List the steps in sketching an irregularly shaped part.
What will be an ideal response?
STEP 1 Lay out the two basic rectangles required for the shaft support. Use light lines and draw the outline to the desired overall sketch size.
STEP 2 Place a dot at the center of the top horizontal line and draw the vertical center line. Also, draw two vertical lines for the sides of the top rectangle.
STEP 3 Locate dots and draw horizontal lines from the left vertical line to locate:
A. The rectangle for the top of the support
B. The center line of the hole
STEP 4 Draw the squares for the rounded corners of the base, top, and the center hole. In these squares:
A. Draw the diagonals and form the triangles.
B. Locate dots in the centers of the triangles through which each arc will pass.
STEP 5 Draw the arcs and circle. Start at one diagonal and draw the arc through the dot to the next diagonal. Continue until the circle is completed.
STEP 6 Draw the side view if necessary.
STEP 7 Darken all object lines and dimension. Erase those lines used in construction that either do not simplify the sketch or are not required to interpret the sketch quickly and accurately.
