You're almost ready to insert the A-ROOM-INFO block in each of the three rooms
and the decks. But first you need to calculate the area of each room.
Calculating Areas
You can calculate areas in a drawing by using the
HATCH
command in conjunc-
tion with the Properties palette or by using the Area tool. Because area calcula-
tions are made over and over again in design, construction, and manufacturing,
the
AREA
and
MEASUREGEOM
commands are important tools. You can calculate
an overall area and then subtract subareas from it, or you can add subareas
together to make a total. Chapter 11, “Working with Hatches, Gradients, and
Tool Palettes,” covers hatches.
For this exercise, you'll use the Area tool to calculate the areas of the five floor
spaces in the floor plan. You need to write down the areas after you make the
calculations. Follow these steps:
1.
Create a new layer named A-AREA-NPLT, and make it the current layer.
2.
Freeze all the other layers except A-DECK, A-GLAZ, and A-WALL.
Your drawing should look like Figure 9.20.
the lines you'll draw
on the a-area-NpLt
layer will be used for
reference and not
plotted in your final
plans. this is why
we're using the NCS
code NpLt, which
stands for No plot.
FiGuRE 9.20
The floor plan with all layers turned off except A-AREA-NPLT,
A-DECK, A-WALL, and A-GLAZ
TIP
When you want to select all the layers in a drawing except a
few, select those few layers in the Layer properties Manager, right-click,
and choose Invert Selection from the context menu. the unselected layers
become selected and the selected layers are deselected.
3.
Make sure that the Endpoint osnap is running.
