I've been having an issue with large complex fills, I find that sometimes the fill doesn't meet back up from where it left off, it just leaves the slightest gap that is very visible. I've tried different underlays, been trying to find if there is any overlap option but I don't see one. I am using Pulse Version 14. I will attach what I am talking about. This usually just happens with designs that are not standard shapes.

usa la opcion de traslapar linea que esta en control de calidad yo siempre la uso en 3

 

Yes, need add overlap. Usuallu i use 3-45 lines for big embroidery objects.
