Sectional Drawing Test Review

Part Drawings:
-Detail drawings completely describing the part, mostly done orthographically, completely describing a single element. (Specifications)

Assembly Drawing:
-Displays functional relationships between the parts. (Production)

Section View:
-Used to clarify internal detail and to avoid dimensioning to hidden lines.
-They are established by referencing a cutting plane.

Cross-Hatch symbols
-Different materials require (are depicted by) different patterns.

Half Sections
-The result of cutting planes being opositioned on parts in such a manner that only half of the resulting view or projection is shown in section. (Symmetry)

Offset Sections
-Allow us to provide greater breadth of detail with fewer section views. All of the features are alligned with the cutting plane.

Line Types
-Object, Hidden, Center...

Radial Dimensions
-To indicate the size of fillets, rounds, and radii.
