CorelDraw (X7) to QCAD/CAM (Version: 3.28.1.0 (3.28.1)

Hello folks

Can someone explain me how to get files from CorelDraw X7 in QCAD/CAM version:
3.28.1.0 (3.28.1), on a MacOS big Sure without the curves becoming square. I despair…

A step by step guide would be very helpful.
I don’t know my way around that well… but my Arcdroid is on its way to me and I want to get started right away:)
