I have a question, I want to randomly sample within a polygon, the polygon contains some known points, and I want to randomly sample outside a certain range of these points, so how do I do it on arcgis pro?
You can try the following:
1. Select the known points.
2. Run Buffer tool with the distance (range) you need to create buffer polygons.
3. Use Erase tool to erase the original polygon by the buffer polygons.

4. Run Create Random Points in the remaining polygon.
Does that work for you?
Glad to hear. You are welcome!
It is work. Thanks a lot.
Hi Fred
Many thanks for your help, but there is only one constraining factor in the panel. I already put in my point features in it and set the minimum distance and the extent of the polygon features in the environment settings, the number of points randomly sampled is not enough.
Best wishes

Hi bangminli,
To create random points you should use Create Random Points (Data Management)
Hope this help you,
Best regards,
Fred
