The only standard across engineering workshop drawings is in the creation of orthographic projections and cross-section views. In representing complex, three-dimensional objects in two-dimensional drawings, the objects can be described by at least one view plus material thickness note, 2, 3 or as many views and sections that are required to ...
Sectional views: The plane upon which a sectional view is taken should be indicated on the view from which the section is cut by a broken line. Alternate position: A moved position may be shown by a broken line superimposed upon a suitable view if this can be done without crowding; otherwise, a separate view must be used for this purpose, and
In addition to the six principal views (front, back, top, bottom, right side, left side), any auxiliary views or sections may be included as serve the purposes of part definition and its communication. View lines or section lines (lines with arrows marked "A-A", "B-B", etc.) define the direction and location of viewing or sectioning.
This cutaway view originates in the early fifteenth century notebooks of Marino Taccola (1382 – 1453). In the 16th century cutaway views in definite form were used in Georgius Agricola 's (1494–1555) mining book De Re Metallica to illustrate underground operations. [ 4 ]
Another way isometric projection can be visualized is by considering a view within a cubical room starting in an upper corner and looking towards the opposite, lower corner. The x -axis extends diagonally down and right, the y -axis extends diagonally down and left, and the z -axis is straight up.
