Web Quest Lift-Rod Problem: Solid Geometry Construction with Prisms and Distance

This example visualizes a Lift-Rod–style geometric constraint in 3D by building a solid model and using geometric predicates and measurements. Students can observe how a rod/segment relationship is governed by spatial configuration when key points move or parameters change. It centers on solid geometry and measurement: defining a cuboid/prism-like structure, constructing faces and edges, and enforcing constraints using distances between points. Construction approach (from the build summary): Polygon to form face outlines (e.g., faceABHG, faceBFIH, faceCFIJ, faceACJG), Prism to generate the main 3D body, PointIn to test whether a point lies inside a given region, Distance to compute the metric quantities used for constraints, and Segment to represent rods/edges (e.g., edgeAG, edgeBH, edgeFI, edgeCJ, edgeGH, edgeHI, edgeIJ, edgeGJ). Suitable for upper secondary and early university students studying 3D geometry, geometric construction, and model-based exploration (including Web Quest activities).
