Hello every one.
I have recived a 3d survey (very large, very detailed) in native autocad format (vanila autocad). There are a large number of arcs (1000+) with differing 3d points, that is, the arcs are not parallel to the UCS.
Is it possible to convert the linework into
There are numerious topics about how to fix 3d arcs, by flattening them. This is not a solution in this case. the 3d geometry MUST be maintained.
Thanks in advance,
Adam.
Welcome to the forum!
I do not have access to acad at the moment right now. But you could easily test it by copying one of the arcs somewhere and create a featureline from it. If the feature line performs the way you want, then you can deletet it and do it for the others.

I tried some experimenting with this and didn't get very far. If you pedit an arc that isn't parallel to the UCS you get a polyline - that isn't parallel to the UCS, and you cannot convert that into a 3dpoly or featureline or anything else that would be useful for surface construction.
