Invisible Lines Become Visible In PDF

I don't know what this is or how to search for it so I'm starting a new post. Hope nobody minds ;) I have a piece of clipart of a banner that uses lines around the edges of the curves. When I export the banner as a PDF, lines appear on the PDF that are not visible on the Xara file, EXCEPT if I drag a line to a new location and keep the left-mouse button held down (as seen in the attached images). Some questions: Why does this line appear? How do I get rid of the part I don't want? Why does it show up in the PDF? And finally, what is the purpose of the dotted line around the object when I stay clicked on it?

Jim, could you post a xar file of the offending clipart?

I found a way to fix it. I found each offending "line" and clicked "convert line to shape". That eliminated the straight connector line between the 2 ends, so I don't have the bad file any longer to upload. But I still wonder what causes the PDF to show the end connector line, and what is the dashed box outlining the object when I drag the object and before I release.

That's standard Xara behaviour.

I don't understand how this can be standard Xara behaviour. Does every invisible attribute become visible when exporting to PDF? I never had this happen before.

I think Keith is referring to the dashed lines when you drag, which are a 'boundary box' of a kind to assist in placement before releasing the mouse button - they are visible when the object is behind another as I recall.

As for the other I don't know - but PDF does not handle everything that xtreme produces, especially if transparency or bevels are involved - it is not a xara format after all

Sorry - Yes, thank you Steve. I was referring to the dashed lines as you drag.

Thanks! One step closer to being an expert ;)

Do not relax! SO many steps are still ahead :D
