Give a seven-step procedure for creating a section view.

Question

What will be an ideal response?

Answer 1

When the decision has been made to add section views to a drawing, the next step is to create them. When you are the original designer of the part, this task may be simple since you probably already visualize the internal geometry you want to feature. If the part is someone else's design, the process is trickier because you may need to interpret a rather messy drawing that needs the section views to improve the drawing's presentation. If this is the case, you will need to correctly align, identify, and visualize internal features that have been outlined with hidden lines in adjacent views. This task becomes difficult when some hidden lines are missing or have been removed for clarity. The steps to creating a full section view are outlined below:


Step 1: Identify the feature(s) to be revealed and the desired viewing direction.


Step 2: Draw the cutting plane line that represents the edge of the cutting plane.


Step 3: Outline the modified part in an adjacent orthogonal view.


Step 4: Identify the intersection points of the part's exterior and interior edges with the cutting plane.


Step 5: Outline the internal features associated with the intersection points on the cutting plane.


Step 6: Find the boundaries between solid and empty space and fill the solid areas with section lines.


Step 7: Add or remove background edges in space and remove edges in solid areas.
