The Fit Geometry Tool allows you to fit geometry based on edges. Click on the Fit Geometry Tool and
then pick a point on your image. Pick another point and the
system will fit the geometry between the points (this could be a line or circle). As you continue
to pick points, it will best fit the geometry related to those points.
A right click revokes this tool.
The Edge Snap assists the user in finding edges.
epending on how the parameters are set, the snap tool will "snap" or find the nearest edge to where the user dropped and clicked the point.
To set the type of geometry the system will fit, right-click on the Fit
>button to bring up the following menu:
Auto will automatically fit the best geometry, based on the points you select.
Line will fit the best line, based on the points you select.
Circle will fit the best circle, based on the points select.
Edit allow you to make adjustments for your selections to snap to the nearest edge, change sensitivity and polarity. (See help on this page)
How to Determine Diameters
Click the Fit button.
Select a minimum of three points around the diameter of the circular area. In the example below, the software draws a circle for the inside diameter of a washer.
If you wish, you can take a calibrated measurement of the diameter. Click the Distance
(between geometries) button; the cursor changes to a hand symbol.
Click anywhere on the selected diameter; the diameter is calculated and displayed as in the example below:
