Time for the next challenge!
**What you’re building**
Create a parametric sketch of centered buttons inside a rectangle with fixed dimensions. By modifying three driving variables, your model must seamlessly transform from State A to State B without breaking, shifting off-center, or producing errors.
**The rules**
Fixed Dimensions: A, B, E, F and G
Driving Parameters: C, D, and Number of Buttons
⚠ Important: Design history tree should only contain Sketches and Extrusions. The use of any other features will result in an invalid submission.
Submit your CAD file through this [link](https://forms.gle/4Dpye8UeaRyt6uZm8) **by the end of the week on Sunday.**
Your results are going to be shown on the leaderboard after the submissions are evaluated.
**Prize pool:**
If you haven’t submitted your entry yet, here is exactly what you are playing for:
- **🥇 1st Place Grand Prize:** a **3Dconnexion SpaceMouse** to take your modeling workflow to the next level.
- **🥈 Top 3 Finishers (1st–3rd Place):** A **giftable Shapr3D Pro Subscription** (perfect for a friend, colleague, or to extend your own design flow).
- **👕 Every Participant:** Win **exclusive Shapr3D merch** just for stepping up to the challenge.
- **🏅 Every Participant:** Earn a limited-edition **digital community badge** to showcase your achievement on your profile.
Put your parametric skills to the test, submit your design, and claim your rewards before Season 1 closes!
**Scoring reminder**
Complete the challenge → earn 10 completion point
Complete the challenge successfully → earn 6 success points
First 5 people to submit gets → 5-4-3-2-1 points
Stay consistent across the challenge → after 3 participations you get 3 extra points, after all 5 participations you get additional 10 points
As usual, questions are welcome here. Good luck! 🍀

I might be the nearly man in this. Almost had 1 and 2, but was learning. 3 I had the general just of it but my hardware did not like the hexagons for some reason. Now in 4 got the sketch working perfect but the solids flagging in history because switching between 3 and 5 results in missing pieces.

Is this rule valid for this challenge ?

I would think so. It’s perfectly doable with just sketches and extrusions.
