Orthographic Projection 7: 1st and 3rd angle

[@JulioSoto1685]

I've spent quite some time today looking for a clear explanation of these differences. This is the best by far! Fantastic video.

[@rifat6049]

this kind of varification in comments saves a lot of our time, thank you

[@Bali25]

Agreed. Really clear explanation.

[@mercyisaac5401]

4 years later and this saved my life. thanks Thomas!!

[@jonahadjeiannan7348]

Been searching for an accurate explanation for a century and you proved to be a pro, I can finally rest☄️

[@shaheerulhaq474]

THE best video on orthographic projects I've EVER come across.

[@swingymcswing]

This is the best explanation I've EVER seen !! Thank you, Mr. Sheppard

[@ahmed-al-kabirnadim7477]

This video may not have much view but know that there is someone out there who has been helped immensely by this video. I search so many videos and was sooo confused and none of them were clear and concise as this was. Also great animation.Thank you so much for this!

[@MuhammadAhmad-pk7nv]

Excellent explanation of 1st & 3rd angle of projection. Thank you very much for this resource !! Clearly, it is indeed a lot of hard work someone has put into this video, everything is so perfect and balanced.

[@thecustomadventures7719]

I've been looking so long for a good explanation! This is wonderful and very easy to comprehend. Thank you very much!

[@updownleftrightish]

Great Video better than I could explain it will use this for my class.

[@ClayMangiameli]

I watched at least 10 different videos all of which weren't that clear, but this is by far the most helpful with really good animations to demonstrate

[@everlastingmusic6539]

The best explanation you can ever find👍

[@Manikanth_Kolapalli]

Wow, I have been bit confused till today about the projections, But your crystal clear explanation given the clarity and confidence. Thank you, We are expecting more designing videos from you like this...

[@tonywilliams9600]

Clear, concise....a benchmark in getting a point across. Really appreciate your approach. Thanks!

[@rajarajans2515]

[@gamagehemaratne9300]

Best, clear Explanation

[@Drie237]

Quite complex but very helpful so thank you.

[@raditya5663]

thank you it is make easy for me to explain this to my juniors about the difference like reason "why it is reversed between the prjection"

[@owinyinnocent6535]

Best explanation ever!

[@juancarloslucena9284]

best video about this topic ever! Honestly LOL

[@refiloeleanyatheko9281]

This is definitely my saving grace. Thank you.

[@wallygoots]

About the different conventions, is it accurate to think of 1st angle as rotating the figure toward the left to see the right side, right to see the left side and down to see the top while 3rd angle is more like moving the "camera angle" while the shape stays static?

[@thomassheppard5369]

Hi Seth, the answer to your questions is yes and no. Yes in so far as you can visualise the orthographic views as either rotations or as different camera viewpoints (I personally like to visualise a bundle of security monitors stacked ontop of each other). No in so far as both analogies can be used for either 1st or 3rd angle. If you take the monitor idea, you could arrange the monitors so that the monitor for the plan view is stacked on top of the front view monitor (resulting in a 3rd angle convention) or below it (resulting in a 1st angle convention) likewise the side view monitors could be swooped around to fit either convention. The same can be said for the hinging analogy. If you imagine the object stuck to a trapdoor which can hinge either from the front or back. If the trapdoor hinges from the back the top will tip down and end up facing you (resulting in a 1st angle convention). If the trapdoor hinges from the front, the underside of the object will kick out and end up facing you (a 3rd angle convention). It all depends on the position of the hinge, in front of the box for 3rd angle and behind the box for 1st angle.

[@wallygoots]

@@thomassheppard5369 This is awesome! Very well worded. I am investigating this because I want to give my Geometry students some industry perspective on orthography. I do find 3rd angle easier to visualize. I think it's what I'm accustomed to.

[@abson1408]

thanks man this video means a lot to me !!!

[@blessed8068]

Quality Content.

[@diegoalvarezalzate5775]

Thank you so much... Finally I got it!!!

[@perfectionframing7067]

Brilliant explination!

[@kunalchangoiwala7474]

Great work! Could you please tell me what software did you use for making this video?

[@thomassheppard5369]

Hi Kunal, thanks for the comment. All the animations were done in Microsoft PowerPoint. I draw the 3d objects in solidworks and save the basic 3d lines to a dwg file which I open in autodesks autocad to tidy up. I then export them as a .wmf file into PowerPoint where I ungroup the lines. This has the effect of converting them to something PowerPoint can read and animate. All the rendering and colour is added in PowerPoint.

[@thomassheppard5369]

To do go through the process I have a video on my channel kzbin.info/www/bejne/fqCaoKCbr75rbtU which should help. I know this is probably not the easiest or most correct way to animate things but I don't have any training in animation and this approach allows me to use the PowerPoint as my class presentations where I can click along and explain them live. Hope this helps

[@arturzych138]

Beautiful

[@NorthernItaly-gm5nl]

[@martybadboy]

9:25 Top view: is there a reason red and blue reversed?

[@thomassheppard5369]

There is a reason, but unfortunately its down to my own human error, the red and blue should be switched in the third angle version. Well spotted.

[@dineshpalanisamy7389]

Good sir

[@rifat6049]

thank you

[@domytylla8170]

Thanks 😊👍

[@kamleshchauhan5562]

What actually the planner reference in 3rd angle mean?

[@thomassheppard5369]

KAMLESH CHAUHAN I have a video that goes through explaining the 3rd angle symbol which might help kzbin.info/www/bejne/gpyXY3iDqsiUhZo

[@suniltanwar7625]
