Construct Surface dialog box
There are two types of constructed surfaces (Independent Surface and Dependent Surface) available in PC-DMIS. The following table shows the two surfaces, along with their necessary inputs. The only input that the surface will take is a patch scan. The scan must contain at least two rows of four points per row.
