I need a precise 3D model of a DN 250 closed-type impeller for a water pump. I will provide multiple photos and full dimensional data of the existing part; your task is to recreate it faithfully in SolidWorks 2021 and return the native SLDPRT file. The geometry must match the supplied measurements, including blade profiles, hub details, and keyway features, so the part can go straight into CAM or CFD once I have your file. If you normally work in other versions or export formats, feel free to keep a copy for yourself, but please make sure what you deliver opens error-free in SolidWorks 2021. Once I send you the reference pack, I’d like an initial progress screenshot to confirm the main dimensions before you refine the blades and add fillets. Final hand-off is the completed, fully constrained SLDPRT with history tree intact.
