The most significant constraint is export control . While users can model complex geometry, exporting to professional formats (DWG for CAD, IFC for BIM) requires a Go subscription, effectively creating a "walled garden" for free users.
Historically, professional 3D modeling required powerful desktop workstations, a mouse, and extensive training. SketchUp disrupted this paradigm in the 2000s with an intuitive "push-pull" interface. In 2021, Trimble released a dedicated iPad app, available in both a free tier and a paid "SketchUp Go" tier. This paper argues that SketchUp Free for iPad successfully lowers the barrier to entry for conceptual 3D design, particularly for students, hobbyists, and early-stage professionals, despite significant feature limitations compared to its desktop counterpart. sketchup free ipad
