#### IJK Angle boxes

For Circle, Cylinder, Sphere, and Cone features, the Angle boxes define the 0° position about the normal vector. The start and end angles are calculated relative to this vector. If the vectors are not perpendicular, the angle vector is adjusted to the normal vector.

For Square Slot, Round Slot, and Ellipse features, the Angle boxes define the feature's secondary vector. This is a user supplied I, J, K normal vector. The feature centerline and normal vector must be perpendicular to each other.

For a Notch feature, the Angle boxes define the notch's secondary vector orientation. This is a user supplied I, J, K normal vector along the back side of the slot. The notch angle vector and notch normal vector must be perpendicular to each other.

For a Plane feature, the Angle boxes define the plane's secondary vector. This helps control the orientation of the plane's path.

To change the Angle Vector:

1. Select the boxes you want to update.

2. Type a new value.

After a new value is created, PC-DMIS will normalize the vector, making it a length of 1.
