Question about closed paths - lines

[Sampson Jones]

O k , when I m done with a drawing I close curves, combine , save file , dxf export tool to sheetcam . When I go to set up the cuting operation some of the closed paths will not start and end in one continous cut . I have looked at this art work by zooming in to see if there are any broken lines but I never see any . Some closed paths cut in one continous cut . The same thing happens on some open lines . Could some one do a step by step on what I 'm not doing correctly ? Thanks !

That can be hard to detect since corel will fill it as if it is continuous.

In the pic, you can see a break has two node handles in one place, and the status says it has 2 subpaths.

Corel X5 and X6 has a join-nodes tool that will fix that automatically.

I have x 5 is there some sequence to do to use the join nodes tool Gary ?

It works best to combine everything first.

It doesn't correct overlaps.

Have a look at Gary's reply on this thread, helped me understand the problem. As is mentioned in another thread kudos to Gary, always a great help.
