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:
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:
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.

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!
