If you have entered fonts onto your drawing but when you open them in AllenCAD they are missing, this is because rarely a zero length font file gets created. This causes fonts to appear to be infintecimally small. To correct this issue, follow the steps below.

  1. Navigate to C:\Program Files\Allen Datagraph\AllenCAD
  2. Search for *.shx in the AllenCAD directory
  3. Sort by size and delete the zero length file named “txt.shx” located in the bin sub directory.
