How to merge DEM and export?

Question

Hy,

I'm a beginner with ArcGIS and I 3 DEM (txt file), that I saved in a unique file of ArcScene.

I need to merge them and to export in a format compatible with 3D Computer Graphic software, like Rhino, 3D Studio, ecc.

I'm very grateful if someone could explain me all passage to do this.

Thanks,

Samanta

Samanta,

Assuming your 3 DEMs do not overlap and you want to create a single raster with all 3 "stitched" together then you would want to use the geo processing tool Mosaic to new Raster. If you read the help on this tool you will see that you can save the results in many different formats, I assume one of them will be at least readable by your other software?
