Please help! Quickest way to resurface spoilboard

Hi i am trying to resurface my spoilboard, in graphic-cad I would simply hit the option to resurface, but I understand on qcad this is not an option.
I tried making a line 50x at .1 distance and it mostly did work, but it took a long time and did not work perfectly.

Are there any easier ways to achieve this? I used graphic-cad for 30+ years and no longer have access to it so im trying to adjust to this new software.

From my understanding of what a spoilboard is, a sacrificial work surface, you probably will need Qcad-cam, is that what you have ?

yes that is exactly what a spoilboard is and I do have qcad-cam! Do you know specifically how I can achieve this?

Thanks in advanced.

Unfortunately I do not know how that might be done, hopefully someone with cam experience will be along that does know. Ideally you should have posted in the Qcad/CAM section - QCAD/CAM - QCAD Forum

Hi,
See my reply on the duplicate of this post in the QCAD/CAM section.
