FORD D-6-2007 EDGES OF WORKPIECES (Version 28).pdf

1、 FECDS D-6 Engineering CAD _ individual indications for all edges around the represented profile of a part; _ collective indications common to all or the majority of a parts edges. Individual indications are immediately assigned to a line (e.g. visible outlines, areas with specific treatment or exte

2、nsion lines), or to a point representing an edge parallel with, or vertical to, the projection plane (see Figures 14to 16). Collective indications are indicated only once for all the common edges and are located near the representation of the part or near the title block (see Figures 17 to 21). 4.6.

3、4 When the requirement for the state of an edge is common to all the edges of a part, one collective indication at the appropriate position on the drawing (near the representation or the title block, as in Figure 17) will suffice. Collective indications of states common to only external or internal

4、edges shall be indicated in accordance with Figure 18 and Figure 19, respectively. Return to TOC ENGINEERING CAD & DRAFTING STANDARDS Original Issue: 19960419 Copyright, Ford Motor Company.

6、right of the collective indication see Figure 20 a) and b) . For purposes of simplification, if more than one other state of edge is present, only the basic symbol shall appear in parentheses at right of the collective indication (see Figure 21). 4.7 Reference to this International Standard It is recommended that reference be made to this International Standard either within or near the title block, and in the manner shown by Figure 22. 2 DEFINITIONS (Reserved) 3 REQUIREMENTS (Reserved) 4 SPECIFICATIONS (Reserved) 5 ADDENDUM (Reserved)
