The RunChangeComponentsMap sheet provides options for mapping PDMS piping run change components, such as reducers and tees, into Smart 3D. Use this mapping sheet to map the PDMS SPRE to the NPD values for each PDMS component port in ascending order. For example, map the NPD value (NPD1) for Port1, and then map the NPD value (NPD2) for Port2, and so forth.
