New Reach Terrain for Existing Model

[lnegherbon]

I have new terrain for a section of river reach in an existing model. I can export cross sectional data and alignment from AutoCAD easily enough matching coordinate systems; however, splicing the new alignment section into the existing reach eludes me. Any direction would be much appreciated.

Thanks,
Logan

There are a number of ways,
1) create a new geometry file and then in your original geometry file: file>import geometry. Your river and reach names need to be identical in both files. There are options within this that you can select such as what sections to import etc.
2) if replacing just a few sections just copy and paste over the data in the previous or if supplementing them use the “add cross section” under cross section editor.

Outside of full section import there isn’t a way to just import a portion of a cross section if that is what you are inquiring about. You’ll have to just delete the points in the existing section and copy past the new points in.

double check all your reach lengths after you import to verify if they are correct.
