EZCAD3
Advantage:
1) It can contour relief, like the picture below.
Disadvantage
1) Can’t adjust the stl relief design in software, for example if you need engraving 40*60mm, you need put a 40*60mm design in software
2) Focus deepth not depth as lenmark, but similar
3) Lenmark precision theoretical can be 0.025, ezzcad3 can’t, but its for very high precion work, for your working, they will be same
