In-Depth Information
The relationship between paper space and model space is quite interesting.
Viewports allow you to peer into model space from your layouts. The end result
is a drawing sheet that, when plotted, displays everything drawn in paper space
in addition to model space objects drawn inside the viewport boundary. To help
you experience how this relationship works, try the following:
1.
Place your cursor over an object inside the cabin, click just once and
then move the cursor.
Rather than selecting the object, you began a selection window. Drag
the window around some of the objects near the cabin and then click
again. Nothing is selected.
2.
Move the cursor over both the white and gray areas of the drawing
window and notice how the crosshairs appear over both.
This informs you that you are currently working in paper space and
can select only paper space objects such as the viewport (once you move
them into paper space in the next section), the title block, and border.
To work on the cabin itself, you need to change to model space. You can
do this in two ways. One is to click the Model button. This temporarily
removes the layout and leaves you with just the drawing, or model. The
other way is to switch to model space while a layout is active.
3.
Place your cursor within the viewport area and this time double-click.
The viewport border becomes bolder and, when you move the cur-
sor beyond the viewport, the cursor changes from a crosshair to an
arrow. You are now in model space and are able to select the model
space objects, but not any objects that reside in paper space.
When you activate
model space while a
layout is active, it is
like opening a win-
dow and reaching
through the opening
to touch the draw-
ing of the building
behind the window.
4.
Double-click the cursor outside of the viewport. The crosshair cursor
returns, and you are back in paper space.
TIP
You can also click the MODeL button in the middle of the status
bar to move from model space to paper space. When you are in paper space,
this button changes to paper, and it will toggle you back to the current
model space viewport.
