THE PROBLEM
“Couldn’t find centerlines to generate a corridor around. Ensure that centerlines are set correctly.”
Finch 3d a promising AI-powered tool for architects.
and here’s the Problem:
-
There’s no visual guidance on what a “centerline” is supposed to look making it very confusing to understand what to do next even for an architect
-
No tooltip or hint on how to set it up (may be blinking icon)
-
No default examples or even a suggested fix .
As a UX designer with an architecture background, I know how important it is to let users stay in the flow. But moments like this can halt that creative momentum.
​
What Could Improve the Experience:
​
-
A visual guide “Centerline Guide”showing how to correctly set up centerlines or better the second option which is :
-
Interactive hint or “Fix it for me” and “show me how” option
2.1. Smart error recovery: e.g.using the AI engine “We’ve auto-added a centerline. Edit it here."

Role: UX Designer with architecture background
KEY GOAL
Improve Finch 3D’s UX by adding clear visual guides and AI-assisted fixes for centerline setup to reduce confusion and enhance user flow.
MY ROLE : UX Designer and Project lead
How Could Improve the Experience:
​​​​
A Step-by-Step Visual Guide
​
-
Clicking on “Centerline Guide” opens a helpful modal with text and visual instructions. It explains what centerlines are and how to draw them.
Here you can see my High-fidelity mockup of “Centerline Guide”

UNDERSTANDING THE USER
2.Fix it for me or show me how to create a centerline:
​
Drawing the Centerline.
The guide also gives a visual walkthrough:
- Select the Pen Tool
-Draw a straight line through the middle of the corridor
Here, clicking "Show me how" launches an intuitive walkthrough that demonstrates exactly how to draw a centerline

Smarter idea
If possible:
2.1. If technically possible something even smarter could be discussed with developers:
An AI-powered prompt like
AI has automatically added centerlines to your design.”
or better yet
“We’ve added a centerline for you, feel free to adjust it if needed.”
here is High-fidelity mockup AI DID IT FOR YOU! “AI has automatically added centerlines to your design.”

Problem
Confusing error message about centerlines with no guidance, disrupting user flow.
Goal
​
Make centerline setup easy with clear visual instructions and AI-assisted fixes.
​
Solution
Added a “Centerline Guide” with step-by-step visuals and interactive hints.
Innovation
​​
AI auto-adds centerlines and offers editable prompts for smoother workflows.
Impact
