I have surface created from an xyz point file, today I had to extend the surface but the new data was in a .asc file. I edited the surface definition by adding dgm...no problem, however the surface was data referenced into another drawing (B) and post edit drawing (B) won't open? I went back and deleted the new data and then drawing (B) was ok. Can anyone point out where I'm going wrong ??
