layer not shows inches symbol

[nuwul]

Hi. 

I'm using mixed metric unit for project & use ANSI standard for spec. 

When assigning pipe tag number, the layer should follow the line number tag. However in my case the inches symbol not shown in layer list. 

So when generate isometric drawing, filename will appear ass 1_ instead of 1"

Is it because of my project unit?

Hi,

The " character cannot be used in an AutoCAD layer name or a windows file name.  The _ is being substituted for it.
