MeasureMax Plus installs a file on the hard drive that can be read through adobe acrobat.
(I think this acrobat is also installed in a zipped format, or check the MeasMax CD). The extension is .PDF and I think the file name is Cadpath.pdf. This file contains a tutorial as well as a list of entities that CadPath can read.................let me know if this helps. Call me if you still have problems, or post another message, or call Advantek's help line.
