Design of Butterfly Valve Assembly using GD&T on NX-11 CAD.

Designed and drafted complete assembly of Butterfly Valve using GD&T standard ASME Y14.5-2009 on NX- 11 Software.

1. Designed all components of Butterfly Valve such as Body, Shaft, Disc plate, Lever, Nut, Screws and Retainer Plate using Sketch, Revolve & Extrude command in Part Module of NX.

2. Assembled all parts of Butterfly Valve using assembly constraints such as Touch, Align, Infer Center/Axis and Parallel constraint in Assembly Module and performed Clearance Analysis check to avoid interference.

3. Applied Datum Targets and Datum Feature Symbols to constraint the parts in Drafting Module.

4. Applied Maximum & Least Material Conditions to the feature of size in Feature Control Frame.

5. Applied Maximum Material Boundary Conditions to the datums for loose fit between holes and Pins.

6. Provided Size & Geometric tolerances such as Position, Composite Position, Profile of a surface, Flatness and Perpendicularity tolerance to every feature of size in drawings.
