Hi Randy,
The extra lines problem on elevations and rendered outline views is not an issue on any printer that can be set to 300 DPI but usually only Laser printers have this setting (and most PDF printers).
The problem has been not been fixed on V15 or V16 but has just been fixed (last week) on Envisioneer 7.2. Envisioneer is the parent program and TFP V16 equates to Envisioneer 7 (but the 3D part only). Usually any updates on Envisioneer will flow through to TurboFloorPlan a little while later, so we may possibly expect an update to V16 and it would logically include fixing the 'extra lines' problem.
However, some updates happen to Envisioneer that only involve Envisioneer itself (things to do with the Worksheet Plan Printing that is not available in TFP) so an update does not always follow, unless there are major fixes that DO affect TFP. Envisioneer update 7.1 has not appeared (yet) as TFP 16.1, so Env 7.1 and 7.2 could be rolled together into a TFP 16.1 if there are other major things that affect TFP. The 'extra lines' does but whether they will view this as critical remains to be seen. Both Envisioneer updates were total program replacements becasue of the nature of some of the fixes. This may not be warrented for TFP, if the 'extra lines' is the only issue. Time will tell but it will obviously be a part of a future V17.
In the meantime, if you print to a PDF printer, such as PDF24, you can set it to 300 DPI and the extra lines will not appear.
