Week 14 challenge
Aim : To Assemble and apply GD&T to the butterfly valve assembly drawing.
Given Data : Use previous drawn models and assemble.
Tool : Nx-12.
Procedure :
- Make sure of all parts should place in single folder.
- Open Nx cad and Create new assembly file.
- Assembly workbench opens.
- By clicking on add components, add all the parts whatever required.
- Place all parts with some distance between them to see all sides properly.







- After adding all parts fine tune it with using constraints option.
- It helps to locate and place the parts with one another properly.
- Here Assembly constraints of Center axis, Touch align, Align options are used to assemble whole butterfly valve assemmbly

Assembly :




- Hence assembling of all parts in a assembly work bench is completed
- Now drafting should be done.
- Use drafting option in application feature to activate the drafting workbench.
- Select required paper size.
- Create a base view and place.
- Create a projected side view from base view.
- Now dimension the required dimensions and Use GD&T symbols to contraint the drawing.

- Primary datum A is given to a surface with some diameter area at three places instead of giving to whole surface and provided some flatness tolerance.
- It contraints the 3degrees of freedom.
- The secondary datum B is provided to feature of size of a hole with some position tolerance with respect to Datum A.
- It contraints the 2degrees of freedom.
- My tertiary datum C is also provided to feature of size of a hole with some perpendicularity tolerance with respect to Datum A and B.
- It contraints the 1degree of freedom.
- Here Datum D also provided with some position tolerance with respect to datum A,B,&C.
- The other side of body the holes are constrained with concentricity tolerance with respect to their opposite datums.
- The other side of body the surface is constrained with Profile of surface with respect to Datum A,B,C.
- Hence drafting & applying GD&T symbols are done.
Conclusion :
- Assembling of all parts in assembly worjkbecnh is done.
- Drafting to assembly drawing is done.
- Dimensioning is also done.
- Applying GD&T symbols to drawing is aslo done.
