Constructing a Square Slot Feature

Construct Square Slot dialog box

There is a single square slot type in PC-DMIS. Except for the Cast method, a constructed square slot requires five or more input features (Best Fit or BF Recomp option). The table below shows the inputs for the slot and the editor definitions.

Constructs a Square Slot at the centroid of the input feature.

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 "Cannot construct [feature]. Combination of input features not accepted." on the status bar.

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:

  1. Using the table above, select the features from the Feature list based on the selected method.

  2. Select the In or Out option. For details, see the "In / Out Slot" topic in this documentation.

  3. 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.

  4. 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 this documentation.

  5. 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 = BF or BFRE or PROJ

TOG7 = 2D or 3D (This appears only if TOG6 reads BF or BFRE)
