>>Can Vertical Mapper be set to honour breaklines when interpolating a TIN
I have been informed by a VM specialist (mtogr) that breaklines can be implemented in VM by converting the breakline to closely spaced points. Then use the points in the interpolation. You have to know the value of the 'breakline points' and be very very careful with the distance to the other point, because the TIN interpolation might create significant under/over shots. In some cases this approach will work in others it will not.

No, experiment with the TIN interpolation settings is the best you can do. Northwood/Maconi/MapInfo Corp. has been told for years, to support break lines in creating of VM grids. The future is still obscure for VM, with every thing going to be converted to .NET, I think you will see no updates to VM in the next few years. Another go is data manipulation with the VM stamp method, where you stamp/merge one grid onto/into another grid. I have see environment people in my company doing very nice data manipulation with river systems by stamping different depths onto a river delta.

Hi Vertical Mappers Can Vertical Mapper be set to honour breaklines when interpolating a TIN? Clipping the resulting grid is not sufficient for what I need to do.
