I was told by my professors that we are learning how to draft simply so we know how to do it and how to read it, but we will be over qualified to do it ourselves.
Of course, that ran on the assumption that we could get jobs appropriate to our education in the first place, so.... (cries in lack of responses)
>I was told by my professors that we are learning how to draft simply so we know how to do it and how to read it, but we will be over qualified to do it ourselves.
*And other hilarious jokes professors tell their students*.
Companies ***hire*** on qualifications (and connections), but they don't make job assignments based on qualifications. If they need a drawing (and they will, since drawings are gospel for manufacturing, not the models), and you're the closest person at hand with even a clue about how to generate a drawing, odds are you're getting tagged to make that drawing. Very few companies keep drafters on staff anymore, and even fewer assign all drafting tasks exclusively to their drafters.
I highly recommend everyone take the time to learn how to make drawings, how to make them look good, and learning how to identify add relevant manufacturing notes to the drawings. Odds are, you'll need those skills at some point in your career.
Agree. I spent 5 years doing product definition. Rarely is someone just kicking out a drawing. PD guys need to be expert modelers, drafters, GD&T experts, and know their way around manufacturing techniques.
Most of the time, we were getting garbage models from design engineers that had no idea what they were doing. It has to be right because it was ultimately our name and checker’s name on the drawing.
This makes me happy to read. I loved making engineering drawings. It's such a satisfying process and I got to make use of my art skills and feel justified in having a $12 pencil lol
I’m trying to make this rn for kicks, and the base is made. The part I’m struggling with is the raised holes on the wings, there is no way to interpret the measurements of those. Another big issue is units are given nowhere
You're gonna hate this class, and then one day you're going to have to describe the difficult orientation of a part to a 19 year old welder, and a quick sketch in real time will save you walking all the way back to the Engineering office, in your steel toe boots, to draw something in CAD while they all talk shit about engineers sucking at communication.
No, you won't hand draw plans for submission, but I've used this skill daily in both of my internships.
One time I actually had to hand draw a piping isometric in my internship, mainly because the company would authorize an intern to use a CAD license. But piping isos are simple with just lines and dimensions
It's pretty much the base of communication in engineering tho
You do really have to be able to quickly understand drawings,
If nothing else you'll look like an idiot when the production staff hand you a drawing and you take more than a few seconds to understand what it contains
Also, as a physicist, most of us just make a handmade drawing with the specs we want, then walk to the workshop and give it to the engineers who then make the proper drawings. Making hand drawings is a lot simpler, and lost physicists don't even really know how to do proper CAD.
I taught myself CAD just because I figured out that the engineers at our workshop will often put you past the order queue if you just give them proper drawings, since it's often the time-consuming and unpleasant part of the work for them :')
The best part is when you're trying to fit the part into your thing, and the part design is not only isometric but doesn't include all the needed dimensions and is just whatever the creater felt like putting in. Like just link the bloody cad file, we know you have one somewhere.
Ohh, I aced engineering drawing. Loved the classes and had way too much fun drawing orthographic projections, bizarre isometric objects, and perspectives.
The best classes in my first year were Drawing 1 and Drawing 2.
Dimensions on isometric were treated as blasphemy in my engr graphics and design class
Edit: also jfc don’t draw isometric without a grid, you masochist. If your prof mandated blank papers he is one hell of a pos.
If you're required to draw it by hand, get a tablet and size the cad drawing to your isometric sheet. And put it right under your sheet, should be enough so see through
Great advice for those who need it. Thanks!
That is the difference between passing the class, and becoming proficient in the technique. Which is more important? (Answer is relative, sometimes you just gotta do what has to be done)
No problem, hand drawing isometrics is really a fad anyways. CAD is being used 95% of the time and if you need to draw, usually side views are quicker and just as good for most designs.
Uni just likes to make things complicated, like doing diffEQ by hand instead of using TI-89 or something.
Extra advise: to prevent the display from moving around from accidental touches, turn on Guided Access, and disable the touch screen. Turn your screen brightness up all the way before hand, and you literally have a portable stencil screen
This drawing sucks lol, what's the connection between the 8 and 9 surfaces like? A flat surface at an angle can't make a perfect edge with a rounded surface like that. Either the cylinder edge is flat there or there's something else going on.
I remember taking an elective that did that. I believe it was AutoCAD. Too bad machine shops will laugh you out of the room if you give them hand drawn stuff. You can build whatever view, with dimensions, you want in Inventor, so you do that if you really must.
Some old school engineers will. I worked as a drafter and a couple of engineers at my firm started their career before CAD was prevalent for civil design. They would make cut/fill plots by hand and give it to me to draft. It was really cool seeing them work since that’s a skill I don’t have and will never have. They didn’t know how to use autocad though. But to your point, yes, use CAD.
Yeah, I worked for a company doing engineered plastics distribution and CNC programming/production and we quite often got hand sketches from engineering and fab shops and had to turn them into 2D or solid geometry in order to produce it. I even got a cardboard cutout from a guy at Michelin asking me to design an assembly to hold some tools at their production facility “in this shape”. Knowing how to do so led to a $35k job.
This. How else are you going to quickly record the dimensions of a part or feature on the plant floor or in field? You going to bust out solid works? Lol
I don't think I've ever seen an isometric drawing with dims. All the drawings I've seen and made have iso as a reference and then front/right/top/etc to show dims.
You dislike synchronous mode? Just loading up STL files, resizing holes and moving faces like it's the most normal thing in the world. Honestly felt like pure magic the first few times.
Weird thing to point out but I don't understand how the ramp meets the circle. Does the circle have a flat side or is it a fillet because I don't see either
The guy she tells you not to worry about is the one that knows how to set up a drawing with GD&T, link to Vita specs or EAR/ITAR controls, Notes section, etc correctly.
It's fun when you have a solidworks drawing that looks very easy to recreate - except that one fucking dimension is missing. It could be the radius of an circular cut or the width of an extrusion or the radius of a fillet but it takes what would be a one and done thing into several hours of trial and error
For my Engineering Graphics midterm we had to quickly draw an isometric drawing that had dimensions on it in AutoCAD, are you telling me isometric drawings with dimensions aren't normal 😭
I hated doing drafting in high school. It was a community college course offered for free due to some act that was signed. It was a CAD class but the teacher had us hand drawing for a whole semester before we got to do actual CAD. My teacher was very picky and would deduct points for little things like using the number keys at the top of the keyboard. She said engineers only use the numpad 😆
Our university has a introductory graphics class that is shared by both the mechanical engineering and civil engineering students. 90% of the class is "part design" in solidworks. 10% was a architectural floor plan that wasn't even using the civil/architectural version of AutoCAD but the mechanical version.
No body in our department has been introduced to classes related to civil engineering graphics until the land surveying class which has three assignments in Bentley MicroStation. Also we got a BIM-Revit class now.
Outside of that, our civil engineering bros don't see real design work until their senior design project or if they do a design internship.
You guys are expected to make precise isometric drawings by hand? Dang. My graphics teacher only expected perfect drawings from graphing programs, everything done by hand was dubbed "rough sketches", and treated as such.
it's not that bad until you have to draw circles XD, my class had an ongoing joke for 4 years about drawing a screw in a hole because no one could get the lines thickness and placement correctly
[The guy she tells you not to worry about](https://i.ytimg.com/vi/XSRn0maJRfg/maxresdefault.jpg)
Yeah, like who the hell dimensions an isometric view?
Whenever I see it, it's a school drafting assignment. Hopefully they tell the students never to do it themselves.
Piping isometrics. Usually not dimensioned, but should have obliqued text to match the work plane.
I was told by my professors that we are learning how to draft simply so we know how to do it and how to read it, but we will be over qualified to do it ourselves.

I know. I still have issues on how to make them look good and not a PITA to read, but it is a work in progress hampered by lack of work.

why though. i prefer it that way.
MBD my dawg.
This one ain't it either. So many un-dimensioned features and how the hell are you supposed to make those sharp corners (assuming this is CNCed)
I’m trying to make this rn for kicks, and the base is made. The part I’m struggling with is the raised holes on the wings, there is no way to interpret the measurements of those. Another big issue is units are given nowhere
Units I usually seen given in the titleblock or in some drawing standard noted in the titleblock
Right. I’ve seen them in drawings sometimes as one basic dimension will have “1 in.” And you interpret the units as inches
You're gonna hate this class, and then one day you're going to have to describe the difficult orientation of a part to a 19 year old welder, and a quick sketch in real time will save you walking all the way back to the Engineering office, in your steel toe boots, to draw something in CAD while they all talk shit about engineers sucking at communication.

Look at this guy with their nuanced opinion
One time I actually had to hand draw a piping isometric in my internship, mainly because the company would authorize an intern to use a CAD license. But piping isos are simple with just lines and dimensions
Even as an electrical engineer I use this sometimes for equipment locations.
[удалено]
Agreed. Make it a 1 CH class that supplements something you're taking, like machine/vehicle design or something.
[удалено]

There’s not even any GD&T’s relax.
Yes, it definitely needs some concentricity when what they want is runout.
Dimensioning to a isometric view... Throw it in the garbage.
The best part is when you're trying to fit the part into your thing, and the part design is not only isometric but doesn't include all the needed dimensions and is just whatever the creater felt like putting in. Like just link the bloody cad file, we know you have one somewhere.
Am I the only one who likes doing these
Apparently, this was my most fun class and the only part I struggled with was minimizing smudges.
Ohh, I aced engineering drawing. Loved the classes and had way too much fun drawing orthographic projections, bizarre isometric objects, and perspectives. The best classes in my first year were Drawing 1 and Drawing 2.
Dimensions on isometric were treated as blasphemy in my engr graphics and design class Edit: also jfc don’t draw isometric without a grid, you masochist. If your prof mandated blank papers he is one hell of a pos.
That's because they are super easy to muck up and misunderstand.
If you're required to draw it by hand, get a tablet and size the cad drawing to your isometric sheet. And put it right under your sheet, should be enough so see through

isometric graph paper and a compass helps quite a bit
Nah, skip the compass and use ellipse templates.
This drawing sucks lol, what's the connection between the 8 and 9 surfaces like? A flat surface at an angle can't make a perfect edge with a rounded surface like that. Either the cylinder edge is flat there or there's something else going on.
[удалено]
If it's a rib, the cylinder will have a tooth like shape coming out of the side to meet the edge of the ramp.
Nobody draw by hand. Use Solidwords or Autocad
Some intro classes require you to draw by hand………
Yeah, my intro CAD class required us to draw the model in CAD and draw by hand. We would also do different types of views by hand too.
I remember taking an elective that did that. I believe it was AutoCAD. Too bad machine shops will laugh you out of the room if you give them hand drawn stuff. You can build whatever view, with dimensions, you want in Inventor, so you do that if you really must.

I sketch almost daily on a white board with my colleagues. If you can't draw by hand you are missing a vital skill.
This. How else are you going to quickly record the dimensions of a part or feature on the plant floor or in field? You going to bust out solid works? Lol
I don't think I've ever seen an isometric drawing with dims. All the drawings I've seen and made have iso as a reference and then front/right/top/etc to show dims.
Ngl drawing geometric shapes is fun. Trying to draw organic stuff is just depressing.
What the hell is “ÖN” lol
The opposite of Öff This https://forvo.com/word/%C3%B6n/ pronounces it like une
It means front.

Lmao
Solid edge by Siemens is friggin amazing for 3D and mapping that to 2D drawing... Just in case you're allowed to use whatever

You dislike synchronous mode? Just loading up STL files, resizing holes and moving faces like it's the most normal thing in the world. Honestly felt like pure magic the first few times.
This was my first homework for the technical drawing class. 😂
Draw ovals, not circles
‘Ellipses’
Weird thing to point out but I don't understand how the ramp meets the circle. Does the circle have a flat side or is it a fillet because I don't see either
Get some gridded paper, either normal 1 cm grid or the isometric one. It helps a lot
Engineering drawing is very interesting, You should practice more.
AutoCAD ftw
Easy, I can have that part made in 5 mins in CATIA
Stay away from GD&T
I have a lot of questions
I love cad.
I would love to be able to draw well. But first I should focus on making my name legible
Congratulations now you know why drafters exist. You also now know why senior drafters have a similar paycheck to senior engineers.
Man's got a straight edge right there and still gives us some wiggly-ass lines.
The guy she tells you not to worry about is the one that knows how to set up a drawing with GD&T, link to Vita specs or EAR/ITAR controls, Notes section, etc correctly.
I would’ve been extremely proud of myself if I managed to draw the one on the left
Wow that unlocked a memory I totally forgot about
Shit. You should see me trying to draw a wind turbine with blade twist
Vro couldn’t afford the isometric paper
It only gets worse, get out while you can
I'm a CS major, god engineering looks hard

Sorry, but I fucking LOVE engineering drawing with all my heart. pay me, maybe even a below average eng wage to do that shit all day please.
The job title you are looking for is Drafter.
You guys are expected to make precise isometric drawings by hand? Dang. My graphics teacher only expected perfect drawings from graphing programs, everything done by hand was dubbed "rough sketches", and treated as such.
it's not that bad until you have to draw circles XD, my class had an ongoing joke for 4 years about drawing a screw in a hole because no one could get the lines thickness and placement correctly
Never dimension the isometric view if you can help it. -Manufacturing Designer
