Intersections of a fishnet

ArcGIS Pro 2.6

I have a fishnet of polyline segments that I would like to create intersection points from.  See illustration below. This fishnet is the addressing grid of my area of jurisdiction so the object is to have a point (mulitple points, actually) that has the coordinate values of the intersecting lines.

At the intersection of 200 South and 8700 West, I would like two points, one with the coordinates of 200 South , 8700 West the other with the coordinates of 8700 West, 200 South.  How does one go about doing this?

I looked at Point at every intersection which refers you to  Feature builder reference but I don't see the point at every intersection icon there.  

Suggestions?

Is it a "group template" you are working with?

Feature templates—ArcGIS Pro | Documentation 

In a group template, the Point at every intersection builder Point at every intersection generates point features at a specified offset at every intersection of a polyline feature you create in a map. The builder is available with point component templates when the primary feature geometry is a polyline.

That's were things kinda fell apart for me: I tried the group template but never found that point at every intersection builder...

Hi Joe,

If you're creating a few features, can you use the Intersection snapping agent while creating new point features?

The other option is to use the Intersection constructor tool found on the construction toolbar:

I'm honestly not sure why the builder reference is missing the 'Point at every intersection' builder, but it should be available if you have a line as the primary geometry when creating the group template:

I'll look into whether the doc needs to be updated.

Does that help?

Thanks,

Scott

Let me take another look at this Scott..

Scott Harris‌ : I don't see that intersection tool under construct:

I must be doing something wrong as I don't get the same options you show in templates:

Hi Joe,

Regarding the Intersection construction tool, it shows up on the Construction Toolbar when you are creating a point or line or poly. Open Create Features pane > choose the point template > choose the Point tool....

> construction toolbar will show up on the map (defaults to the bottom):

Regarding the group template, from your screenshot, click Apply and add in any point feature template. It requires Line as primary and a point as secondary "component".

Does that help?

Thanks,

Scott

Not much of this is making sense to me right now, but I'll deal with it...

Too bad the output for the table isn't what you want, but I have a point as mesh tool in my

Slow night... some election coverage going on

 def joe(z, xstep, ystep):
"""test"""
z0 = z.split(" ")
lft = "West {}".format(int(z0[0][1:]) + ystep)
rght = "South {}".format(int(z0[1][1:]) + xstep)
return "{} {}".format(lft, rght)‍‍‍‍‍‍

That might give you a start, and you could add a comma for splitting if you want, then make a left and right field for 2 column labelling. But you can mess with that if it gets you closer
