I began learning AutoChad2018 a day or few ago. I dont understand what I'm doing wrong. I can't seem to offset in z axis on the triangle. I'm trying offset .5 down on left and right lines and offset up on z axis, but all of them are only allowing me to offset in y axis.
I don't get it. Any help anyone?

This is what I'm trying to do, but when I do it, all the guy does is "offset by typing 'O' for offset, .5, drag down"
and that doesn't work for me when in "Front" view.

i fairly believe you are on the wrong board
It's been a while since I did anything in AutoCAD, but, as I recall, you have to switch into 3D mode first.
What board do I go to?
What's the 3D part because it was working fine, did two of the lines, but the (what seemed to be magically..) it stopped working and I can't seem to figure out the "put it in 3d mode"
also. thank you guys. I appreciate any help, or having even responded
They're going to say /3/, but they only know applications like blender and maya, not autocad/solidworks/inventor/etc.
There's a keyboard shortcut to switch between them, but I can't remember what it is. Is there a thing that says "Default drafting" or something in the top left corner? Click on that.
What are you trying to draw? I'm just an amateur, but I prefer Inventor over AutoCAD, since it's 3D and you can export 2D faces to AutoCAD if necessary.

Im pretty much on this step. And i'm new myself, started two days ago or so. I'd say I understand most of it, as shown and another tutorial. I just can't seem to offset on z axis, i tried for an hour or two, googling, messing around, nothing. Finally decided to post here, worst case.
Not sure what you could be talking about besides the bottom right saying
Drafting + Annotation.
3D basics
3D modeling
Each of them don't really do anything (that is affecting anything from what I can see.
The last version of AutoCAD I used is 2014, so things might have changed, but there was a drop-down menu where you could select between different control schemes, with 3D being one of them. Another example was the isometric controls, so you could quickly draw in 2D.
Alternatively, you could try offsetting by typing it manually. If you feed it 3 dimensions, the 3rd one will be the Z offset.
Autocad is the most botnet of the botnet. It's the worst of the worst. Stallman himself cries whenever you use it. We will not help you use that abominable piece of proprietary software that even makes you sign your designs away to autodesk.

yeah, man. I dont or see it. And trying to type in "sometimes" works.
like.. I guess its not letting me click the line, and manually doing it, did it for one line, but now it won't work on the bottom line.
also. i'm just learning "autocad" so its not like I know what's "normie" or not.. and it seems like going through a few random jobs around where i live shows "autocad" and solidworks being the most recommended. so I just downloaded those.
AutoCAD is mainly used by old companies who haven't changed how they do things since at least the early 90's. Solidworks owns the vast majority of the market and with good reason.
Also, so help me God, if you leave any blue lines in your sketches in Solidworks I will track you down and strangle you.
I haven't tried solidworks, but from the sounds of it, I should probably download that or whatever/however that works. Any advice? or any comments on how to jump into the job market with no 2/4 degree in anything?
Solidworks (and most other currently popular drafting applications) uses sketch based parametric modeling. It's a rather large change of pace from AutoCAD (for the better), but the first couple days can be a bit of a headache adjusting to it.
>Advice on joining the job market with no degree in anything
Don't? There are sooooo many different aspects to drafting that you wouldn't know and fucking up in the field can lead to deaths, even for seemingly mundane things.
I worked for a few years in the store fixture industry, for instance. Shelves, racks, cash desks, locked displays, changing rooms, etc... I was always really anal about things being super durable/safe and QC'ed to the moon and back, but not everyone else in the department shared the same mindset and we'd get into arguments over it during engineering meetings all the time (like, legit shouting matches).
One day, a fixture that was designed by the person who argued against strenuous QA/QC procedures the most came back. As soon as you walked into the office it was just sitting there in the middle of the room with one side completely covered in blood. It had this little panel on the side you could lift up like a wing and it had a steel tube on a hinge underneath that would swing down and form a leg. The problem is, the end of that tube was open and when one of the store employees where it was installed lifted the wing, a couple of their fingers were inside the opening to the tube and were chopped off as the tube swung down. I gave her the biggest "I told you so" in fucking history that day and she ended up transferring to another department (lmao, 12+ years of seniority and nepotism).
So what should I do then? Vague what do I do, but what else could there be. I also thought there are positions for entry level rather than full on, that are mostly revising and what not, rather than full building or product/part development. It seems like what you're sharing was more than "entry level."
Odds are, there's a vocational school in your area with a drafting program. I'd strongly urge you do one of those.
Take a look at the two methods of dimensioning in the attached pic. Which one would you do?
>Which one would you do?
Probably the second one? Its size doesn't blow up with increased length and it contains the same information
I would assume the second one because it gives you each detail, when the first one doesn't give you the dimensions/lengths of the spaces or anything. Or it would be more work than the second one.
I mean, 2 days of random CAD, can't say I should know it that quickly
Alright.
So, let's say that the guys in the shop could produce parts with a tolerance of ± .001" and you handed them the same part drawing twice.
The first dimension on the first drawing could come out as .599 to .601 (.600 ± .001), then the second 1.799 to 1.801 (1.800 ± .001)... and then it ends up as either 5.999 to 6.001" (6.000 ± .001) in total length.
The second part, on the other hand, could end up as .599 to .601 (.600 ± .001), and then the second dimension is 1.199 to 1.201 (1.200 ± .001), but if you measure from the start to there, you end up with (.600 ± .001) + (1.200 ± .001), which can come out to 1.798 to 1.802... by the time you get to the very end, instead of being 5.999 to 6.001, you end up with 5.993 to 6.007" in total length. The larger the part and the more features you have, the worse this gets.
Then, when you consider how things are machined, you set up a "zero" and machine everything from there, so the machinist would have to do way more math in order to machine the second one than the first one (What's .600 + 1.200 + ... - the radius of the tool and the amount I leave on for the finishing pass...?). More math is not more better.
Yeah, the first one is missing details, but it was more about the style of dimensioning, not the missing dimensions. In a real drawing, you might put "TYP" for the width of the grooves if it's a typical dimension, for instance.
>let's say that the guys in the shop could produce parts with a tolerance of ± .001"
>you end up with 5.993 to 6.007" in total length
The second diagram specifies that the width is 6.00". If they have a tolerance of 0.001, the total length has the same range as in the first diagram.
Also your example goes on about how the machinist would be accumulating errors by measuring from the previous cut instead of the origin, but then you talk about how they have to do math to convert the relative lengths to absolute lengths, which would eliminate the error accumulation.
So, let's say they cut the blank and that comes out to 6.000 ± .001, then where does the rest of the stacked tolerancing show up? Maybe you end up with the last groove being 6 thou too wide.
I'm not making this stuff up, man.

There are a lot of "best practices" when it comes to drafting and handing a machinist a shit drawing is a good way to get your tires slashed, lol.
I'm not telling you this shit to say "LMAO YOU DON'T KNOW THINGS, YOU CAN'T DO IT!", I'm telling you this so that you actually learn what you need for it to avoid getting yourself or anyone else into trouble for it.
1 - progecad can be bought outright for like 200 euros
2 - 3d is for faggots gys immediately
working directly in 2D is fine if you already know exactly what you want, but drawing unique, large assemblies is a whole lot easier when you can really visualize how it all fits together in 3D
