It is recommended to upload 3D models and 2D drawings to facilitate simultaneous evaluation of structure, dimensions, tolerances, materials, surface treatment and inspection requirements:
- 3D files: STEP / STP, IGES / IGS, Parasolid, STL
- 2D drawings: DWG, DXF, PDF, recommended including critical dimensions, tolerances, datums and technical requirements
- Supporting information: BOM, assembly relationship, stress position, appearance surface definition, inspection specifications or sample photos
If the project is in the prototype validation, functional testing, ground testing or low-volume pilot production stage, please synchronize the version number, quantity, material grade, test report requirements and target delivery date so that engineers can complete the DFM review and quotation faster.
