3D Geometric DXF Design

I’m preparing a laser-cut, layered wood artwork and need a clean DXF vector file that opens directly in CorelDRAW (2021) without any additional tweaking. The design will be used purely as decorative art.
The shapes I’m looking for are hearts, circles, flowers, and teardrop shapes.
For the heart, circle, and teardrop designs, I’d like them to be 3D (relief) on one side and flat on the other.
I’ll attach reference images to clarify the style.
What will make the file usable for me:
• The artwork must be true vector paths only — no embedded rasters — with all contours fully closed, so the laser software reads each shape in a single pass.
• Please organize each cutting depth or layer on its own layer inside the DXF, so I can quickly assign colors and power settings in CorelDRAW.
• All lines should be single-stroke where possible; anything intended for engraving rather than cutting should be clearly separated.
• Keep the design fully scalable, but draft the initial artwork at approximately 400 mm × 400 mm to allow clean resizing up or down.
If you work in Illustrator, AutoCAD, or similar software, that’s perfectly fine — just make sure the final export opens fault-free in CorelDRAW 2021. Once I’ve test-cut a small sample on plywood, I’ll confirm everything is good or request minor kerf adjustments if needed.
Looking forward to seeing how you bring layered geometry to life!
