Use Edge Points On-the-Fly to manually inspect the boundary of a surface. To measure an edge point you must take a point on the surface near the edge you want to inspect, followed by a point against the edge.
To probe edge points on the fly:
A yellow triangle is displayed on the part in the CAD view to indicate where you must probe the edge of the surface. The coordinates of the point are displayed on the left of the Edge Points On-the-fly dialog.
The colour of the dL value and the triangle displayed in the CAD view indicate whether the point is within tolerance (green), below tolerance (blue), or above tolerance (yellow).
To view the details of a measurement, select a point in the inspection group, and then select the Info tab.
