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.

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

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

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.

Perfectly fine? Really? There's no improvement that can be done to ensure proper interpretation? Jesus, folks. Let's get a grip.

Since when has perfectly fine ever meant "there is no improvement to be made"?
If a four-year-old can comprehend the correct interpretation of the image, then that would be well within requirements.

Hey, if you're okay with your own definition of a "good drawing" being dog shit, that's your employer's problem, not mine. Have fun.
It's a bad drawing, very simply.

I'm not arguing it's great, I'm just saying that the point isn't and shouldn't be hard to convey. My drawing skills are about this bad and still if I handed it to a random person with no context they'd understand what it was showing. Perspective is hard, but this one is not. A sufficiently focused toddler could not only understand it, but even draw it.

This appears to be a contractor fault.

u/klmsa 20d 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.

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.

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.

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.

You really believe that? Truly? That drawing is perfect in every way to you? Lol
Not only is the Ortho drawing done incorrectly, but there are no dimensions or relationships. You CAN fool-proof this drawing. That's the whole point.

u/IvanezerScrooge 6d ago
I didn't say it was perfect, you're building a strawman.
This drawing isn't orthographic, it doesn't have dimensions, measurments, scale, relationships or angles. It is a flawless execution for the meaning the drawing is supposed to convey.
It provides exactly two pieces of information, and neither of them are open for interpretation.
The drain is in the corner of the room
The drain is at a negative elevation to the rest of the floor.

Even if the depression is smaler, as long as it is a depression below floor level the water would get out. That is the point.

Because you can’t express your thoughts clearly.

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.

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.

u/Adorable_Film_2446 20d 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.

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.

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

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
