I think you mean 3000 points which is a type measurement. PX is pixels and applies to bitmaps.
I just tried it and there does appear to be a 3000 point limit to point size in Coreldraw. The workaround is to convert the text to curves (Control + Q). At that point you can continue to enlarge the graphic.
lol. Not a water tower.
It's cheaper for my family busniess to buy a plotter and do it ourself, rather than pay 2000+ a trailer, which we have been paying for years.
Thanks for the tip on the font size. Now I'm able to create the right size. Thanks.
