Common Mistakes to Avoid
Common Mistakes to Avoid
Buying a tool that matches your part design but not your required automation output
If you need offline robot program generation and cell validation, avoid choosing only a mechanical CAD tool—RoboDK is built specifically for offline programming with reachability and collision checking. Similarly, if your goal is multiphysics workflow automation, ANSYS Workbench’s setup-to-results automation is more appropriate than relying on CAD-only rule automation.
Underestimating learning curve for advanced workflows
Tools like Autodesk Fusion 360, CATIA, and ANSYS Workbench can have a steep learning curve when you push advanced automation, validation, or multiphysics automation. RoboDK also requires expertise for complex cell behaviors and customization, so plan onboarding time rather than expecting instant results.
Overlooking licensing/module complexity and total cost
Many commercial platforms can become expensive once you add modules or seats: Siemens NX and PTC Creo commonly require additional module/configuration investment, while SolidWorks value can drop if add-ons and simulation capabilities aren’t included up front. Autodesk Fusion 360 also varies by paid plan tier and license type, which can be confusing if you only compare base pricing.
Expecting automation/controls orchestration from tools that focus on CAD or simulation workflow
Several tools are not purpose-built for PLC/SCADA authoring or automation control logic. Siemens NX and the CAD platforms in this list provide automation design documentation and engineering backing, while robot behavior orchestration typically comes from RoboDK and validation comes from Workbench/CATIA—so choose the tool aligned to the layer you actually need.
