Should I catch the error?
Calculate the exact value

addz cumInThk
wallniche 5, 1, 1,
0, 0, 1, cumCoThk,
-ac_wallhole_width/2, 0, 15,
ac_wallhole_width/2, 0, 15,
ac_wallhole_width/2, ac_wallhole_height, 15,
-ac_wallhole_width/2, ac_wallhole_height, 15,
-ac_wallhole_width/2, 0, -1

As shown in the picture below, the structure line is not erased and comes down.

Or do I have to cut all the wallholes and make a new one?
This is a problem when it comes to insulation.

If it is the bit of black line showing below the orange one then there is not much you can do about it other than change the pen thickness.

In hairline everything will look perfect - this is what you should be looking at when working things out.

When true line weight is used, the lines get thicker with the hairline in the centre.

The ends of the lines become round and extend beyond the length of the hairline by half of the line thickness.

There is noting you can do to stop this except for using thinner pens.

Today I express my gratitude to you.
If you use a thin pen, the concrete structural line will be thin, so it is not possible. ㅠㅠ

How the wallniche changes, and without using the wallniche, you have to remove all of the wallholes and create a new object, but if this is also an insulator, there is no solution yet. ㅠㅠ

If you have time, I would appreciate it even more if you could answer my many unanswered questions.
Have a happy time today... ^^
