Measure the slope of a line?

Slope cannot be calculated in a 2d file. Slope is relationship of the change in elevation to the horizontal distance. There is no elevation in a 2d file. The provided basic macro requires a 3d file.

Not true. Macro reports a 2D slope based upon Delta Y/ Delta X but 3D slope based upon Delta length/Delta Z.

This version adds a place text above line in the middle - only uses 2D slope in this version.

Caddcop.. did you modify the one I posted as now it labels where as mary just wanted measure... nice one

Now can you edit it to make it ask user keyin 1 or 2 for % or 1( rise) in X( run)  ratio ( .. I tried but it wrecked it!)

but this does look a lot like the original haven tried it but will it still measure 3d slope after your mods...

My post is simply a slightly modified version of the original. It still echo's 2D (and 3D) slopes, but only uses the 2D slope as a label.

I had one a while ago that did that. I will see if I can locate it.

What you need in these, is a check against a rotated view as this version will give wrong result as written. There are alternatives to get the slope in any view orientation, but I have always struggled with that type of code.

What I imagine in a finished macro, is a dialog box that opens after accepting the line and in the dialog box is the slopes with radio buttons so you can select 2D or 3D slope as a label and options for % slope, rise over run, run over rise and different labeling options - above, below, by origin or in a leadered note.

CAD COP I have that one I think it was by Tim shoemaker of the TMC  but it is compiled version of bas and needs 2  macros but it only works in XM not  8i.. slopeset.ba and Slope.ba

the Slopeset.ba  works in 8i but not the label slope which is slope.ba,

Several years later, it turns out I would need a tool similar to this to speed up my work. I edited the VBA to calculate DeltaZ over line length. I commented out the old code and the "-" label because I did not need these for sidewalk ADA work. So if someone in the future needs this, see attached.

Edit: Not sure why the forum prefixed the file name with "0882"
