These mistakes show up when teams select the wrong CAD paradigm for the work they actually do.
Buying a full 3D or parametric suite when your real work is DWG-based 2D drafting
If your output is 2D plans, sections, and DWG exchanges, DraftSight and LibreCAD reduce workflow mismatch by focusing on DWG-centric 2D drafting with dimensioning and snapping. AutoCAD is the correct DWG-first choice when you must also edit legacy DWG files with full fidelity and maintain complex layers and templates.
Ignoring manufacturing associativity requirements until after toolpaths are generated
Fusion 360 generates CAM toolpaths from CAD geometry, but teams that need machining setup to remain linked to design intent should evaluate Siemens NX for its associative CAD-to-CAM workflow. This prevents redesign from breaking downstream manufacturing relationships.
Choosing cloud collaboration without checking whether your team needs server-side version control
Onshape provides server-side version control tied to every document revision and supports branching workflows, so it fits teams that review and approve changes frequently. Tools like SketchUp rely more on model sharing for iteration and may not provide the same revision-control depth for engineering change processes.
Underestimating the training cost of constraint-heavy or plugin-driven modeling
