#### Work Plane List

The Work Plane drop-down list allows you to change the plane in which you are working. This will not change the view in the Graphics Display window, only the working plane.

The available work planes are:

A=TOP | Light Gray | ZPLUS
B=RIGHT | Dark Gray | XPLUS
C=BACK | Light Blue | YPLUS
D=BOTTOM | Light Green | ZMINUS
E=LEFT | Red | XMINUS
F=FRONT | Clear | YMINUS

For example, to change the current work plane to the back of the part image:

1. Position the mouse pointer over the down arrow of the Work Plane list.

2. Select YPLUS from the drop down list to get the new working plane.

Measured Lines and Work Planes

When creating a measured line, PC-DMIS expects the hits for the line to be taken at a vector perpendicular to the current work plane.

For example, if your current work plane is ZPLUS (with a vector 0,0,1), and you have a block-like part, the hits for the measured line must be on a vertical wall of that part, such as the front or side.

If you then wanted to measure a line feature on the top surface of the part, you would need to switch the work plane to XPLUS, XMINUS, YPLUS, or YMINUS, depending on the direction of the line.

See the "Measuring a Line" topic for information on creating measured lines.
