hi,
I recall this happened to me when i created the elevation bounded to Scope box. it introduced the same behaviour. however, try to set the view depth based on Boundingbox and not CropShapManager
something like this:
var vbx = room.get_BoundingBox(null); //then change the Minimum and Maximum to identify the the Elevation start/End Point and the Depth //set the cropbox option true elev.CropBoxActive = true; //Remember to Regenerate the document here doc.Regenerate(); //finally assign the boundingbox to the view. elev.CropBox = vbx;
hope that helps
