Coordinate Dimensioning

Hello,

I am using coordinate dimensions and I am using a reference line for my Y axis that is not the lower edge of the drawing. However, the ordinate dimensions I start with do not go negative when I insert Y dimensions that are lower than my Y zero line. How can I get them to go negative? I have tried manually adding a "-" in the ordinate dimension text but when I put the ordinate dimensions in a coordinate dimension box it erases the "-". Any advice?

 

Thanks guys,Coordinate Dimensioning.JPG

Try setting the configuration option show_dim_sign value to yes.

Eric, let us know if you get show_dim_sign to work. I cannot get it to work in sheetmetal or drawings.

You might have to add it in the config.pro file before opening the session.

I cannot seem to have it show up if the session is active.

Of course, you can always add the prefix "-" to each valid dimension.

By default, it should do this in dimension tables. This is a .dtl setting.

The values are the distance from the baseline. It is a shortcut for an ordinary dimension to the same location. While one might expect that a tabulation would need negative dimension values, there is no example of them in ASME Y14.5-2009.

All the examples of tabulation I've ever seen are first quadrant.
