Hey everyone,
I am having problems when I make2d. Whenever I ‘make2d’, lines are not connecting from my polysurfaces and some internal lines are showing even though my ‘hiddenlines’ in the make2d properties tab is turned off. I don’t know if there is something wrong with my geometry? I have tried to explode and then join my model but this did not seem to work. I have also tried to booleanpslit and booleanunion but this didn’t work. And again, I have run ‘check’ and everything seem to be fine.
Has anyone else had this problem? If so, please could you help me?
Thank you
