Well, this is not yet implemented, but as far as I remember, you are not the first one asking for these features. I think, it would not be very difficult to implement it, but there are some technical issues, that need to be solved first. 1. What data needs to be stored. So far I see: feature type (falut, layering, fold axes?), srike and dip 2. Where exactly would you like to enter these data. Maps or centerline or both? If it is a centerline - then these data would be aattributes of the station - which position needs to be measured first. If it is map, then these data would be attributes of a point, that is positioned in the map (=> it's 3rd coordinate can not be given exactly). 3. How to plot these data. Are there any standard symbols for these types of measurements, that can be used in the map? In the 3D: how to construct these planes? Each measurement will be single small plane? Have you already seen some 3D models like this, that could be used as a template? Some time ago I have tried something similar, but it was not very successful - my 3D model was a mess of planes, in which it was very difficult to see what is what. Regards, S.
