Figure 42 Plane created in wall
Note: To best approximate the plane of a large surface, like a wall, you will want
to select regions from a couple of different regions. This will account for any
minor variations in different parts of the wall.
Create Plane from Points
You can also create a plane by selecting 3 or more points in range or model data. Begin by
selecting
Create Plane from Points
in the Draw & Measure menu, or the corresponding button
(
) from the toolbar. Then, holding
Ctrl
, select at least 3 points in the same plane and double-
click on the last point. A plane will be created fit to the points you selected.
Moving and Resizing a Plane
Once created, a plane can be resized by selecting and dragging its endpoints in the same way
landmark points and lines were moved. There are also two functions in the Measuring Toolbar
for resizing planes. Click on
Fit Plane to Model Bounds
(
) to make the plane large, or on
Reduce Visible Plane Size
(
) to make it smaller. You can select the latter button multiple
times to reduce the plane size further. Even though the plane is small, it is defined to extend
throughout the model space.
If you select the arrow button, and drag with
Ctrl
, the plane snaps to data or other annotations.
The plane's orientation doesn't change, but it's position does.
If, however, you use
Ctrl
-
Alt
and then drag any point of the plane you can move it to new
locations along the axis perpendicular to the plane. In this way you create a new plane that is
parallel to the original plane. This is a particularly useful for deleting unwanted data beyond a
plane. This is discussed in section 12.4.
Note: Once you move a plane in this manner, it is no longer the same plane you
created. If you would like to keep the original plane and also make a plane
parallel to the original, use the
Duplicate Plane
function in the Draw & Measure
menu or the corresponding button (
) in the toolbar. You can then move one of
the planes without moving the other.
Move Plane Along Normal
You can move a plane along its normal (the axis perpendicular to the plane) by a specific
distance. Select
Move Plane Along Normal
from the Draw & Measure menu. A window will
