Revolved
Removed
Offset

Normal View contains the Cutting Plane Line
Note – Hidden Lines become solid Object Lines on the Section View

11. Creating a Full Section View Drawing
Open your PHS “A” size border & title block.
Create the base view for the part file titled, “Bracket Full Section.”
Select the Top View Orientation

Right-click and pick Continue.

13. Creating a Full Section View Drawing
Move the cursor below the base view and pick a point to establish the section view.
Notice that the cutting-plane line, section lines, and identifiers appear automatically.

14. Section View Line Types
Cutting Plane Line – placed on the normal view to show on the normal view where the cutting plane passes through the object.
Section Lining or Crosshatching – evenly spaced lines placed on the section view that show where material touched the cutting plane.
Typically drawn at a 45⁰ angle.
