Dimensions Note

What are Dimensions: The purpose of dimensions is to show the size and location for the features shown.

Why Use Dimensions: To ensure that the part made is the part you asked for.

Extension lines extend from to dimensions

Leaders cannot be vetical or horizontal lines, may be mistanken as the object.

Conversions:
Metric:
1" = 2.54cm
1" = 25.4mm

Imperial:
1' = 12"

196 cm = 6' 5"
1km = 1000m = 10000 dm = 100000cm = 1.0 x 10^5cm

Two Methods: Alligned and unidirectional.

-Do not place dimensions on the object
-Do not dimension to hidden lines
-Leaders should not be drawn at horizontal or vertical angles
- Complete circles are dimensions with diameters

These rooms include the kitchen, washroom and laundry room (Containing the electrical boxes and piping). This allows for more organized plumbing and electrical systems. The rest of the rooms contain reletively no uses for plumbing, such as the living rooms. Only other access to Hydro utilities is the Main bedroom which has an attached Ensuite.

value or physical property of a material

Allowance: a planned deviation between an actual dimension and a nominal or theoretical dimension. An engineer can alter the sizes of dimensionson paper.
Theoretical and Nominal: On paper

Geometric Tolerancing: Symbolic language used in engineering drawings, and computer generated 3D solid models for explicity
