3D Roof Model Preparation for Large-Scale Printing

About the project

NOTE: This is not a rendering project. We need a CAD/mesh specialist who can repair or rebuild disconnected structural geometry and deliver watertight, print-ready STL files with fully solid beams. Project Brief: Prepare Structural Roof Model for 3D Printing Project Title Urgent Preparation of Revit/AutoCAD Structural Roof Model for Large-Scale 3D Printing Project Overview We have an architectural model available in both Autodesk Revit and AutoCAD 3D formats. The model consists mainly of: Curved structural beams Secondary truss and support members Roof sheet or roof surface Supporting bases The existing files were not originally prepared for 3D printing. The structural elements are not properly connected, and parts of the model are currently represented as disconnected meshes, surfaces, blocks, or hollow members. The model must be repaired and, where necessary, partially remodelled to produce a strong, printable 3D model while preserving the original architectural appearance. Critical Requirement: Solid Structural Beams All structural beams, trusses, tubes, and support members must be created as fully solid geometry. The final model must contain: No hollow beams No hollow tubes No hollow internal structural members No open-ended beam profiles No thin surface-only representations of structural members Each beam or structural member must have a completely filled cross-section suitable for FDM 3D printing. The roof sheet may remain a shell with controlled thickness, but all supporting beams and structural members must be solid. Scope of Work The freelancer will be responsible for: Reviewing both the Revit and AutoCAD 3D files and selecting the most suitable source file. Repairing or rebuilding disconnected beams, trusses, and structural members. Converting all beams and supporting structures into solid, non-hollow geometry. Properly connecting all intersecting structural members. Repairing gaps between: Main beams and secondary members Truss members Roof and supporting structure Structural members and supporting bases Thickening beams where required to ensure that they remain strong and printable. Giving the roof sheet a suitable physical thickness. Removing: Floating geometry Duplicate elements Overlapping faces Internal unwanted surfaces Non-manifold geometry Open edges Unconnected mesh elements Producing a fully watertight final model. Dividing the model into practical printing sections if required due to its approximate 140 × 50 cm physical size. Designing clean connection points between separate sections where required. Checking the completed model in slicing software before delivery. Permitted Redesign The original architectural design and external appearance must be maintained. However, controlled redesign or reconstruction is permitted where technically necessary to: Connect structural members Replace unusable mesh geometry Convert hollow beams into solid members Increase the thickness of fragile elements Strengthen connection points Prepare the roof for printing Split the model into printable sections Create assembly joints Make the geometry watertight Any major visible design change should be approved before implementation. Printing and Assembly Requirements The model is intended for FDM 3D printing. The freelancer should prepare the model based on the actual printer build volume and recommend the most suitable division strategy. Where the model must be separated, the freelancer should include suitable assembly features such as: Alignment pins Male and female connectors Sleeves Slots Internal locating joints Clearly numbered sections The connections should make assembly straightforward while minimizing visible seams. The model should not simply be cut into sections without alignment or assembly consideration. Geometry Requirements The completed model must: Use millimetres as the working and export unit Maintain the correct architectural proportions Have an approximate assembled size of 140 cm × 50 cm Include solid beams and solid structural members Have no hollow structural elements Have no open surfaces Have no floating objects Have no non-manifold edges Have no intersecting or duplicate internal faces Be watertight Be suitable for slicing and FDM printing Maintain sufficient strength for handling and assembly Roof Sheet Requirements The roof sheet should: Maintain the original curved shape Have actual printable thickness Be properly connected or positioned relative to the supporting structure Be divided into suitable sections if required Not remain as a zero-thickness surface Be printable without losing the intended architectural form The freelancer should propose a suitable roof thickness based on the final model size and printing method. Deliverables The freelancer must provide: Print-ready STL files Separate and clearly named by section where applicable Correctly oriented where practical Using millimetres Complete assembled STL or reference model Showing how all sections fit together Editable source file, preferably in one or more of the following formats: Revit AutoCAD DWG STEP Fusion 360 Rhino Blender Slicer validation screenshots showing: Successful slicing Final overall dimensions All beams visible No missing structural members No geometry errors Proposed print orientation Assembly reference Numbered parts Simple assembly diagram or screenshots Identification of connection points Brief work summary stating: Which elements were rebuilt Which beams were thickened How hollow members were converted to solid members How the model was divided Final model dimensions Any recommended printing settings or precautions Acceptance Criteria The work will be accepted when: The original architectural form is maintained. The assembled model is approximately 140 cm long and 50 cm wide. All beams and structural members are fully solid. There are no hollow tubes or hollow supporting structures. All required structural members are properly connected. The roof has a suitable printable thickness. The model is watertight. All sections successfully open and slice in standard slicing software. No essential beams disappear in the slicer preview. The divided parts include practical alignment or assembly features. The final files are ready for FDM 3D printing.
