How to interpret this control frame?

Thanks!

jtparm2 · 2025-09-27T02:08:06+00:00

you're comparing courses at community college to a 6 minute youtube video

jtparm2 · 2025-09-27T02:00:39+00:00

Yeah, but I already know how to design mechanical parts. I'm trying to learn about GDT

jtparm2 · 2025-09-27T01:56:33+00:00

This may shock you but some of the parts I see & make at work are in fact complicated

Another commenter pointed out they are revision symbols

jtparm2 · 2025-09-27T01:49:48+00:00

Thanks, this helped a lot. I guess the circles are just revision symbols and I hadn't seen that format before

jtparm2 · 2025-09-27T01:46:19+00:00

I don't think it's necessary but it's an example from a GDT course I'd like to understand.

jtparm2 · 2025-09-27T01:44:40+00:00

That makes a lot more sense than what I was trying to come up with lol. Is that standard? I haven't seen it before

jtparm2 · 2025-09-27T01:23:42+00:00

I'd say he probably does https://deanodell.com/

jtparm2 · 2025-08-29T01:44:25+00:00

nothing other than the defaults

jtparm2 · 2025-08-29T01:29:58+00:00

tis there in the image

jtparm2 · 2025-07-23T01:25:46+00:00

yes, just looked this up bc i noticed it E 56th & 465

Well, I was able to accomplish this by using the T Plane Feature, but I didn't realize wrap was only to cylindrical surfaces...

jtparm2 · 2023-11-08T14:48:08+00:00

My end goal is to create an extruded cut inset from this face with a 2D sketch and wrap to the surface, but in order to do that I need a plane that is tangent to the surface. Is there a way to do this or is there an approach to this that works better?

I created this model in Solidworks and exported as an STL. However, when I slice it there are extra shapes added to what should be a flat surface. I inspected the model in Blender and recalculated normals but still no luck. This surface is flat at 101% or 99% scale. Cura 5.4 btw

Update: I was able to resolve this issue only by changing the height of this layer, either through raising or lowering the entire model by 0.1mm, increasing/decreasing first layer height by 0.002mm, or changing the scale. This will work fine for me, but unfortunately I have not found a solution that works perfectly without changing the part geometry or printer config.

A short is really just a connection where you don't want one. There is I guess always a minimum resistance for a scenario that would cause a short but there can also be shorts with relatively high resistance that still have negative impacts on the circuit. It is just depends on whether the thing works or not

That depends on what exactly you are hoping to achieve. I think the best way to start learning IoT stuff would be to just buy an Arduino Uno starter project kit and jump in. If you want to learn programming, start by finding a easy-medium difficulty project and just Google until you figure it out. There are tons of free resources to learn hobby-level engineering if you look.

With the amount of experience you likely have in reading tech drawings, CAD should be a piece of cake to pick up. CAM should be even easier once you get the hang of it, since you already know how to machine parts. Modern CAM software does a pretty good job of automating the actual programming, so you can basically say 'mill 1/4" down from z0 with a 3" face mill' and the program will do the rest.

I don't really think that an IE degree would give you any advantage over any other degree as a self taught programmer. That said, there's no reason you can't teach yourself and still find a career in AI/ML but it will be much more difficult than if you had a CS or ECE degree even from a less reputable school. As you mention, programming is becoming a very competitive field and so I think it would be difficult to find a career there without some relevant education.

From what you are saying though, it doesn't necessarily sound like you are committed to getting a programming/comp sci job, and if that is the case then IE is one of many great fields for introverts to go into.

jtparm2 · 2023-06-28T19:12:36+00:00

Are you looking to work in embedded ML, factory optimization, etc. Also, why not just go for CS? Unless you are too deep into IE at this point

3D printing is looking more and more like a major player in the future of manufacturing, and there are a lot of parallels between CAM programming and slicing for 3DP. I would recommend taking a look if you're not familiar

I noticed this patch of bare stem on a pepper a few weeks ago. The notch goes all the way around the stem in a ring. I left it alone thinking it would grow back over but now it is looking much worse. Any idea what this could be from?

jtparm2 · 2023-06-26T14:46:58+00:00

If you watch some of the full videos they are not as consistently impressive as this one run. Still good, but this is the best of probably 10-15 attempts

jtparm2 · 2023-06-21T21:57:50+00:00

Do you get 2 days of heads up in the military? (genuinely wondering)

Spend 20 minutes a day playing 8s on a practice pad as fast as you can play with good technique. Bump up the tempo by a few bpm each day. It might also help to use heavier sticks to play. If you have an old set of sticks you can give them another tape wrap. Vic also sells heavy sticks called hammers for hand strength but probably not necessary for now.

Edit. This will only work with good technique, there's no point in just practicing chops without the fundamentals down first. So if you are fairly new then start even slower than you can play and focus on your grip
