Sometimes, when the generated plt/ai/dxf format vector file is imported into EZCAD software, the incomplete Hatch will appear. This is because there is no closure during the drawing process.
The solution is as follows:
1. Convert the PLT vector file successfully imported into the Ezcad into curves, and ungroup it.
2. Automatically connect the curves with the phenomenon of “missing filling”.
3. Then Group again.
