#### Find Nearest CAD Element

The Find Nearest CAD Element icon tells PC-DMIS to find the nearest CAD element in the Graphics Display window based on the XYZ location and any selected axis (or axes). PC-DMIS allows you to either type or surface-select the pertinent information.

Understanding Axes Check Box Selecting

- For Vector Points or Surface Points - If you select an X, Y, or Z axis check box, PC-DMIS interprets the selection as the axis that will be modified when you click the Find Nearest CAD Element icon.

- For Edge Points or Angle Points - If you select an X, Y, or Z axis check box, PC-DMIS interprets the selection of the axis as a selection of the one axis that will NOT be modified when you click the Find Nearest CAD Element icon. For example, if you select the X check box, PC-DMIS will actually check mark the Y and Z check boxes signifying that the Y axis and Z axis values will be modified by the Find process.

Understanding the Find Operation without Selecting Axes Check Boxes

- For Edge Points and Angle Points - If you click the Find Nearest CAD Element icon without an axis selection, PC-DMIS will find the closest CAD edge or angle point.

- For Vector Points and Surface Points - If you click the Find Nearest CAD Element icon without an axis selection, PC-DMIS will find the closest CAD along the Normal vector specified in the dialog box. PC-DMIS will then populate the dialog box with the found vector.
