Accepted Answer

A)  isometric baselines 
B)  relative baselines 
C)  reference baselines 
D)  vertical baselines 
A)  isometric baselines 
B)  relative baselines 
C)  reference baselines

Question 2

List the steps in making a simple isometric sketch.

Accepted Answer

STEP 1 Sketch the three isometric axes. If a ruled isometric sheet is available, select three lines for the major axes. 
STEP 2 Lay off the 3" length along the right axis, the 20 depth on the left axis line, and the 10 height on the vertical axis line. 
STEP 3 Draw lines from these layout points parallel to the three axes. Note that all parallel lines on the object are parallel on the sketch. 
STEP 4 Dimension the sketch. On isometric sketches, the dimensions are placed parallel to the edges.

Accepted Answer

A)  the front face 
B)  one corner 
C)  the back face 
D)  its top 
A)  the front face 
B)  one corner 
C)  the back face 
D)  its top B
