Slope arrows

[jenniferchavez]

Slope arrows are pointing the direction we pick in stead of the direction the slope is on a surface.

Any ideas how to make it work right.

I assume you are talking about surface labels here. Anyway, here is how you do it:

I have a problem putting in that value in the rotation angle. We get an invalid input.

See the attached image.

Am I missing something?

It does not appear that you have defined the expression.

1. Start by right clicking on "Expressions" and selecting "New..."
2. Enter the name "Grade Check"
3. Enter a description, if desired
4. Enter "IF({General Segment Grade}<0,0,pi)" as the expression
5. Pick "OK"
6. Open up the label properties again
7. For the direction arrow component you should be able to pick the new grade check expression in the rotation angle.

This might help (look at the entry from 12/19/2007):

When I enter the IF statement, I get a parse error. I've tried different words, but nothing works. Any idease?

Yes understand that the label (arrow) direction is counter intuitive, and pick you label points accordingly.
If you are using TWO point labels.
(and that rotation value is an EXPRESSION created under the label style not input directly as the roation value in the style.
So you must creat the expression, then use that expression in the style.

Are you using the f(x) button in the Expression builder to 'enter' your IF statement?
