You can import a Compass PLT file directly into Therion, but not a DAT as far as I know. Best regards, Jonny Thanks Jonny, I assume that would be by using similar syntax to that used to import Survex.3d files. However, as I would need to firstly write a project level .dat file in order to include the necessary co-ordinate information before generating the plt file, that makes it no simpler than my 'quick and dirty' fix of importing the original .plt file into Survex and then importing the resultant .3d file into Therion. This also has the advantage of consistent syntax in my Therion file making it easier to see errors. Graham
