Question: Arch building technique

[M2m]

This has been bugging me for some time and I need help

Is there a way to fill the gap:

Basically I want to have a yellow colored curved line embedded in the wall. Any way to do it ? Am I missing a part ?

Thanks in advance

That part unfortunately does not exist..

Maybe you could use a hose piece? It would add some texture though.

Could you use a stack of not fully engaged 1x1 plates? Or even tiles if you have something behind it to help keep them from falling out.

Perhaps a stack of 1 x 1 round plates would work if Vorkosigan's techniques doesn't work.

That's kind of interesting that it doesn't exist.

I mean, it's 3x3 studs, but in brick/arch numbering order, it works out to 1 x 4 x 2.667

A 1x3x2 is the one beneath and a 1x4x3 isn't round on top or bottom.

I was trying to think of a way to use a 3x3 disc, 3x3 dish, or 3x3 round plate, but those would only back-fill the opening, not give the smooth surface I suspect you want. if there was a 3x3 macaroni brick that'd be close, maybe tiling it would be better, but that doesn't exist either.

Certainly an interesting gap in parts.

Would a stack of 1x1 tiles be large enough to be an illegal solution?

I think he/she want to make in LDD (because as i see he/she usually build with LDD), so it will be really hard to make that or even impossible.

Oh yes, that would be impossible to do in LDD! I had forgotten about that.

Thanks for the feedback.. Bummer Lego Group "forgot" that part

Anyway I have 2 solutions in LDD

The left looks a little like a sad attempt, but the right side looks like a cool little detail on purpose!
