profile graph in ArcGIS pro 2.0

[junewong]

I am using ArcGIS pro 2.0 with 3D analyst extension, and i have created a tin layer including elevation data.

But i have no idea why the profile graph is showing zero ? The blue profile line is created by ready-to-use tools "Profile"

When i was using ArcMap, profile can be created by using 3D analyst toolbar.

Thanks.

Profile graph.... doesn't it require 3D line geometry?

[XanderBakker · Accepted solution]

As Dan already mentioned, this will require you to run Interpolate Shape—Help | ArcGIS Desktop first and then create the profile graph

Thanks!

And the next question is how can i export the graph to excel?

the export icon as shown is only for images.

and the attribute table only contains shape_length.

did i miss any steps? i am new to Arcgis Pro.

Many thanks again!

FeatureVerticestoPoints with an Add Geometry Attributes to get the coordinates then

Table to excel depending on your license levels of course.

or FeatureClassToNumPyArray then standard numpy savetxt to get it to a csv format which allows for x, y, z to be read in

Hello Dan,

after working with Feature vertices to points, the attribute table is like this,

am i working right?

thanks.

you now have the points... at this point you can proceed with

• the Add Geometry attributes to get the point information to add X, Y and Z values
• and calculate the cumulative distance using the field calculator on a new double field. (or in a secondary program)

If you add a field called SeqDist type double, appropriate precision and scale, set your program to python parser use the below and you can now graph distance versus the Z value

def dist_cumu(shape):
    global x0
    global y0
    global distance
    x = shape.firstpoint.X
    y = shape.firstpoint.Y
    if x0 == 0.0 and y0 == 0.0:
        x0 = x
        y0 = y
    distance += math.sqrt((x - x0)**2 + (y - y0)**2)
    x0 = x
    y0 = y
    return distance

# in the expression box use... python parser of course

# dist_cumu(!Shape!)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

hello dan,

But i have failed to do this. do i miss any steps?

i am currently using the arcgis pro (trial version: advanced level with all extensions) before getting the full license.

many thanks again!!

looks ok, go old school and add 3 double fields, X, Y and Z.. Use the simple field calculator expressions

!Shape.centroid.X!, !Shape.centroid.Y! and !Shape.centroid.Z!

It is a featureclass I assume and not something else

Also, I trimmed of 3 lines for the function, so add them as in this image to initialize the start values for the distance calculation

Just what I needed, thanks!
