I'm compiling some cruise data and I have a 23.3 inch ponderosa pine with a broken top at 73 feet (estimated total height is 95 feet). When I attempt to compile it, Assisi fails to estimate the diameter of the broken top with the following message:
Diameter at broken top failed. Volume not calculated.
Any ideas on why this error is occurring and how I might fix it? Do I need to try and estimate the diameter myself?
