I am a Mechanical Engineer specialized in CAD and product design. If you are looking for the CAD drawings and models necessary to print a 3D part or assembly, then this is your choice. With a simple 2D drawing (or sometimes, even with a hand-drawn sketch), I can design your model regardless its complexity or size. Receive your 3D solid part and/or 2D drawing file in any of the following formats: # Parasolid (.x_t) # IGES (.igs) # STEP (.stp) # Stereo Lithography (.stl) # AutoCAD (.dxf) # CGM (.cgm) # Pdf (.pdf) # Others (.jpg, .tiff, etc.)
