we use a lot of checker plate so we experience same mess too... 25 out of a 100 of any kind of hatch works for us. 80 times out of a 100 we experience total crash when we try to hatch anything. So bad I have a giant note on my screen "SAVE B4 HATCH!!". We have learned if it is important to have hatch, we explode detail, manually draw whatever shape, then hatch works perfect...if not it just way more simple to leave it plain
We hope you get help and some figures it out....
we wait and watch for answer
