Creating Section Views in AutoCAD

Summary


Summary What will we learn in Chapter 7?

→ How to create a cutting plane line and a section view.

Key points→ Hatches = Section lines



7.1) Introduction


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.



7.2) Cutting Plane Lines


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


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.

Hatches Boundaries

→ Add: Pick points: This method allows you to pick a point within each bounded area that you wish to place hatches.
