Challenge #77: Extending Spatial Lines

Alteryx Alumni (Retired)

Happy Monday! Last week's solution can be found HERE!


In this week's challenge, a communications company is doing an analysis of fiber runs in the network. The current wiring needs to be extended a certain distance in each direction in a straight line. Take the provided lines and extend them 5 miles on each end. For more intermediate users, create a macro so the user can input the desired extension length for each run.


The output should include:
1. Name of the fiber
2. The original spatial line object
3. The new spatial line object
4. New length of line

Here's my solution. Attached both workflow and macro

I went with finding the slope of the original line and extending it out.  I also decided to use the spatial tools vs. using the spatial formulas.


Good opportunity to practice with spatial tools that I rarely use.

My solution! I started by going down a trigonometry black hole... that didn't work. (Yet.) So I ended up borrowing a few ideas from @gnans19 and @alex, and then focused on streamlining it once I got it working.


I'm convinced there's a trig way to do it though. Stay tuned. :)

Here is a route to get slightly more accurate coordinates, I am sure the expressions could be improved to be even more accurate.

Similar approach as one of the workflows above. Good challenge to play with the Spatial tools!

My answer doesn't match exactly, I think it's cause my solution is missing the Smooth tool.

I started down a trig path too, and will get there (just struggling to remember trig!!).

When that wasn't working, found the same solution as many others, with circles and distances. I suppose that's more of a geometric/geospatial approach.


Still working on doing this with formulas.... to be continued.....

Like others I decided to try and figure this out using Trig &  Geometery and then I realised than I have no idea what I'm doing, so I stuck to what I know..

I had a hard time with this one.
