Problem cutting open paths

[muzzagb]

I'm having an issue when trying to cut open paths
Firstly, I am using Sheetcam for my drawings. Some of my designs require folding, so I have been drawing lines where the fold will go.
When I open the drawing in sheetcam, in either DXF or SVG format, the drawing opens fine. All the details are there.
When I run a new plasma operation, only some of the open paths are are highlighted to be cut.
I have played around with offsetting open paths and leadin on open paths, but nothing seems to make a difference.
This is turning my hair grey (or greyer).
Any help would be greatly appreciated.

Have you got it all on the same layer in sheetcam?
Go to the edit contour button, then rt click in the drawing and select all. Then go "move to" (whatever layer you want everything on)

Then generate your cut, select the layer with all your lines on it and cut that layer.

If you are trying to cut just lines there is no offset you cut on the line (no offset).
Offsets are for inside or outside starts that are closed.
