HI all - I'm really struggling with a Service Area problem in Network analyst. I have a layer of 510 points and I need to create isochrones of 20 minutes walk around them. The problem is I also need to adjust for walking speed and slope  and have the resulting polygons as individual layers. . Its a very large area - 710 kms sq. When I create my scaled barrier layer I have over 3 million polygons and Arcgis Pro has a maximum of 2000. 

I'm not very experienced in Pro so what I would like is an online tutorial/workshop (Teams or Zoom) with someone who really knows Network Analyst and can talk me through it step by step. I would imagine it would only take an hour or two and I'm willing to pay for the help. At this stage any help is appreciated !

Regarding your question about service areas: Since you mentioned limits for the number of polygons, I assume you're using the ArcGIS Online service as the network data source rather than your own network dataset.  Those limitations don't apply when using your own network dataset.  Also, it will be difficult or impossible for you to incorporate slope into your analysis without creating your own network dataset.  The ArcGIS Online dataset is 2D and doesn't include any slope data, and you don't have the ability to edit it.
