Image Draping with XWMS

Hi,

I using PowerCivil SS4 version where I would like to use a SWMS file and drape it over the terrain.

I followed the procedure mentioned in the enclosed document.

Issue is, as soon as I switch the draping on, the Image goes off. I tried I it on another file, where it did show the image, but still didn't draped it.

Has someone faced similar problem? Could there be anything wrong with the XWMS file I am using.. if yes, how do I find that out?

Regards,

Anupama
