Hi Bill If it helps (unlikely), I have had a project where the Loch model has (had) just such a spike, one hundred or so metres long, angling about 20 deg upwards. For more than 10 years the model had this spike, and from time to time I tried to troubleshoot it without luck. I have had other similar cases as well. I looked up some outputs compiled January this year - it seems this spike is no longer present. So there must have been a change in the algorithm in recent years to resolve this. There has been no survey or drawing activity in that part of the cave or model since about 2008-2010, but I concede that edits more than 100 m away (from the spike) in the model could possibly have had some effect. I notice that other Loch rendering artifacts seem to have been resolved also.
Are you using a recent version of Therion? I'm using 6.1.8, but unsure what it would have been in January. Bruce _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
