Hello Noel
To do this you have to open AstorDetailsBase.mdb from the...Graitec\Advance Steel\2010\Kernel\Data, using the table editor from MT orMicrosoft Access if you have it.
Open the AstorDetailsBase.mdb and look for the table"TextSizes" in here in the first column add the next availablecounter and in the second column you have to put the value you need for textheight in mm (e.g. 3/32 has to be 2.38125).
