I have a three-storey building drawn in 2D that I need rebuilt as a clean, watertight 3D model ready for Blender. The final file must be delivered in STP format so I can bring it straight into my workflow without extra conversion. Scope of work • Recreate all three floors true to the original plan, matching wall thicknesses, window and door openings, stairwells, and roof geometry. • Add the surrounding plot: a simple outline of the pavements and roads that frame the site. This exterior can stay low-fidelity—just basic shapes without textures or materials. • No interior materials or UVs are required; a neutral viewport look is fine. • Provide a set of isometric renders once the model is complete so I can review overall proportions and catch any errors before I sign off. Acceptance criteria 1. Model opens in Blender via the supplied STP with correct scale (metric) and no missing faces or reversed normals. 2. Each floor is separable by object/layer for easy isolation. 3. Roads and plot outline align accurately with the building footprint. 4. Four isometric screenshots (NE, NW, SE, SW) supplied as PNGs at 1920×1080. Please work in whichever CAD or modeling package you prefer—Rhino, SolidWorks, Revit, or similar—as long as the exported STP imports cleanly on my side. Let me know your estimated turnaround and any clarification you need on the 2D drawings, and we can get started right away.
