Hello Gee,
As a fundamental point, please remember progeCAD or AutoCAD always draws 1:1 in theoretical "drawing units" which may correspond to whatever the design/engineer/architect wants a "drawing unit" to represent in the real world. Scale is applied to paperspace mviews/viewports for plotting to appropriate paper size.
That being established, you can create dimension styles for whatever you wish using the progeCAD _DDIM dialog command. (Also "Dimension" -> "Dimension Styles" from menu)
BTW, for actual command prompt input/output use the _DDUNITS command to set numeric input and display to architectural / decimal / scientific / fractional / etc as desired.
You can also search progeCAD help for these subjects by hitting the F1 key in progeCAD.
