Limit Tolerances - Upper and lower limit both positive values,

Hi there,

 

I am trying to apply limit tolerances on my drawing.  For some of the components I want to show dimensions for I want both the upper and lower limit to add (be positive values) to the dimension.  I cant get AutoCAD to make both the upper and lower positive..  It wants the lower to be negative.

 

Eg,

 

Diameter is 16 (basic diameter)

 

I want to show the following:

 

upper: + 0.023

lower: + 0.012

 

The result I'm trying to achieve is;

(Diameter symbol) 16.023

(Diameter symbol) 16.012

 

This will be used for holes and shafts etc.  The above example is for a "n6" Heavy Push Fit (for a brass bush).

 

Likewise, some other components require two negative numbers so its the same problem again just the other way around.  I have tried trying to edit the dimensions once they're there but it wont allow it.

 

 

Also - regarding the diameter symbol... AutoCAD thinks that the edge of my round Bush (i.e. a striaght line) is a straight line.  Is there any way of getting the diameter symbol in there too even though I'm not dimensioning an actual circle?

 

Maybe its a case of entering it manually and trying to establish a little system myself to try and make it look consistent.. yelpRobot sorprendido

 

Thanks !!!
