Export from Solar Fire
Your charts are already in files Arcus can read. They end in .SFcht and sit in the charts folder Solar Fire saves into, which is the folder you see whenever you open or save a chart file. Copy the file somewhere easy to find and import it.
If your chart files are older ones ending in .Cht, convert them first. Go to Utilities, then Chart Import/Export, and on the Options tab choose to create v6/7 format chart files.
Solar Fire can also write a spreadsheet, which is worth knowing if you want to see the data before it moves. Select the charts you want, choose Export Selected Charts, and in the export form click Edit ASCII to set the columns. Chart name, date of birth, time of birth, time zone, place, latitude and longitude are the ones that matter. Turn Chart Points off, so the file carries birth data and not planet positions.
