Great mod! Love the concept of having to find and sketch the item first. There are two potential issues I have noticed so far:

-The items I sketch in the notebook are not appearing in the builder menu
-The builder's sketchbook doesn't seem to recognize some items (some lockers, the red tool chest, fences...)

Uploaded screenshots to imgur that try to illustrate what is happening, also to show that the sandbox options are set to both sketches and magazines. There were no errors encountered. Please let me know if you need anything more and I will try to provide it.

If I read the instructions correctly I think the items like the two sinks in the sketchbook should appear under Appliances_bathroom in the build menu, but they do not. Apologies if I am just missing a mechanic of the mod and thank you for what you do!


[Edit]
I got curious and launched in debug mode to see if I was able to see the recipes with the build cheat on but they still do not show up -- not entirely sure what went wrong for me so I am uninstalling and reinstalling to see if it will fix it.

i have the same issue of a lot of things not actually appearing in the build menu. quick guess would say maybe in the ballpark of 30-50%

the bigger issue i have though is that recipes dont get unlocked by sketching. hardly any of them. i tried with sketch + mag and sketch only but i can see the recipe in the build menu but the recipe icon is still red. not sure if this is a vanilla issue though as i also have an issue with stuff not unlocking that should unlock via level (in this case the stone chisel for example when hitting knapping 3)

after i found 2 magazines, the things these teach do unlock, so unlocking in general works, just the sketch unlocking not. no idea why.

stuff like the antique oven for example should be unlocked but its not visible in build menu at all, even after reading the mag.

and from the doors / windows magazine hardly anything appears in the build menu. only a couple windows (like 6-8 or something) but none of the doors. also, for windows like the arching window, those would need a wall with a fitting cutout as well, right? not sure if that exists

nevermind, i just read your post in the comments about the steps needed and i selected the show all qualities thing and then the antique oven and doors did show up.

that leaves only the unlocking issue for me. here is a screenshot to show that i sketched it and that i have the necessary skill to build it but the recipe is still red:

Same issue as described above, I can sketch and "learn" the recipies in the sketchbook but the actual building menu says I havent learned it. Only once I read the associated magazine does it unlock. I had used the sandbox setting mod to change the option from magazines only to magazine+sketches so maybe that is a factor? Ill test on a fresh save with the setting set on world creation to see if it makes a difference. Otherwise the mod is working great!

Them not being shown in the menu even if you learned their recipe/sketched them isn't actually a bug, it’s a built-in feature I forgot to mention.

Recipes you've unlocked (either by reading a magazine or sketching an object in a sketchbook) won't automatically appear in the build menu unless your character also meets at least one of the required skill levels for that item. This is intentional and designed to make the building process feel more grounded in progression.

If you enable the "show all building qualities" In the Build Menu option, you'll see all buildables, but even then, you can only build the ones your character has unlocked and has the proper skills for.

So in short:
Unlocking a recipe (via sketch or magazine) is the first step.
Meeting the skill requirement is the second.
Only when both are true will the recipe show up in the menu (unless you force visibility the "show all building qualities" setting).

I might remove this skill check completely because it causes confusion.

I got the same problem.. I can easy find the objects in the build menu. That is not the problem. The problem is that even it I sketches something, i'm still now allowed to build it, and the build menu showed that i haven't learned it and is just marked with red in the top right corner, and yes, I got the book on me. ;)

I also have the problem with the recipe not being unlocked in the building menu.
I have Sketch + Mags enabled in sandbox settings

I sketched the object and it appears in the sketch book which I have in my main inventory
I have the required skill level listed in the recipe in the building menu

So I can see the recipe but it has the red book icon in the building menu (indicating I have not learned the recipe) and the build button is inactive.

Hey, doors dont actually work normally? https://prnt.sc/uCniXfe_YUwh this is how they look when open. When closed they fit normally in the door frame.

Same issue as previous users; using sketchbook to "learn" the recipe for a Light Switch Right Side does not unlock the recipe in the build menu, noted with the red "You have not learned this recipe" icon in the top right of the UI. This is after opening & closing both the building UI & the sketchbook, also after a quit & reload, sadly same result.

To expand on this in case it helps; used the sketchbook on a tile that I had the magazine for as well (before reading it).
after sketching the red "You have not learned this recipe" icon was still present, reading the magazine that corresponded to the same tile then unlocked the recipe to be crafted

the flag "mode:destroy" are missing on the line 11 of "BuildablesExpansion_Recipes.txt". That duplicate the bucket when you craft a bucket of asphalt mix

Some decorations like concrete wheel stop and rugs have collisions because they don't have the property "isThumpable = false"
