I have downloaded the Terrain Mapping Toolbox in order to use in a project that was assigned to me. However, I want to define it as a permament toolbox in ArcMap, similary with the main toolboxes that are offered through ESRI(e.g Spatial Analyst, Data Management, Conversion etc.).
I tried to place it in this directory (C:\Program Files (x86)\ArcGIS\Desktop10.4\ArcToolbox\Toolboxes), but didn't work. I thought that locating Terrain Mapping toolbox at the same directory with the rest main toolboxes, that would work.
Is there any suggestion which will enable me to set Terrain Mapping as a default toolbox?
