Failed to triangulate surface when I try to use ViewModel measure

edit

I am trying to use ViewModel measure.
However, I get following error when I try to run the measure.

[utilities.geometry.computeTriangulation] Failed to partition polygon 
Failed to triangulate surface Surface 947 with 0 sub surfaces

I could run simulation using the .osm file. Thus, I assume there is no problem for .osm file in which I tried to run ViewModel measure.
Does anyone know what could be the reason why I get this error?
Thank you.
