For the exercise in this topic, however, you'll create fairly simple frames, door
panels, and glazing.
1.
Make a new layer named A-GLAZ-SILL-3DOB, and set it as the current
layer. Freeze the A-FNDN-3DOB layer, thaw the A-WALL-EXTR-3DOB
layer, and then zoom into the kitchen window near the back door.
2.
Click the Allow/Disallow Dynamic UCS button in the status bar to turn
on Dynamic UCS mode.
When you are in a command, Dynamic UCS causes the current UCS
to adapt to the orientation of whichever face the cursor is over. This is
important because, when using creation tools like the
BOX
command,
the footprint is made in the X and Y plane and the height is projected
along the z-axis. When Dynamic UCS is active, the UCS shown at the
cursor overrides the UCS shown by the UCS icon.
3.
Start the
BOX
command, and then move your cursor near the UCS icon.
Notice that the color-coded axes of the crosshairs match the orienta-
tion and colors (RGB=XYZ) of the UCS icon axes. Next, move the cur-
sor over the faces on the back wall of the cabin and see that the blue
z-axis now points in the same direction as the UCS icon's y-axis. This
identifies the orientation of that particular wall's face.
4.
With the Endpoint osnap active, click the lower-left outside corner of
the kitchen window, and then move the cursor away from that corner.
The box starts to form with its orientation parallel to the outside wall,
and the UCS icon temporarily changes its orientation (see the top of
Figure 16.30). Click the opposite outside corner of the window for the
base of the new box (see the bottom of Figure 16.30).
5.
At the
Specify height or [2Point]>:
prompt, move the cursor
until you can see the box projecting out from the wall and then
enter
-4
↵
(
-100
).
The box's Height parameter projects it 4
″
(100 mm) into the win-
dow opening. You can switch to a Wireframe visual style to see this
more clearly.
6.
Turn off Dynamic UCS, select the box, and move it 1
″
(25 mm) in the
positive X direction to center it in the wall.
7.
The box you just made will be the frame for the kitchen window. Now
you need to make a block-out to subtract from the box to create the
opening for the glazing.
