Please add the feature in Advance Steel to set tolerances on dimensions, as AutoCAD.
On AutoCAD the properties panel of the dimension allow to add Tolerances. Picture: 6_AutoCAD_Tolerances.png
But the Advance Steel Parametric Dimensions are unable to have tolerances. Not possible in Properties panel or Advance steel Dimensions panel. Picture: 6_AdvanceSteel_Param_Dimension.png
