DESIGN DEVELOPMENT: JOINERY
FIGURE 4-17
Bench with reference
lines overlayed onto the
seat
DRAW SEAT REFERENCE LINES
14A: Sketch two reference lines along the top
of the beam. Sketch a third parallel line and
center it between them. This is your centerline.
14E: Draw a line along the top end of the seat
and move each 4″ toward the center of the
bench. Then repeat this step at the other end.
14B: Make two copies of this centerline, mov-
ing the first 2″ toward the front of the seat and
the other 2″ toward the back.
14C: Sketch a line perpendicular to the beam,
connecting front and back midpoints of the
seat. This is the centerline in the short direc-
tion.
14D: Make two copies of this line, moving the
first 2″ toward the left end of the seat and the
other 2″ toward the right end.
14F: Your bench should now look like
Figure 4-17.
By snapping to midpoints and endpoints of
your model, you can quickly draw reference
lines. Use the measuring tool to confirm the
distance between guidelines and parts of the
model.
