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 round slot:
Open the Construct Round Slot dialog box (Insert | Feature | Constructed | Round Slot).
From the Method list, select the method of the constructed round slot. The available options are:
Circles
Best Fit
BF Recomp
Projection
Cast
Extracted Round Slot
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:
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
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.
Click the Create button to create the Constructed feature based on the final features and feature components that you selected.
Constructed feature created based on selected items from the Feature list
Using the table above, select the features from the Feature list based on the selected method.
Select the In or Out option. For details, see the "In / Out Slot" topic in this documentation.
If you chose one of the best fit methods, select either the 2D or 3D option. For details, see the "2D / 3D Slot" topic in this documentation.
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.
Click the Create button.
The Edit window command line for a sample Slot Construction would read:
feature_name=FEAT/SLOT,TOG1,TOG2,TOG3
THEO/x_cord,y_cord,z_cord,i_vec,j_vec,k_vec,width,length
ACTL/x_cord,y_cord,z_cord,i_vec,j_vec,k_vec,width,length
CONSTR/TOG4,TOG5,TOG6,TOG7,feat_1,feat_2, …
The actual report displays in all capital letters.
TOG1 = CARTESIAN or POLAR
TOG2 = OUT or IN
TOG3 = YES or NO
TOG4 = SLOT (or other construction type)
TOG5 = ROUND or SQUARE
TOG6 = CIRCLES or BF or BFRE or PROJ
TOG7 = 2D or 3D (This appears only if TOG6 reads BF or BFRE)
