BLUEPRINT READING PART 1, Marc L'Ecuyer

[@jimmilne19]

The bowl method is absolutely the best I have seen to describe 3rd and 1st angle projections, and, I saw it here first. Thanks for an illustrative and easy to understand "I'll remember it forever now" demonstration. I was just about to dose off ( I am viewing at the end of a blueprint reading day) when I heard my name called out, which brought me to attention. A good teacher can even call to consciousness even the most sleepy student! hehe It is seldom that the symbols for which projection is displayed is actually put on the drawings I see although one usually can figure it out from the drawings. It is however, nice to see a drawing made by a draftsman, complete and professional. A super video and I look forward to the next in the series. As always, thankful and appreciative, jim (still) in Greenland.

[@THATLAZYMACHINIST]

Hi Jim, I have received many comments on the bowl method for explaining projections and I must admit that I don't remember if I learnt it from someone or if I made it up? If I did make it up, I just might be a little smarter than I thought? If anyone out there (other than my former students) has ever herd of the bowl method, please let me know, it could help to reduce the swelling of my ego! Thanks for watching Jim and until we write again, Marc L'Ecuyer

Taking my blueprint reading class today for a 23$/hr job! Im stoked! Thanks for the help sir.

[@yvetteehrlich6436]

I'm starting a career that requires knowledge of blueprint reading. It's been a while since I have needed these skills and was an amazing refresher to the lines and views! The illustration for the first and third angle projections was simple, effective and easy to remember. I look forward to seeing your other instructional videos! Thank you for taking the time to do this for us in need!

[@JohnBoyJoy]

I'm starting one too. how are you doing now?

[@connectnetworks213]

I've taken the blueprint class and I'd like to say that I love your videos, you are right on and your explanations are comprehensively in depth.

[@andrewhearington7566]

I have a new employee at work that needs training and I just came across your video today. You are awesome and you do a great job explaining. These are the perfect videos to teach a beginner. I appreciate you. =)

[@vivekmodi1859]

I never understood difference between 1st and 3rd angle projection so clearly as now, this is by far the best method that i have come across. Thank you Sir for sharing your knowledge!

[@Kiereze]

First year machinist student here, really appreciate the video. Helped me on my homework about how lines from one view have a matching line on another. So for example "Line 34 in the side view is what line in the top view?" I was pretty lost until you went over what the lines look like and what they represent. Thanks, I'll be watching your other videos too!

[@nodozzz1]

Thank you for taking the time to make these videos. You're a very thorough teacher.

I work at Snap on and I’m about to take a test in the morning for a CNC Set up position. These videos have been a HUGE help and I’d just like to say thank you.

[@Worksengineer]

Excellent explanation Marc. I learnt this over 40 years ago, and you're bowl method is a good way of explaining it, we here taught the box method. In the early seventies we were taught both 1st and 3rd angle, Here in the UK we are 3rd angle and I believe we have been this way since the late 1950's

[@brianadams6961]

Marc, I enjoyed all four info videos on Blue Print Reading. Engineering drawings is what there being called today. So I hear! I was hoping to see more. This time explaining how to find missing dimensions, and the process of the mathematical formulas to discover there value. For example, on center, and off center holes equally spaced holes, bolt circles Find a length by using a radius. Find a length using trigonometry. Also touching base on sides that represent each other. More shops are going with planning instead of floor prints. We are suffering out here from the dumbing down we are being dealt. Thanks Marc, I love what you’re doing. Thanks for your help.

[@mhd230289]

[@michaelowusu4806]

Great teaching from basics! Thanks a lot. This is immensely helpful.

[@viperspec]

I thank you for all your videos. I am almost at the age of retirement and want to start building a home machine shop. As an aircraft mechanic, I've always admired those who worked in the machine shops and have always wanted to have my own as a hobby. By the way, the "First Angle" view makes more sense to me on a drawing. It represents, to me, like I just pushed the part from its top edge and it fell to that position. If I push the top over to the left, it falls the way the drawing represents it. I don't know, it seems easier for my simple mind. Once again, thank you for being a great instructor and teaching with the passion you do!!

[@shaon56]

The way you described first and third angle projection was very good..I really got a good understanding, thanks!

[@JonDingle]

As an unskilled man, I can safely say to anyone that you can learn so much from these videos. Really interesting stuff, thanks!

Marc, this was exactly what I needed to see. I just made a print today and as I drew my lines, I asked myself if they were correct and I questioned if I using the "correct" lines. I'm eagerly awaiting the other parts. Thank you so much for taking the time to share this crucial knowledge and in a way that's so easiest understood/digested. You're a great Teacher.

Good Teacher. Not only you know the subject but your teaching method and warm emotional appeal is tops. Doing it for free is great but the value offered even if it was at cost would be attractive. Hopefully youtube will payback a little with the number of hits you get. Yes not everything needs to be done for money but the shear fun of it...ain't it why we is machinists in training anywayz? Well done. I vote best of youtube for this series!!!

Blueprints for vehicle frames are self explanatory really. I didn't know the name of the lines, but all the welds are done in these type of lines as well. Same meaning. I'm looking into going to a millwright job here soon and I need to know all of this as well.

Therefore, I relearn it and noticed that something is wrong. By the way, the new thing for me was a phantom line. I think I've seen it after graduating but never focused as much and for sure we did not study them in our Russia.

@@nikolaisergeichuk6415 in Russia, you use the metric system, correct? I am an industrial maintenace mechanic in the united states. We use both american standard measurment as well as metric; metric mainly to work on 'forign machines'. What confused me was the terms the instructor uses are different than the terms used in the States.

[@nikolaisergeichuk6415]

@@flammenwerfer9645 Now I see. Just imagine my struggles then. I can't find any resources for learning blueprint translation. The main problem is abbreviations. It seems to me that foreign standards allow far more freedom for drawing layout and appearance. I am confused so much that I don't know what to start with and watch such videos. Anyways, I still think I can be more competitive in that field as I have a degree in engineering.

Your "Bowl Technique" is brilliant. It made clear several concepts for me.

Marc, Thank you for sharing your time and tallent. The bowl method is great. The best explanation I have ever seen. Thank you

[@jobsucks]

The analogy using the wall for first (1st) angle projection was confusing. But once you demonstrate using the bowl it was more clear visually. I think of 1st angle projection as if you were physical holding the part and you have to rotate the part to see each side/face. For example, think of the simple shape like the rectangular brick or the Rubik’s cube. Hold it so one side is facing you. Denote that face as the front view. Now rotate it up to see the bottom side of the brick/cube. That view would now be draw above the front view even though it’s the bottom face of the part. Now, return to the front face again. This time rotate the brick/cube down to see the top side/face. This top view is drawn below the front view. Return to the front face/side again. Now rotate the cube the your left to look at the right side/face. This right side is now drawn to the left of the front view. For third (3rd) angle projection. Imagine the same simple shape of a brick/cube. But this time the brick is fixed in position. You cannot rotate, pivot, or turn it. To look at each side/face you need to shift your POV. Imagine it as a box shape with flaps/lips. Each flaps is hinge to the primary view (front). To see top side lift the top flap. That view is drawn above the front view. To see the right side you pull right flap towards you. That is drawn on the right side. In summary, 1st angle projection is view from one POV. The first person. You rotate the part to see each side. The POV is fixed. 3rd angle projection is view from multiple POV. most commonly 2-3. The part is fix but the POV changes. (Hope my summary is more clear than my detailed explanation.)
