Generating Elevations - AutoCAD 2011 and AutoCAD LT 2011: No Experience Required - page 546

2. Drop construction lines from the floor plan across the drawing area
and height lines, which you'll draw from the copied elevation.
3. Trim or fillet these lines as required, and add any necessary lines.
Draw the roof first and remember that there is a thin layer of
roof covering (see the top of Figure 10.49).
Draw the wall, door, and foundation next. You won't be able
to get the height line for the sliding-glass door from the side
elevation. It's 7 ′ -3 ″ (2210 mm) from the top of the deck (see the
middle of Figure 10.49).
Finally, draw the pop-out, deck, railings and support posts. The
railing posts have the same size and spacing on the front of the
deck as they do on the sides, and the support post measures 1 ′ -0 ″
(305 mm) across. This can create a congested drawing, and you
may want to draw the guide lines only as necessary to draw each
component and then erase them. (See the bottom of Figure 10.49.)
TIP although colors aren't visible in this topic's grayscale print, it's
a good idea to “layer” your drawing as you go when working with so many
extension lines at once. Since each layer has a different color, assigning lay-
ers as you go will help you differentiate between objects by color.
4. Erase or trim away any lines that represent objects that are visually
behind any objects in the foreground.
For instance, do not draw two lines on top of one another in areas
where the foundation is behind the steps or support posts or the ver-
tical door lines that are behind the railings. Only draw the features
you would see if you were standing at the front of your cabin.
5. Make sure all the objects reside on the proper A-ELEV-… layer.
6. When you're done, the east elevation should look like Figure 10.50.
7. Erase the copy of the south elevation and the diagonal transfer line.
8. Name and save the UCS and view (call them both East_elev).
