7.1) Introduction
Copyright ©2009 by K. PlantenbergRestricted use only
Introduction Cutting planes lines are created
manually using the Phantom line type. → They are very thick and placed on their own
layer. Section lines (or Hatches) are created
automatically once a cut region has been selected.

Cutting Plane Lines Creating a cutting plane line.
→ A line is drawn indicating where the part is to be cut.
→ MULTILEADERS are used to indicate the view direction. The arrow size is usually larger than a dimension line arrowhead.

7.3) Hatches
Copyright ©2009 by K. PlantenbergRestricted use only
Hatches Section lines are
created using HATCHES. → AutoCAD has
many predefined hatches.

Hatches The most commonly used hatches are:
→ ANSI31 = Cast Iron or general use→ ANSI32 = Steel→ ANSI33 = Brass, Bronze, Copper

Hatches The angle and scale at which the hatches
are drawn may be controlled within the Hatch and Gradient window.
0o represents the default angle of the hatch. Usually 45o.

Hatches Boundaries
→ Add: Select objects: This method allows you to select the objects that will create the boundaries of your sectioned area.
