To Create a Normal Plane
By using the Normal option, you can create a Constructed Plane through a point and normal to a line or axis.
1. Click > 
Plane. The CMM Construct tab opens.
Plane. The CMM Construct tab opens.2. Select the parent reference Csys from the Parent Csys drop-down list.
3. Select Normal from the Type drop-down list.
4. Select two measure or construct steps in the following order:
a. First, specify a reference point. Select a measure or construct step of the following types:
▪ Point
▪ Circle (center)
▪ Cone (cone vertex)
▪ Sphere (center)
The new constructed plane passes through the selected step.
b. Next, specify a line. Select a measure or construct step of the following types:
▪ Line
▪ Cylinder (axis)
▪ Cone (cone axis)
The new constructed plane is normal to the selected step.
5. Click OK.
