-------PRE ENGINEERING CONCEPTUAL DESIGN AND PROMOTION SERVICES--------      2D AutoCAD CAN BUILD 3D OBJECTS     The model parts from AutoCAD were generated from the 2D plans and then lofted as shown. One short coming of AutoCAD is in the rendering. As long as the surface is curved one way, such as a lathe process the outcome will be edge to edge with nothing between as shown in the taper of the receptacle and the taper of the Kort nozzle. But, once the shape must have two taper shapes in one, the shape must be defined by triangulation and those lines will show in the rendering. Again, as long as the parts are made of items that can be machined on a typical 3 axis manual mill, good to go. Start making compound shapes and it is time to buy Solidworks or Inventor or similar programs. The link to the side is to a PDF of the model. Here is the same image in JPG.   The images below were generated by importing the 3D model from AutoCAD into 3D max to do a bit of coloring and surfacing. 3D Max will sweep the compound curve, but it will not translate to a smooth transition that will work in any CNC program.     © 1997-2016 c.r. watson - all rights reserved The use of any trademarks, trademarked names, and/or copyrighted information is stated as a fact of record and is not intended to imply endorsement of any kind.
