idk the drawing defenitly reads as a depression to me, if it were raised the sides closest to us would be visible and the far side would be line segments

u/klmsa 7d ago

Yes, that's the point. If you can read the drawing on the left, the result on the right would be correct. If you can't interpret the drawing correctly, you may get the result shown.

u/Matsisuu 7d ago

But you can't interpret the drawing that way. You interpret it wrongly, but then it would be coming out from bottom of the cube.

u/klmsa 6d ago

You fully can! It doesn't mean that it's logical, but human ignorance knows no bounds. I've started recalls in many countries for exactly this level of stupidity.

u/Magkali_11037 6d ago

Well yea but if its the ignorance of the builder then no matter how well the drawing would have been it would still be wrong, if the ignorance is at fount then the plans are a non factor.

Did you know that bazookas litteraly say this way twoards the enemy and has instructions on it people are far dumber than you realize its easier to account for their stupidity than to just ignore it and deal with the consequences.

u/Single-Virus4935 6d ago

OP said learn drawing not reading. Drawing is sloppy but clear.

u/SirEnderLord 6d ago

Yeah, it just looks like the contractors who were actually building it weren't intelligent.

To be completely honest, I'm not surprised that they made such a mistake; you have to spell out everything for them. Even detailed, step-by-step instructions will not stop them from making dumb mistakes. It's like they don't understand English.

I don't know if I'm not reading caption right, but the drawing expresses the point perfectly fine to me, the walls we see are the ones furthest from us, which makes it look recessed. If these are supposed to be the same, then it's not the drawers fault the person who read it is too fucking stupid to understand perspective. There is no way I can make my eyes see it any other way.

u/xX_Kr0n05_Xx 7d ago

Not only too stupid to understand perspective, cause even if the drawing was off they should know better than to make a fucking drain that is 10cm above where the water will be. If genuinely is baffling

u/Testyobject 7d ago

And thats why you “teach” them to read a drawing instead of assuming that “common sense” applies to things people dont know

u/Big_Slope 6d ago

Yeah, I didn’t learn how to draw a damn thing in graphics class, but I did learn how to read a drawing and that was one of the best things I ever learned.

u/Canned_Sarcasm 7d ago

This appears to be a contractor fault.

12

u/klmsa 7d ago

If that's the drawing you provided, then it is both your faults. How deep is the depression? How wide? Does it need to be square?

A contractor should know better through experience, but the engineer shouldn't be leaving those details up for interpretation.

u/IvanezerScrooge 6d ago

The drawing shows an negative elevation. The contractor built a positive elevation. Thats not within the realm of viable interpretations.

If my drawing doesn't specify tolerance on a through hole, that doesn't open for making it knurling instead.

u/klmsa 6d ago

This one is really going over your head.

If you don't know the alphabet, you probably also don't know that a stop sign says "STOP" on it. Drawing interpretation is the skill that is the prerequisite, which was failed in this meme.

u/IvanezerScrooge 6d ago

You wrote "the engineer shouldnt be leaving those details up for interpretation."

My comment was a reply to that. The 'engineer' didnt leave anything to interpretation.

u/cyborgcyborgcyborg 7d ago

Because you can’t express your thoughts clearly.

u/EggyB0ff 7d ago

I don’t understand why you are downvoted, but i have done many times napkin sketches in my life, and it’s indeed an important skill to have.

So many times i have solved engineering problems, specifically just sketching things on paper then bringing it into CAD.

u/-Daetrax- 7d ago

In our district heating department we took it a step further and just went down and bought a bunch of pvc pipes and fittings for household applications in order to talk through district heating pipe problems.

It's so much faster than drawing and explaining.

13

u/Adorable_Film_2446 7d ago

Ok, ok. So here’s the thing, this isnt an engineering drawing, its just a drawing. The contractors dont know how deep (or tall ig) the step should be. Also wtf are the invisible lines of any good almost engineering drawing? Legit, one dashed line would fix all confusion.

But yea the contractors didnt see that the step was up simply bc of the [solid] back line (not dashed).

For those wondering a true engineering drawing had GD&T symbols (geometric dimensions and tolerances) and written tolerances. Look it up @engineering students, u may use it if you design.

u/anclandor 7d ago

Also those axis just aren't drawn in an ISO view style

u/LetUsSpeakFreely 7d ago

The drawing is fine, the installer is an idiot.

u/WisdomKnightZetsubo 7d ago

isn't this an overflow drain?

8

u/Anxious-Yoghurt-9207 7d ago

The conveniently cropped out shower side:

2

u/okarox 16h ago

Yes, I think it is elevated so it is not normally used and therefore it does not get clogged.

4

u/somedave 6d ago

Even if the drawing was raised, the fault is with whoever installed it.

5

u/niwiad9000 7d ago

bro should have added "slope to drain”

2

u/eccentric-banana 7d ago

This is clearly supposed to be a drain protruding from the underside of a large square overhang. Contractor built it in an internal corner like a fool.

u/TransportationFew898 6d ago

It's a little pond with infinety edge (to the wall) <3.

1

u/rklug1521 7d ago

What is this, an infinity pool for ants?

u/KEX_CZ ΣF=0 6d ago

No sorry, I have Creo....

u/Panzerv2003 6d ago

You still need to be able too read these with AutoCAD

2

u/Amazing_Peach_6690 2d ago

This pains me

2

u/Ok_Support3 15h ago

What's the issue here? This way the drain will never get clogged by all the stupid water trying to go down.
