BORDER, BORDER2, BORDERX2, CENTER, CENTER2, CENTERX2, DASHDOT2, DASHDOTX2, DASHED2, DASHEDX2, DIVIDE, DIVIDE2, DIVIDEX2, DOT2, DOTX2, HIDDEN, HIDDEN2, HIDDENX2, PHANTOM, PHANTOM2, PHANTOMX2.
TPC draws these lines the way AutoCAD does.
When you export a DXF or DWG file, TPC writes the AutoCAD line types to the file.
When you import a DXF or DWG file, TPC tries to match up the AutoCAD line name with one of the its own predefined AutoCAD lines.
