	"can be used to have, for instance, a photo of the part overlaid on top of the "
	"model and use it for drawing curves somewhat accurately.</p>"
	"<p>For this purpose, a specific photo has to be taken of the part; it should "
	"represent the part as true as possible to the actual camera used for editing. "
	"The image should be taken from straight above the part, at as an orthogonal "
	"angle as possible. It is recommended to take a lot of pictures this way and "
	"select the best candidate.</p>"
	"<p>The image should then be cropped with the knowledge of the image's LDU "
	"dimensions in mind. The offset should then be identified in the image in pixels.</p>"
	"<p>Finally, use the \"Set Overlay Image\" dialog and fill in the details. The "
	"overlay image should then be ready for use.";
