Drawing Subassemblies
Subassemblies are similar to template surfaces and are drawn in the same
manner as template surfaces. Due to the nature of how you apply
subassemblies, you must follow a few different rules when drawing
subassemblies:
n
Unlike templates, subassemblies can be either open or closed surfaces.
n
Like templates, subassemblies are drawn as polylines and the process of
creating the polyline is exactly the same for both. For more information, see
the section Drawing Templates in Chapter 5, Working with Cross
Sections.
n
You must draw subassemblies for the left side of the template only. When
you attach a subassembly to a template, it is automatically mirrored to reflect
the correct orientation for that side of the template. If you are going to
attach a subassembly to the right side of the template only, then you still
need to draw and define it as if it is being attached to the left side.
n
When you attach subassemblies, you can use different subassemblies on the
left- and right-side of the template.
The following illustration shows examples of how you might draw shoulder and
curb subassemblies:
