0.01 seconds at 15.43 feet represents 0.000000748 feet. So a possible error of half that amount would be 0.000000374 feet or 0.000008977 inches.
PS
I laid out a mcmansion almost 10 years ago (and several since). The plan called for a 45 degree angle between the house and garage. It was really almost 48 degrees.
Later that week I met an architecture professor from mit. I begged him to teach his students mathematical closure. His eyes got all big, he was appalled for how his profession worked in the real world. He got red faced when I told him building designers knew how to close a building better than architects...
Even a correct and good line/curve table on a plat should be a crime. JMHO I would rather see it labeled on the line or leadered in.
Can be overused, yes, but they are sometimes necessary to present the data in a useful manner other than creating many detail drawings of a segment of a line on the face of the drawing, having to much congestion or using small poorly reproducible lettering sizes.
jud.
Quite often, line and curve tables are the only reasonable option on a really congested drawing. Leader lines get overused and you end up with a VERY trashy drawing. The ultimate goal is to present the data in the clearest manner possible.
Leaders are fine for engineers and architects, but are unacceptable to cartograhic types. Never saw leader lines in a 15 minute quad, SADLS map or JOG Chart. Got an engineering scale slammed across my knuckles in carto school in the Army. Evidently my instructor went to Catholic school with one of those ruler wielding nuns on his butt.
Sister Mary "Atilla the Hun" Catherine?
Must be the one!!
