Chapter 7 sectioning in auto cad 2010
Download as PPTX, PDF1 like427 views
This document discusses how to create section views in AutoCAD. Chapter 7 covers cutting plane lines, which are thick phantom lines that indicate where an object will be cut. Leaders are used to show the direction of the view. Section lines, also called hatches, are automatically generated once a cut region is selected. Common hatch patterns include ANSI31 for cast iron and ANSI32 for steel. Hatches can be customized by adjusting the angle and scale in the Hatch and Gradient window. Boundaries for cut regions can be added by selecting objects or picking points.

- 6. Copyright ©2009 by K. Plantenberg Restricted 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.

- 8. Copyright ©2009 by K. Plantenberg Restricted use only 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.

- 10. Copyright ©2009 by K. Plantenberg Restricted use only Hatches Section lines are created using HATCHES. → AutoCAD has many predefined hatches.
- 11. Copyright ©2009 by K. Plantenberg Restricted use only Hatches The most commonly used hatches are: → ANSI31 = Cast Iron or general use → ANSI32 = Steel → ANSI33 = Brass, Bronze, Copper
- 12. Copyright ©2009 by K. Plantenberg Restricted use only Hatches The angle and scale at which the hatches are drawn may be controlled within the Hatch and Gradient window.
- 13. 0o represents the default angle of the hatch. Usually 45o.
