The interactive Elevation Profile tool generates a graph of height values along a linear path in the view. The profile is calculated using the ground elevation surface in a map (2D) or a scene (3D), and unlike other exploratory analysis tools, the values are derived from the data sources for the elevation surface rather than the view's level of detail.

Now click the OK button to generate the graph. We are interested in two types of profile lines from this data: an "X profile for a given Y value", and a "Y profile for a given X value". The image below illustrates how these two profiles work. The "X profile" data is in the worksheet columns while the "Y profile" data is in the rows.

For many years, a comparator with a part-specific overlay was the only method available for profile inspection of parts such as cutting tools. Shadowgraphs and overlays are still used, but they have largely been superseded.

Graphical record from composite inspection (Figure 5). Figure 5: Graphical record from composite inspection. Profile Inspection. Profile is the shape of the gear tooth curve and is measured from the root to the tip of the gear tooth. The functional, or operating, portion of the profile is the area that is in actual contact during tooth mesh.

Lower Segments of Composite Profile of a Surface. A profile of a surface tolerance with multiple segments is called a "composite profile of a surface". The first (or upper) segment of a composite profile of a surface tolerance is the same as a single segment profile of a surface as described above at the beginning of this topic.

The range of the graph refers to all of the possible y-values. Notice that this graph is similar to the graph in Example #1, except it is upside down. As far as the range is concerned, this graph has an upper limit at 0 and a lower limit at negative infinity since it extends forever and ever in a downward direction, so we can conclude that:
