# Challenge Number 4 is live! 🚧

Time for another modeling challenge — and this one comes straight from the street. 👀

## What you’ll be building 🚦

For **Challenge #4** , your task is to model a **traffic cone** using the provided dimensions and reference images below.

Your goal is to recreate the object as accurately as possible while working within the limited toolset allowed for this challenge.

**Reference drawing:**

 ![Traffic Cone - Drawing](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/3X/8/9/89ea6409c4ba973110847ba5dd94cda4af10e07a.png)

**Photo reference:**

It might look simple at first glance, but getting the proportions, transitions, and overall shape right with a restricted set of tools could make this one more interesting than you expect. 😉

## The rules 📋

The same restrictions from the previous challenges still apply.

Your **Design History may contain only:**

- **Sketch**

- **Extrude**

- **Construction tools**

That’s it!

Any other modeling tool appearing in your Design History will make the submission **invalid** , so think through your strategy before you start building.

There may be more than one way to get to the final shape — choosing the right approach is part of the challenge.

## How to submit 📩

Once your cone is complete, take a **screenshot of your project where the final object’s volume is clearly visible** and submit it through the link below:

👉 **[[SUBMISSION LINK]](https://docs.google.com/forms/d/e/1FAIpQLSc-10AtSU--ukLdDhKSe0Cq9HaKTb8laRtB_t5-raA_7UxFjQ/viewform)**

Please make sure your entry follows all the submission requirements described in the form.

**Deadline: September 10th, 23:59 CEST**

Every submission will be checked against the challenge requirements. Valid entries will earn points and move you further up the leaderboard.

## Points 🏅

- **10 points** — complete the challenge

- **6 bonus points** — successfully complete the model

- **5 points** — 1st submission

- **4 points** — 2nd submission

- **3 points** — 3rd submission

- **2 points** — 4th submission

- **1 point** — 5th submission

- **3 extra points** — after participating in 3 challenges

- **10 extra points** — participate in all 5 challenges

## Keep the solution secret

As always, **please don’t post your completed solution or reveal the final body volume before the challenge closes.**

You can absolutely discuss the task, ask questions, exchange ideas, or talk about different modeling approaches — just avoid giving away the final result.

If you hit a roadblock, use the community. A small hint might be all you need to find a completely different approach.

Ready to put your modeling skills to the test?

Good luck, have fun, and happy modeling! 🚧📐🚀

I can see the revolve tool looking at me from the toolbar, single tear rolling down its cheek. 😂

Good chance I’m missing something here, but I kinda think this distance can’t be derived from the drawing. Am I being stupid?

I’m stuck on that dimension as well. Without an overall height for the cavity or relation between C and E in some way, I’m not seeing how we can calculate the distance…

Ah that length is tricky but you can figure it out with the constraints provided!

We hope you are enjoying our 4th challenge. Here is a helpful tip for solving this one.

IMHO, that’s not a tip. It’s a required parameter that was missing from the original task.

I have to agree here. I also figured the “correct solution” was to do with the cones having to stack, but for a practical construction you’d surely ad some measure of tolerance or clearance. I think this should have been specified in the drawing.

This can’t be a tip. There is no constraint or measurement to derive this the measurement from the original design blueprint.

I thought it was that but it is not actually, the cones stack but this does not define the missing dimension.

No, it was his first one! 😊

And maybe his last.

What is 1.311.9mm is that 1311.9mm, which is way too tall for a traffic cone. 1.31metres

I just started trying to work Season 2’s challenges and find it difficult to find what tools are acceptable for challenge 4. What is the definition of construction tools?
