6.1 Placement and Orientation of Views
The standard arrangement of orthographic views or alternate positions may be used to conserve space. Orthographic views, unless removed as described below, shall be properly oriented to one another based an orthographic praection and whether first- or third-angIe projection is use& For example, right- or left-side view might be placed adjacent to and in alignment with the top view. The rear view is sometimes placed in alignment with and to the right of the right-side view. The coordinate system may be used to indicate view orientation, and to establish the relationships between views, When complex features need to be related in the drawing, and pictorial views are inadequate, orthographic views, saved views in the model, or a design model shall be used.
6.2 Removed Orthographic Views
Under certain conditions, it may be impractical to place an orthographic view in its normal aligned position in a drawing graphic sheet. In this instance, viewing indicators are used to indicate from where the view was taken, and the view is removed to another location on the field of the drawing graphic sheet. See Fig. 6-I. Removed views are preferably shown on the same sheet from where the view is taken. The removed view is identified using the view letten4 The removed view may be drawn at the same scale as the view from which it is taken, or it may be drawn at a noted scale. It is also permissible to use a combination of numbers and letters for removed view identification as explained in paras. 6.3 and 6.3.1.
When the views are generated From a model or design model based on ASME 114.41 and there are exceptions in that standard to the principles addressed in this Standard, requirements from ASME Y14.41 take precedence. Among the requirements in ASME Y14.41 is the specification that a coordinate system may be used to indicate view orientation for orthographic views.
6.3 Identifying Removed Orthographic Views
To relate the viewing plane or cutting plane to its removed orthographic view, uppercase letters such as A, B, C, etc., are placed near each arrowhead, The corresponding removed views are identilied as VIEW A-A, VIEW li-K. VIEW C-C, etc.
