When rotating viewport 3D models for foundation work, use the viewport’s navigation tools—like middle mouse button drag or assigned shortcuts—to adjust angle and perspective.
This lets you examine the foundation’s sides, top, or underground sections to verify alignment, depth, or connections to footings/slabs, which is key for structural accuracy.
For software like Revit or SketchUp, use the “Orbit” tool (often Shift+Middle Click) for smoother rotation, and zoom in to focus on details without losing context.
