I am having trouble retaining information in The Road Template Layer. Some of the data is being deleted by another unkown operation/function. I suspect it could be when I run contour/triang and the erase previous contour entities.
When I have different .rdn files in the same job it is impossible to retain the data I need. I have to re-run the road network to get the data back. This is made more difficult if I used the road breakline data elsewhere. If I copy the road breakline data to another layer that data was also being deleted. I found the solution was to construct polylines from the road breaklines by using polyline follow.
Is there a flag Ican set to stop this problem?
