Comment 4 for bug 209296

I think drag and drop acts exactly like import, because you are dragging the contents of the file into the present document. Import *has to* ignore some of the stuff in the document, like the page boundaries (bounding box?) because otherwise it would not function as an element of the existing page the document is being imported into.

It seems that whatever information is intentionally being ignored is also causing problems.

There have also been two bugs that are in a very small way related to this, as opening a PDF file would result in either upside down elements in the picture (one bug) or upside down text boxes started subseuently (another bug). But definitely in the second case, importing the PDF did away with any problems with upside down elements.

So if we can nail down exactly what is being ignored, and how that relates to your road, then that will help.

The best thing to do is to delete elements from the picture one by one (saving different versions each time) until you get a version that does it and then a verion that doesn't, and post both of them. This is about finding the simplest test case, which will narrow down the possibilities of what needs to be fixed. Someone may know how to fix it (I don't).
