> How do I convert a polyline in acad to have an elevation?
Polylines have elevations. Sometimes that elevation is zero. Just double click on the polyline and the properties dialogue box will pop up. Change the elevation parameter from zero to what you want it to be.

Alternatively, you could use the MOVE command to move the polyline from 0,0,0 to 0,0,z - where z is the desired elevation.

this is working! thanks as always for the rescue!

Be careful using the MOVE command for this purpose. The current OSNAP setting and drawing conditions could produce undesired results. Changing the elevation using the properties dialog is safer.

As I recall, that can be shortcut to
MOVE @0,0,N
Where N is your vertical displacement.

Here's one example of automation produced a long time ago.
