Dimensioning

• Dimension with intent to manufacture
• All dimensions from one setup coming from the
  same datum
• Parts with many dimensions may need two or more
  different drawings

Views

• All drawings must have an isometric view with
  hidden lines shown
• Only show enough orthogonal views required to
  make the part
• Orthogonal views must have hidden lines shown

Dimensioning Tools

• If hole wizard is used to create hole(s),
  SolidWorks has a hole callout tool that will call
  out the hole correctly
• SolidWorks is also capable of creating section
  and broken views

14
Tap drills vs. Body drills

• Tap drills are used to make holes that will be
  tapped
• Body drills are used to create through holes

15
Sketching

• Attempting to sketch in SolidWorks often presents
  more obstacles than just using pencil and paper
• Jumping into SolidWorks before your design
  intensions are clear causes problems. i.e.
  origins, planes, ect
