Well, that's exactly my problem, how can I change the height (elevation)?
If I want to edit the line - this is the popup I get:

Hello all,

Any ideas on how to set the elevation on lines - as I would like to use the "polylines" in order to draw the electric wires/ UTP / water pipes ... but I can't 'elevate' them as I can with furniture and other object. Am I missing something?

Thanks in advance!
