Engineer 2 here. Just a small point; calculating the size of a "missing" dimension from other information on the drawing is fine. The examples shown were excellent. However, the comments regarding "scale" require some clarification. The scale in the title box is for indication only and provides an idea of how big or small the finished part is. What it is not intended for, at least on my drawings, is for anyone using the drawing to work out a missing dimension by measuring it and using the scale. In fact, a lot of drawings have "DO NOT SCALE" on them. If a dimension is missing and it can not be worked out from the information on the drawing, send the drawing back to the Engineer or company you are making it for.

I'm a tad scared of this aspect of welding. I'm about to graduate from my community college, and my teacher has set me up with an interview/weld test. We went over blueprints and weld symbols 3 semesters ago. While I wouldn't say my teachers instruction's weren't clear, it's been a solid minute since I've had to read them in any capacity. I've never built anything off of a blueprint and outside of a classroom setting, I've never read one alone. This video was helpful, but also intimidating. My teacher isn't to blame though. He isn't in charge of the welding program classes. He said he would've liked to have had a dedicated class to just blueprints, weld symbols, and fabricating from blueprints. The one to blame is the instructor at another campus in charge of the program classes. Would've much preferred a blueprint class to a robotics class(It was a joke of one anyway). I hope the people who are interviewing me are understanding that I've never worked a welding/fabrication job before.

Or Could 2"4" also be 4" start measurement from end of piece and go in one direct?

Your comment "that the drawing was not to scale" is incorrect, it is to a scale, and if as you said it was 1:2, something in real dimension that was to be 8" would be drawn at 4" or 1/2. When something is "not to scale", it means exactly that, so you cannot measure off the drawing, so a piece may be 8" long x 6" wide, but on the drawing could be drawn in different ratios, so 4 1/2" long x 4" wide, that is NOT TO SCALE.

@dennisleadbetter7721 3 жыл бұрын

@@rotam8680 that's basically what I said. A drawing that is "not to scale" technically is not to a "consistent scale". But individual parts (lines) would be to a scale, even if full size, that would be 1:1. An example, if you had a rectangular plate, that had true dimensions of 10 units long and 6 units wide, if it was drawn at 5 units x 3 units it's at a consistent scale of 1:2. If that same plate was drawn at 4 units x 2 units, then the scale for the 10 unit side is 1:2.5 and for the 6 unit side is 1:3. While individual items are to a scale, it's not a consistent scale, therefore it's not to scale.

Why not 1. Sandblast all the millscale off of the original plate before it's cut on the CNC machine, and 2. Program the angles of the cuts at 45° into the CNC machine before cutting the part? You wouldn't have to even look at the angle grinder and the angles would be perfect every time, no prep required, the parts could just be taken directly from the CNC machine to welding. It would save hours of prep and countless angle grinder discs.
