CAD Puzzles & Riddles

I'm pretty sure I made only 1 feature, but I guess SW isn't on my side today...

I don't think that's quite right.

My bad!

I missed a row & a column while counting.

Although the concept is the same, I'll upload another screenshot after tweaking the model.

Done!

I hope the solution is not sweeping a cross-section through a very complex 3D sketch

It probably will be. :/

While that takes some effort and achieves a low feature count, I would sure like to see a more innovative approach.

Yahya; does your method work with round wire, or must it be square cross-sections?

It can be made with any shape: square, rectangle, circle, hexagon, you name it!

This is how i made it.
