Using OpenTD, is there a way to edit multiple elements without using a for or foreach loop (which essentially edits them one at at time) when these elements are somehow grouped (either in a submodel, layer, domain, etc.)? I know it's possible to do this bulk editing within Thermal Desktop, and I'm looking at how to do this efficiently in C#.

From the Getting Started manual, I've seen this done with a foreach loop:

foreach (LinearQuad q in quads)
{
q.CondSubmodel = submodel;
q.TopThickness = 0.01;
q.Update();
}

Additionally, in the code I'm writing, what I'm interested in is similarly implemented.
myElementList.ForEach(e => 
{
e.ThermoMaterial = ThermoMaterialName;
e.Layer = Layer.Name;
e.Update();
}

However, this method takes too long for my application and I'm hoping there's a way to shorten the element editing time using some type of group editing.

Thank you!

Even with the array-based code in Fortran, each element is individually edited. It just does the loop internally: fewer lines of code to compile and the most efficient method of looping (this would be a bigger benefit with multi-dimensional arrays). Unfortunately, there isn't a better option that we know of. Someone in the community might be able to prove us wrong (which would be quite welcome).
