No other warnings or errors. Unfortunately, this warning code is NOT described in the Help file (3.15 P011).
I tried looking through "WCCOAascii_info.log" but didn't seem to find anything obvious (plus, my "WCCOAascii_info.log" is about 300'000 lines, so it's hard to look through it unless you know what you're looking for.
Only several days later I noticed that my Plantmodel tree was somewhat "corrupted". All the DP's didn't look like DP's but looked like unknown node types. Re-importing the ASCII file fixed the problem (now DP's look like DP's in the tree). I'm still unsure what ASCII Import warning code 79 means, maybe I have some other problems that I'm not aware yet, can someone from ETM clarify?
I wish that code was in the WCCOAascii Error Codes table in the Help file (like all other codes). That would at least point me in the correct direction for debugging...
