There are also other ways to dimension the part.
Placing Ordinate Dimensions and
Automated Centerlines
Ordinate dimensions (like baseline dimensions) can be placed either as individu-
als or as a set. The Ordinate Set option keeps the members styled as a set and
also automatically does some spacing of the dimensions.
1. Verify that the 2013 Essentials project file is active, and then open
c06-17.idw from the Drawings\Chapter​6 folder.
2. Right-click within the boundary of the view, and select Automated
Centerlines from the context menu.
The Automated Centerlines dialog box (Figure 6.25) allows you to
select whether to include cylindrical extrusions or faces that have
a radius, and you can also choose whether to select objects with an
axis that is normal or parallel to the view.

center mark of the large hole in the lower-right corner of the part.
