Since updating the video driver, I have had more issues with crashes. I have been running with hardware acceleration off, but I am not sure if this helps. I particularly had trouble connecting a layer as an input to tool in a python toolbox. It was crashing every time until I moved all the data so that the path names were shorter. So long path names is definitely an issue. ... View more

I figured out a way to get all the routes for a set of links. I ran the identity tool between the end point and the start point of each which will serve as a many to many table between the links (after a dissolve).  I wrote a Python script that recursively looks through the table from the start link to the end link and writes out a link combination for each. Came up with about 2200 routes for the project I am working on.   Here is the recursive function:       def follow_connections_recursive(         self, this_upstream_link, start_nodes, this_route_string, destination_link):         # loop through input points and find start point         fields = ["To_Link"]         with arcpy.da.SearchCursor(             start_nodes, fields, "From_Link = '"+this_upstream_link+ "'") as cursor:             for this_start_point in cursor:                 this_link = this_start_point[0]                 #arcpy.AddMessage(this_link)                 temp_route_string = this_route_string                 this_route_string = this_route_string + '-'+ this_link                   if (this_link == destination_link):                     arcpy.AddMessage("Route : " + this_route_string)                 else:                     self.follow_connections_recursive(this_link, start_nodes, this_route_string, destination_link)                     this_route_string = temp_route_string             return ...

Paths to reachable locations would not be helpful. That is just the network. I am identifying end to end routes. ... View more

I have been asked to find a way to find all possible routes between a start point and an end point on networks of about 100 links. Many of the links will be one-way links to enforce forward progression. ... View more

Here is a helpful post about using barrier to effect different routes on successive runs. https://community.esri.com/thread/63897 I am experimenting with creating a point barrier for each link used in a route and setting it's mileage to the original miles * 0.1 as an added cost. The points stack up as a link is used more than once, so the cost keeps increasing. This does yield a nice variety of routes. The same route can get picked more than once, but I can filter those out. I wish I knew how many of these routes to generate before I can feel confident I have found the 10 or 20 shortest routes.   Without knowing how the routing algorithms work, it seems clear that they can't and shouldn't find every route before they identify the chosen route. So my original question cannot be answered by routing software. I think that an exhaustive list of possible routes is something that sounds useful, but would really just be a very long list of no value. ... View more

I have created a network dataset for this sole purpose in desktop 10.5. We do not use Network Analyst for anything else in the process. These networks represent imaginary routing opportunities and contain a small number of links, usually less than 100. The routing problem has one start point and one endpoint. We can make most of the links one-way to prevent looping or non-forward progressing routes. We would like to generate a list of possible routes for analysis outside of Network Analyst. ... View more

I'm using it to extract raster files, so no need to convert further. ... View more

The iterate files tool will work if you set the file extension in the tool to "E00". Don't put a dot in front of the "E". Then the Import E00 python tool in the toolbox will accept the file as a proper input. use "%Name%" as the output file. ... View more

What is the donut solution 1.In Layout view, create a graphic rectangle that goes out the edge of the page. (can use guides for this) 2.Create another rectangle the same size as the Data Frame, align to the data frame Select rectangle 2, then rectangle 1, and choose Drawing --> Graphic Opperations --> Subtract. You will now have a square doughnut graphic that frames your Data Frame. 3.Send the new graphic to the back 4.Send the Data Frame to the back 5.Set the graphic to have the same border you want your Data Frame to have. Now when you export, the square doughnut graphic will mask anything that hangs out of the Data Frame. ... View more

I have also encountered this problem in a new version 10 database. Here is a very goofy solution: In Layout view, create a graphic rectangle that goes out the edge of the page.
