Can't figure out info from the screenshots I'm afraid...?

Capture9.PNG shows the crash occurs because fields is null.

Here are step-by-step instructions to create the problem:

• Run Component Builder and open the Spatial Definitions tab
• Click Edit | Row | Add to get to the Select Type(s) dialog
• Click to select row 3 Element Set Polylines and click the green tick
• Click the Item button in the new Spatial Definitions row to get to the FluidEarth2.Sdk.ElemenetSetPolylines dialog
• Click on the button in the Elements row to get the Polyline ElementSet dialog
• Click Edit | Row | Add
• Click Edit | Vertices... to get to the ElementSet Vertices dialog
• Click Edit | Row | Add

As a workaround, sufficient for my immediate needs, I have changed the code at the point of failure so that it reads:

if (fields != null)
{
if (fields.Count > 0 && int.TryParse(fields[0], out nIndex))
nElement = nIndex;

if (fields.Count > 1 && int.TryParse(fields[1], out nIndex))
    nVertex = nIndex;

for (int n = 2; n < fields.Count; ++n)
    coords.Add(double.TryParse(fields[n], out coord) ? coord : double.NaN);

}
else
{
coords.Add(0.0);
coords.Add(0.0);
}

Oh boy…. Well, if the fix works…
