laserCAD / corel file question

Hi,

I am hoping someone can help with a frustrating 'issue' I have when importing a file created in CorelDraw V7 into LaserCAD.

When I create the file it looks like this in CorelAttachment 395043but when I import it into LaserCAD it looks like this Attachment 395044

The design should be red for cutting but in laserCAD it is black which I use for engraving.

It must be some hidden lines in the design but I cant for the life of me figure out where they are (a layer somewhere!). I have attached the corel file in the hope that someone can help because this hapens on some files and not others.

Thanks in advance,

Graham
