Good morning Stuart
You are correct this error has popped up before on the Distance list, without obvious resolution. I understand what you are trying to do; iterating through different segment lengths in the two segmented transect designs. Can you tell me a bit more?
Does the engine succeed for all your segmented trackline investigations, or does it fail at some segment length?
Conversely, does the design engine fail for all segmented grid designs you try, or does it succeed sometimes and fail when segment length reaches some critical length (too short or too long)?
Given you can get some designs to work, it
doesn't seem there are problems with the shape file you are
using, so challenges are internal to the engine. If you want to
move the conversation off-list, we can come back to the list
with a solution (if we find one).
