The curved cutaway should match perfectly with 98252, 98224, 4198, 2302, and 98223.
This part matches perfectly with 98252, 98224, and one half of 4198.
This part doesn't match with 2302 and 98223 because they use a slightly too large cylo and make up for the discrepancy with a quad.

Welcme to the Parts Tracker, Peter!

Are 98223/2302 and this part matching in real life?

The part is fine, I am just asking you to create a 18652s01 file without the front face to cater for the one printed version of this part, better do it right now.

Thanks for welcoming me. Yes, in real life parts 98223 and 2302 match the arch perfectly both in curvature and the center studs. Too bad the digital pieces do not.
Thanks for the advice to create the subpart. Still learning how to do it properly.

Bottom curve needs to be changed. See discussion here:

Curvature now follows that of parts 98223 and 2302 and also the upper half of 4198.
Curvature does not match the bottom half of 4198. The bottom half of 4198 is wrong - should be mirror of its upper half.

Orientation should be updated (pending final decision of thread https://forums.ldraw.org/thread-28741-post-56949.html#pid56949)

i think this one counts a "Arch" and should stay in this orientation (like the other arches)

Most likely going to be counted as an arch and therefore will not require changes in orientation.

* line 29 : The flat subfile is scaled in Y direction.

Removed scaling from flat primitives as suggested. Removed superfluous BFC INVERTNEXT command as suggested.
Removed a few T-junctions in subfile as suggested.
