For Best Fit (BF) or Best Fit Recompensate (BFRE) constructions, while you can use any feature type for your input features, BF and BFRE fit types are typically used with point features or point sets (a scan of points, a feature set with points, or an expression that resolves to an array of points).

If you select inappropriate feature types, PC-DMIS displays this message on the Status bar:

"Cannot construct [feature]. Combination of input features not accepted."

To construct a square slot:

  1. Open the Construct Square Slot dialog box (Insert | Feature | Constructed | Square Slot).

  2. From the Method list, select the method of the constructed ellipse. The available options are:

  3. If you select the Best Fit or the BF Recomp (Best Fit Recomp) method for this feature, PC-DMIS allows you to click the Select All Hits button to create the construction from the individual hits of the input features instead of their centroids.

    To do this:

    1. From the Feature list, select the feature or features that you want to use to create the constructed feature.

    Example showing a selected feature prior to clicking the Select All Hits button

    1. Click the Select All Hits button to display all the components that comprise the selected feature or features.

    Display of items that make up the selected feature are highlighted in the dialog box and in the Graphic Display window

    PC-DMIS displays and highlights all the components of the selected feature (or features) in the Feature list of the dialog box. You can select or de-select any of the features or feature components shown in the list to include or exclude them.

    1. Click the Create button to create the Constructed feature based on the final features and feature components that you selected.

  5. Remember, the order you select the features from the list determines the orientation (CW or CCW) of the Constructed Square Slot. See the examples below.

  8. If you want to change the feature theoretical values, select the Feature theoreticals check box and type in the values. For details, see the "Specifying Feature Theoreticals" topic in the PC-DMIS Core documentation.

  9. Click the Create button.
