I am trying to create a TIN layer based off of a DEM. I watched a video about going to the "Base Height" section of the layer properties and selecting "Floating on a custom surface" to create a terrain model.
However, every time I have tried making a TIN, I get:
Maximum number of data points has been reached
I looked at these two sources, and performing their suggestions still didn't help me create a TIN:
- Converting raster to TIN and large section did not convert properly?
- https://geonet.esri.com/thread/56678
I'm just wondering why it is not working. I have tried changing the maximum number of points, the z value, converting the raster to multipoint then to TIN, and creating a terrain to turn into a TIN. None of these processes worked for me.
Is my data too big to create a TIN in ArcScene?
It is 2.16 GB.

In an official answer I got from ESRI, they were stating that ArcScene cannot handle TIN files larger than 2GB. Their advice was to subset the data as @PolyGeo mentioned in his answer.
On the other hand ArcGIS Pro does handle it, so give it a try. I managed to process bigger files then yours and everything was fine.
When getting the error with maximum points I always enter very large number(several orders in magnitude then what I need), just to be sure the number of points wont be and issue.
To answer your question Is my data too big to create a TIN in ArcScene?, the answer is Yes!
