Working Drawings Chapter 9

3 major components of working drawings:
1. Drawing that shows how parts are assembled
2.Orthographic views of all the parts
3. Notes for all the standard parts

Assembly Drawings:
First(or last) page in a set of working drawings
Used to show how all the parts fit together.
Pictorial format - isometric, or perspective
Oriented to best show geometry of parts
Route lines - lines connecting components to one another
No hidden lines, centerlines, or dimensions
Part number balloon - circle with number that identifies part
Keep Part numbers consistent through drawing
Table with parts list - corresponding to part numbers.

Typical parts list:
Part number
Part name
Material Used
Required Quantity

Collapsed (parts assembled together)
Exploded (the assembly pulled apart)


Create pg 350, 351, 352




To insert a table, just type "TABLE", then fill in the cells like you would in excel.




For the Balloons with leader lines, type in "TP" for Tool Pallet.
Annotation - tag.
Check out all of the other tools in the tool pallet while you are there!
To rescale the size, or change anything, just select it, right click, and go to the properties box.



Detail Drawings
Orthogonal views
Dimensions for manufacturing
Part name tag
Part number balloon tag


Just use your normal dimensioning tools, then go back and double click on the dim to add more info.

%%c makes the diameter symbol




 Part Notes:

Vendor items
no orthographic views, just need a note with part info
 
Construction notes if needed
Outline how to assemble parts, what types of glues and materials to use, etc.




Create a full set of working drawings for your piston, and for your final semester project.
