Assignment 6
Auxiliary Views
This image is a template for the following problem
Ex 7-1A
^
Below is the side view that replaces the 40x40 square above |
Draw the whole layout, using the given front view, the side view below, and the aux view to match the
side and front views.
7-5 Angle of front face is not Known, but once you draw the side view you can determine the angle using
the dist command. See p273 AND Fig 7-9 on p274. Draw front, side, and auxiliary above front. No top
view needed
7-17. Dimension errors: 45 degree cut. Substitute 17.32 for 17, 42.43 for 52.
Start by drawing a regular orthographic ( Front, top, side) view.
For top view, draw a circle of radius 30 and a hexagon outside it that touches the circle at the midpoint
of the sides. Make sure you rotate it so the points are top and bottom (top view).
Draw the front view below, then use the mitre line to project out to the side view. The hole appears as a
circle in the top and side views (because of the 45 degree cut)
Once the orthographic is complete, you can move the top view up out of the way and add an auxiliary
view of the cut surface. Now the hole will be an ellipse, with a hidden 2nd ellipse for the back end.
EXTRA CREDIT 2 points
Ex 17-35 This has an oblique surface. You’ll need to do 2 aux views to get the true shape.
