Is it possible to merge such kind of curves in one layer?

[anto]

When i use Layer-->Geometry-->Merge curves i got such result.

I think your problem is that a layer can have only a single Stroke defined (except via the Appearance panel) and therefore you have to lose one of those two incompatible strokes.

Thanks.

I just did an experiment. If I use Layer-->Expand Stroke first and then Layer-->Geometry-->Merge curves it works.

Yes when merged together as a Curves layer that should work. Should usually then result to the same, as performing a centerline vectorization with some centerline tracing capable vector tracer here ...

When performing that with a tracing tool, using one which supports centerline tracing is essential here, in order to get no outline vectorization of an image!

If you Expand Stroke before Merge Curves then you will get something which looks like it has worked but it hasn’t really (depending on how you think about it) because the two curves are now different curves; they are both the non-dashed outlines of the original curves, rather than the original curves.

You can see this by changing the Stroke after you have done the merging.

This might be okay for some things but any later modification needed will, especially in the example case, be a real pain.

Multiple curves in a Curves Layer always have the same Stroke and Fill as they are ‘the same thing’; they’re basically a single curve which has ‘gaps’ in it.
