You can construct a point by changing any given feature into the point. PC-DMIS constructs the point at the centroid of the input feature.
To construct a cast point:
Access the Construct Point dialog box (Insert | Feature | Constructed | Point).
Select the Cast option from the list of options.
Select any feature.
Click the Create button.
The Edit window command line for this option would read:
CONSTR/POINT,CAST,feat_1
