Blootoof, what did you import?

Raster images which are also known as bitmapped images do not contain any information about edges, curves, or lines. They consist of binary 1's and 0's only. Files in gif, jpg, png, tiff, and bmp are some of the many raster formats. Importing one of those file types will only show the bounding edges of the raster image, the rectangle.

Xara3D needs vector objects to tell it what shape to display. A vector describes edges, curves, and lines.
