Zero thickness 2d elements

Hello.

Is it possible to create zero or very small thickness 2D elements from 1D elements? I am aware that creating zero thickness 3d elements from 2d elements can be done (in fact I've described the methodology a few years ago...), but I am looking for the same procedure considering 2d elements.

Thank you in advance for your kind assistance.

can you add a couple images on what you need? i'm sorry, i didn't get the idea.

Sure! Please have a look at the picture attached. Do I need to create another set of 1d elements in a different component, overlapping the original ones for using the menu I've highlighted?

Thank you for your interest!

not sure if i've followed you completely.

But you could use the 'drag' panel, select your nodes in a list, and them provide a direction and distance to drag and create the 2D elements (midmesh).

Thanks. I know you can do it by dragging the 1d elements, however you cannot do it if the distance specified is very small (let alone zero) even if you tamper with the mesh, node tolerances under "preferences".

Please pay attention to the "zero or very small thickness 2D elements" I've mentioned in my first question.

Thank you.

Just a quick update to inform you that I've managed to do it by providing a small distance of the order of 0.0001 mm (not zero as I initially expected). If I remember correctly I've used the "ruled" option from the 2d menu and specified the node path on two parallel lines with a distance between them equal to the width of the elements (0.0001).

The process is not exactly "automatic" because I had to intervene in order to delete and create the elements that were distorted, however the final result covered me (at least partially).
