When i use the AutoCAD WS app on my iPad to view my drawings, none of the refs are showing. The drawings with xrefs view perfect when viewed in AutoCAD WS from my macbook pro app & browsing on safari. They also work on my pc when browsing with Firefox. However, they do not view correctly when on my iPad. You can see the layer names in the layer command. However, you can not see the lines on the drawing-in both model and paper space.
