drawings end up way too smal

hey guys, i need some help.
i've being trying to make some nice projects in coreldraw and then converting them in mach3 to make them. but they end up instead of 24 cm like 1.5cm and also he seems to make them in mirror reflection.
i use coreldraw 11, i save the file's as plotter files and convert them in mach3.
anyone has a idea how to fix this?

Just a thought, apologies if you've looked at this. When you save as a plotter file, there must be some option in there to "scale to paper size" or similar. If it thinks it's printing (plotting) eg to A4 size paper wouldn't it scale the whole drawing to fit?

Again, apologies if you've looked at this.
