Hi Frank
I can't comment on coreldraw, but when using illustrator or dxf, lasercad won't show a fill on a vector drawing unless you have set the particular colour on the vector to be rastered. (at least it hasn't for me
) - it only picks up the outline colour of the cut vectors.
I try to stick to a predefined set - black raster, red cut, blue mark (low power cut) - you can use white over black fill for empty parts of anything that needs to be rastered. So, if you have a filled black circle with an inner filled (or unfilled even!) white circle over it, it will raster a black ring.
Beware, if you have previously set different colours to raster or cut, then it will remember them !!!
Easiest way around this to clear the 'memory' is to draw three rectangles - black, red and blue then set them to raster, cut high power and cut low power. When creating your coreldraw vectors, set the colours to rgb black(0,0,0) red(255,0,0) or blue (0,0,255) then when it imports, it will show a fill for rastering black and outlines for red and blue. I can't handle any more colours than that - brain is too old
))
Hope that helps.
Cheers
Neil
