Curve bridge with two open curves and a small gap to bridge?

[mawag01]

I don’t know, how I can prevent to combine the two curves along two polygroups with curve bridge brush:
I draw a curve along the violet polygroup and the second along the brown polygroup to get a bridge between them.
The gap between is small.
Under “Frame mesh” in the Stroke-Palet polygroups and frames is set on.
My problem is, that, when both curves are near together, they will combine to one curve so I can’t make a bridge.

I’ve tried to set curve-snap-distance to the loest possible value, also dicreased the draw size to the possible minimum, the curve projection range to 1, and the curve-edit radius to one. But nothing helps.
Also increasing the overall size of the subtool with deformation-size doesn’t help. The gap between the two polygroups becomes bigger, but also the subtool becomes bigger, so the same problem happens.

Any idea?

Thanks

Have you tried making your ‘draw size’ smaller than the gap?

As written above, I dicreases the draw-size to the lowest possible minimum, not always to one. At longer curves it must be a little bit higher than one to achieve the needed length.
At this short example, a value of one or two is possible. But after snapping to the border, the lengtth of the segments automatically goes to the length of the polygons at the border. Of course, I didn’t jet try to first subdivide several times to get shorter curve-segments, because the the bridge has many many polygons and remeshing with zremesher with conserving the polygroups doesn’t really dicrease the number of polygons when many polygons are at the border of the polygroups. That’S in my opinion still a problem of zremesher. It should be able to preserve polygroups but decrease the number of polygons along the polygroup-border. That’s still not possible.

Is there no resolution for this problem or a workaround?
For a workaround, don’t only thing about the example on the picture. It’s only a very simple example to illustrate the problem.
It’s universal, concernig basically the problem to connect seamless two subtools, which are created with the extract-function, that means, they are double-sided with only a small spacing between the outside and the inside.
Then by delete hidden opened on the sides were they should be connected.
Always, when a certain amount of space between the ends of the two open curves is fallen short, the ends snap together and from two open curves one closed curve is builded.
