When processing vector graphics, the lines are very thin, about a few tenths of a millimeter wide. What if we want to make the lines of this graphic thicker?

1. Copy and paste the image

2. Lock ratio, enlarge

3. Select two graphics, and then through the alignment function, make the two graphics are center aligned

4. Select two graphics. Subtract at overlap through combine function.

5. Engrave the graphic. Then you will get a thick line star shape frame.
