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!
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.
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...
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.
To do go through the process I have a video on my channel ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ho7omezY88s.html 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
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?
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.
@@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.
KAMLESH CHAUHAN I have a video that goes through explaining the 3rd angle symbol which might help ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Lk42EMucaO8.html
