To Map the Symbol Fonts
1. On the Export Setup tab, click DXF or DWG and then click Settings. The Export Environment for DXF or the Export Environment for DWG dialog box opens.
2. Click Properties > Text Fonts.
3. If required, modify the mapping of the Creo Parametric symbol fonts as explained in the following table. Creo supports symbol font mapping with AutoCAD GDT font.
Creo Parametric symbol font
Default value
Other mapping values
Symbol_ASME
symbol_asme.ttf
gdt
Symbol_ISO
symbol_iso.ttf
gdt
stroked_asme symbols
symbol_asme.ttf
gdt
stroked_iso symbols
symbol_iso.ttf
gdt
legacy symbols
gdt
symbol_asme.ttf
symbol_iso.ttf
Alternatively, you can set the mapping of symbol font in the dxf_export.pro mapping file so that symbol fonts are automatically mapped to the fonts specified in the mapping file when the Creo drawings are exported to the DXF and the DWG formats.
Follow this naming convention while adding symbol fonts in the DXF or DWG mapping file:
legacy_symbols
stroked_asme_symbols
stroked_iso_symbols
* 
The special characters of the ASME and ISO symbol fonts that do not have the corresponding characters in the AutoCAD GDT font are exported as stroked entities.
