I need a precise 3D half-section of a residential flat, presented in a clean, technical rendering style. The focus is limited to the bedrooms and bathrooms, so every wall, fixture, and built-in element in those zones must be modeled accurately. I will supply the 2D floor plan with dimensions; you translate that into a well-structured 3D model, slice it at mid-height, and produce: • One native model file (Revit, SketchUp, or similar) with organized layers/groups. • High-resolution line-shaded renders (PNG or PDF) showing plan, elevation, and the half-section perspective. • A short walkthrough animation is welcome if it helps illustrate spatial relationships, but it’s optional. Clarity is critical—labels, consistent line weights, and true dimensions should make the drawing suitable for coordination and basic technical review. Keep materials simple; I’m prioritizing geometry and layout over photoreal textures. Let me know your preferred tool, estimated turnaround, and any questions about the plan set so we can start right away.
