Hello Again,

First, I would like to apologize for having left this thread dangling unresolved for such a long time.

I hope the people who were so kind to lend me a helping hand back then are still willing to resume this thread too.

You can make the layer non symetrical (layers menu), and mirror that layer, a new layer will appear with the same shape but in the negative area of the model, that layer can be modified like any other layer and you can modelled what ever you want.

I tried this in vain, I mean mirroring along the vertical at CL (i.e. Y offset = 0) into a *new* layer.

Well, the deselection of the symmetry check box in the originating layer0 and the mirroring worked fine.
However, what I don’t get accomplished is that the mirrored hull side ends up in a new layer.

I started renaming the initial layer0 into “Hull Port” and, as mentioned, toggled off hydrostatics and symmetric from its properties.
Then I added a new layer (which strangely defaulted to the name “layer2” where I would have assumed it to be named “layer1” if my arithmetic doesn’t fool me),
which I renamed “Hull Starboard” and which I selected to be the active one.
In its properties I also removed the checks from “hydrostatics” and “symmetric” and assigned it a complementary colour of that of layer “Hull Port” to make the distinction conspicuous.

But I haven’t found the knack to fill this “Hull Starboard” layer with the mirrored control grid.
Instead the mirrored stuff ends up in the same layer from where it was mirrored, i.e. layer “Hull Port”, while layer “Hull Starboard” remains void, even though layer “Hull Starboard” was the active one during the mirror operation.

Regards,
Ralph
