I created a multipoint file using the tool LAS to Multipoint in ArcMap. After it was done processing, I went to my geodatabase, right-clicked and attempted to create a terrain. However, the wizard that's supposed to be under "New"->"Terrain..." is not allowing me to click it.

Any ideas why it won't allow me to do make a terrain?

  • Do you have the 3D analyst extension? If not you can't create terrain dataset or TIN.

  • I do, yeah. That's why I'm confused. It works for everything else

    Did you turn on the extension in Customize -> Extensions in both ArcMap and ArcCatalog?

  • Wow, did not know it had to be turned on in both programs. Thank you so much!

    @Jakub I think it may be worth writing that up as a short answer

Turn on the extension in Customize -> Extensions in both ArcMap and ArcCatalog? Even tough you may have a licensed extension, you still need to turn them on in each application.
