit below display bandwidth in the buying order for a smooth modelling experience.
Skip: Underspecced Hubs And Gimmick Ports
Skip cheap multi-port USB-C hubs marketed as docks; they share bandwidth and choke a CAD display when storage or the GPU is active. Skip SD readers and extra HDMI outputs you will not use on a single-monitor modelling setup. The discipline is simple: pay for a Thunderbolt or USB4 dock with confirmed display headroom and power, and ignore feature lists that pad the price without helping a SolidWorks viewport stay smooth.
FAQ
What dock do I need for SolidWorks modelling?
A Thunderbolt or USB4 dock at R2,500-R4,500 with full display bandwidth to drive a 1440p or 4K monitor at 60Hz without throttling. Budget USB-C hubs choke a CAD viewport under load.
How much power delivery does a CAD laptop dock need?
Around 90-100W on a powerful workstation laptop, because SolidWorks drains the battery fast while modelling. The dock should charge the laptop while it renders.
Why avoid cheap USB-C hubs for CAD?
They share bandwidth and drop display frames or refresh when storage or the GPU is busy. A Thunderbolt or USB4 dock keeps the 3D viewport smooth under load.
Choose a Thunderbolt or USB4 dock at Evetech with confirmed 4K60 output and 90-100W power, so your SolidWorks viewport stays smooth on a single cable.
