Dimension Ordinate

[majora]

I'm running AutoCAD 2000 and I'm confused why CAD doesn't display the ordinate dimensions corresponding to the Cartesian coordinate system. For instance if I create a point at X-4.0 Y5.0 why doesn't CAD display the dimension as such? Is there something I'm missing or not setting up in the parameters? Thanks for the help in advance.

Do you mean negative values don't show as negative? This aspect was discussed on this forum a few months back. I don't recall if there was a solution for that.

I do not believe there is a solution to that. I think there are some lisp rotutine that can do what you wnat, but basic autocad does not place negative dimensions.

A dimension is simply a distance between two points, and as such the negative is usually meaningless.

It would sure make my job easier and more accurate, I sometimes write programs for a small burner and I use CAD to get my points. Having a negative value show up in dimensioning would lessen my chances of making a mistake. Oh well, thanks for the help.

Chech out these. The second is an already written LISP routine, while the first walk you through the steps of making your own. I have not used the xycoords.zip file before, and so can not vouch for how it works.

Hope this helps.
