upside down contour labels

[surveyor]

On the last couple of jobs I have done the contour labels are printing out upside down, even though they look fine on the screen. When I have someone else print out the same job it comes out fine. The LABEL POSITION is set to MAKE PLAN READABLE. Any ideas?

I use acad 2006 / ldd

Contours are basically polylines. A label will follow the direction of the pline segment it's on. The only ways I know to make the label appear right-side up are either to explode the contour or to redraw it in the opposite direction. Does anyone have a better way?

In the Contour Style Manager dialog box, under Readability, there are two settings - Make Plan Readable and Label Positive Slope. Perhaps they are set differently in the different plots.

The Contour label alignment does have significance to those who know. The top of the text should be uphill, so when you are looking at the plan with the labels the right way up, you know you are looking uphill. Only one label on one contour is needed to discover uphill.

If you have to end up reversing the direction of a polyline/contour you could use the lsp below:

;;; RPL.LSP a program to reverse the direction of polylines
;;; Program by Tony Hotchkiss. Enter RPL to start the program.

(prompt
"\nType RPL to run command."
)

Have you had any more suggestions since your original posting?
Apparently the message is - just live with it even though one tries to be meticulous?
