Topic: copy "altitude" value into "elevation" v

[dom]

Hi all,

I need help in reading the "altitude" value in property's of a polyline.

I then need to write that, into the "elevation" value, in the properties of
that same polyline.

Thanks in advance.

I don't see an "altitude" property in a pline.

Yeah, there is another Dominic!

I believe that I have 2D polylines.  I select one, and then right click it,
then select properties.  In the last section "OD:VMEL_CONTOUR", the first
element is "ALTITUDE".

I want to copy this value from there, and change the "Elevation" in the
"Geometry" section of the properties, to be the same.

I have been able to get the X and Y values from the "Geometry" section
using:

Code: [Select]

(setq thelist (vlax-get-property theobj 'coordinates))

But have been unable to get the Altitude.

Does anyone know how to get this value?

regards

Are you using a 3rd party app? Or are you getting these dwg's from someone who is?

I'm using Autodesk Land Desktop 2005.

Don't know what the people who originaly made it were using.
