Line feature needed?

[James_In_Utah]

Hi,
Is there an XML loaded drawing feature that draws a line from a position at one altitude (mid-air collision location), to another location on the ground (impact site)? I looked at LineFeature and PolygonFeature, but they don't seem to support points at different altitudes. Any help would be appreciated.
Thanks,
James

So, maybe there isn't a way to draw a line from a point in the air at one lat/lon to a point on the the ground at another lat/lon? I have this working with KML, but would like to do it with XML. Any help would be appreciated!
Thanks,
James

It can be done in WWJ without a problem.

That's good. I'll wait until WWJ does KML and runs my plugins. For now, I can do this with linestrings in KML but thought it might be easier to produce products that just show up when someone opens WW if I did it with an XML. We also need to support the goto and lookat type functionality.

The KML is being worked on.

"goto and lookat" is there.

Getting the plugins to work would require the most time.

Line features are available via xml, but not very well documented.

That works. It does take elevation on the lat/lons. Thanks!

The color and LineWidth don't seem to do anything though. I think I fixed the color in the KML Parser for LineStrings, but couldn't get the width to work ther either. Has anyone tried fixing this?

Thanks,
James

Also, DistanceAboveSurface doesn't seem to do anything, and I added <AltitudeMode>. I didn't try the extrude options, but I'm pretty sure they work.
Thanks,
James
