You can create and edit a perspective grid with this tool. Click the &LMB; and
|
|
drag the mouse to indicate the first two corners of the grid, then click for
|
|
the third and fourth corners. The outline of the grid is now shown and you can
|
|
edit it if you are not completely happy. When you switch to a different tool,
|
|
the perspective grid will be subdivided and shown as thin gray lines.
|
|
</para>
|
|
<note><para>If you only see three corners instead of four, you probably
|
|
clicked instead of dragging initially. In this case you can still click the
|

handle of your now combined first and second corners and drag it to get four
|
|
separate corners.</para></note>

Clicking the <guilabel>Perspective Grid</guilabel> tool again later will allow

you to modify the grid. You can hide or remove the grid by choosing the

<guimenuitem>Hide Perspective Grid</guimenuitem> or <guimenuitem>Clear
|
|
Perspective Grid</guimenuitem> options from the <guimenu>View</guimenu> menu.
