Apologies for asking a question previously answered…

Someone asked this about a year ago, and Stacho or Martin provided an answer, unfortunately I can not find it in the forum archives.

The partial log file transcript below suggests to me that there is a minor problem with my wall drawing in or after [181] and a fatal problem with something in or after [186].

How do I locate the objects referred to by the numbers in square brackets?

(This particular one is odd, ‘cos it worked fine yesterday, and all my th-config files that compile individual components of this master file still compile perfectly – must be an inadvertent change I made somewhere…)

Thanks

Bruce

The `angle' between two identical points is undefined.

I'm zeroing this one. Proceed, with fingers crossed.
