Drawings of Parts with Rotational Geometry

Drawings of Parts with Rotational Geometry

Drawings of Parts with Rotational Geometry

(OP)
Does anyone have any good practices for making 2-D drawings of parts with rotational geometry?  Below is an example of an impeller I am working on.  I would like to "automatically" create a 2-D side drawing similar to the last one, which I manually created.

I am interested in hearing your practices for how you handle parts like this.  The side views and section views that are automatically created are too cluttered an aren't much use to the machinist.  I would also appreciate any references you can offer on this topic (either internet sources or books).




RE: Drawings of Parts with Rotational Geometry

Create a simplified config, and insert that particular config into your drawing.

RE: Drawings of Parts with Rotational Geometry

I would create a section view through the center of the part, cutting through the veins. You may need other views showing different variables of the veins.

RE: Drawings of Parts with Rotational Geometry

I agree with Chris.  The section views shown in the image aren't very useful.  Create two section views.  One that cuts thru the middle of the part (as described by Chris) so the veins can be dimensioned as a pattern, and a second section that cuts thru the part in a way that goes alone the part symmetry thru the center (similar but not the same as to what is on the image) to allow dim'ing of the conical features.  

You may also wish to do a detail of the first section that focuses on the directors for close up dimensioning.  Just some ideas.  Good luck!
