Constructing a Round Slot Feature

Construct Slot dialog box

There are two round slot types in PC-DMIS: a round slot created from two circles (Circles option) and a round slot created from four or more inputs (Best Fit or BF Recomp option). The table below shows the inputs for the slot and the editor definitions.

Constructs a round 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 round slot:

  1. Access the Construct Round Slot dialog box (Insert | Feature | Constructed | Round Slot).

  2. Select the In or Out option to define the constructed slot as a hole or stud slot respectively.

  3. Select one of the following construction methods: Circles, Best Fit, BF Recomp, Projection or Cast.

  4. Select your inputs based on the type of slot you will construct.

  5. If you select one of the best fit options, choose to construct either a 2D or 3D feature.

  6. 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)
