Butterfly Valve Assembly of Geometric Dimensions And Tolerances Using Software NX CAD.
GD&T Is a mean of dimensions and tolerancing drawing which consideres the function of the part and how this part function is related to the other part.
This allows a drawing to contain a more defined feature and more accurately without incresing the tolerances.
How the development of GD&T will process in industry.
Firstly we have to manufactured the product component.

Assembly of the part model.
The Significances of GD&T Is as follows.
- It controls the dimensional variation in parts, less variation, less waste can be maintained.
- It performs the gap analysis of the part.
- Root square system is used in the GD&T by using this we can save a lot of money.
- It reduces the elimination inspection of some features.
- GD&T is a universal language for the symbols.
- Which provides the bonus tolerances to the symbols.There are 14 types of GD&T symbols will use it here
- 1) FLATNESS
- 2) STRAIGHTNESS
- 3) ROUNDNESS
- 4) CYLINDRICITY
- 5) PROFILE OF A LINE
- 6) PARALLELISM
- 7) PERPENDICULARITY
- 8) ANGULARITY
- 9) TRUE POSITION OR POSITION TOLERANCE
- 10) CO AXIALITY
- 11) SYMMERTYCITY
- 12) CIRCULAR RUN OUT
- 13) TOTAL RUN OUT
The butterfly valve assembly can be made with the proper dimensioning method followed by the given instructions and part is created.
Each and every part is crearted by the proper dimensioning method.

The final part of the butterfly valve assembly part is inserted below by joining all the parts together and connected with unite option from the NX CAD.
By the proper dimensioning method of GD&T We created the final assembly part of the butterfly valve and it is inserted below.
The drawing of the butterfly valve assmbly is mentioned below.

The image of the butterfly valve assembly is shown below with the proper final assembly part.
