I couldnt copy in the full code of my vector so i've attached an image, its just a normal vector

Answer 1

Your compiler warnings might complain about a RESOURCE_TOO_LONG (some path value). It seems there's a maximum for those.

The parser opens the string value, finds the R and doesn't know what to do with it.

You can either:

• simplify the XML (or the source material you used to generate it).
• split that path into two paths (probably adding a Z IIRC at the end of the first path to close it, and a M<last_coordinate> to the second to start from where it left). But really it'd be better to have a compliant source to start with :)
