Thank you so much for your question. Here is my input:
1. I chose 3.4 format, the decreasing gap and jagged/broken trace happened
I tried to select "De-Embed" on outline layer, but it was still filled in gerber.
2. The close of boundary is "yes" in CAD, still met that unfilled problem, but I found if I change "Arc deviation (mil)" from 0 to 0.005, then 2,3 below I mentioned is not an error.
Is somewhere that I setted wrongly? I really appreciate you are doing to help me out. Thanks so much.

The boundaries of my AutoCAD drawing did not line up perfectly with the gerber and curves that I drew came out as jagged lines in gerber.
