<p>This is just how the mesh is being triangulated for display. If you want to control this you could triangulate the mesh in Rhino and swap edges to get the desired diagonals. Be careful though, as a triangulated mesh would behave differently when the edges are made into springs. It may be better to keep the quad mesh as the input to SpringsFromMesh, and make a copy which you triangulate and input to Geometry.</p>

<p>Yes, that's it!</p>
<p>But I was wondering how it is possible that the mesh at one of the catenary lines is very smooth while the mesh hanging at the other catenary line has triangles (where it hangs)...</p>

<p>Ah yes, it was missing gravity applied to the mesh (it was only on the cables). With that it gives more the shape in your original post:</p>

<p>Hi Daniel,</p>
<p></p>
<p>Thank you for the response.</p>
<p></p>
<p>Indeed the mesh is now included in the structure with the catenary lines. But the problem is that the mesh is now no longer in the squared surface (image in previous post).</p>

<p>I think the goal is to sort of drape a mesh over the two catenary lines so that new catenary lines are formed between the corners of the square mesh (the edge lines of the square plane also turn into catenary lines)... I don't know if this is possible..</p> Hi Stefan,

<p>Hi Stefan,</p>
<p>The key thing is to make the mesh edges also into springs. You can do this by extracting mesh edges, or use the included SpringsFromMesh component as shown.</p>
