The Import, Sources command allows you to import PCD format files which should include XYZ point data and can also include
a target spacing and decay for each point. Files can be ASCII, binary and binary compressed with formatting determined automatically. If
spacing and decay are not included, they can be specified manually after import. However, in this case, the source type will automatically
be set to constant. If default values for Spacing and Decay have been set in the
Defaults panel, they will be applied. See Grid, Sources for more information.
After selecting File, Import, Sources, a file browser will be presented prompting you to navigate to the folder containing your PCD file.
