How to delete dangling pieces of etch ? Only the right one is displayed

HI,

There are a couple of ways to do this, Manually and automatic. First thing save your board as a different name so as to work on that.

The manual method is to run a quick report so as to identify where those dangles are and then use that report to navigate to each dangle. Then manually
delete the antenna, dangling line.

Go to Tools >Quick Reports > Dangling Lines, via and antenna report. Click on the link in the report to navigate to the dangle, antenna and then delete them manually.

The other method is automated. Go to Route > Gloss > Line Parameters. Check Dangling lines box. Uncheck the other box's if checked. Click the gloss button to run.

After you run this, it's worth running a report to verify it got all the antennas and your etch looks good. Also update DRC to make sure there are no errors etc.

Best Regards.
