Haha, dankie! die stem is ook bietjie anders in hierdie video.

Good day, It is only available in hard copy, in South Africa. We use it for our course that we present at the University of Pretoria. Here is a link: www.wizebooks.co.za/get/9781119923329-custom-graphical-communications

This class is for first year, first term engineering students at the University of Pretoria, South Africa

thank you sir .. I'm Iraqi citizen and my language in English is weak .I hope you can understand My writing....I had been taken engineering drawing before thirty years in baghdad university college of engineering and my drawing sheets were losted since 1992 when I was graduated and I remember that we were study in second year of college that kind of engineering drawing

@@عليعلي-ط9ج8ظ I understand it perfectly, it is good enough :) Wow, that is quite a while ago. It is good to see that you still have interest in that field. Have a blessed day. Kind regards from South Africa

The bottom view is a partial bottom view because we use it to only show the bottom plane. The arc in the top is shown in a separate partial view. This is the simplest way to show the features.

The hidden detail in this example is used to show that the vertical holes go all the way through, which is not visible by looking at the other views. The horisontal hidden detail line shown in the right view is just for clarity

Thank you for the kind comment, it is appreciated. Kind regards R Meeser :)

Good day, Thank you for the comment. She does not work with us directly anymore, and all the videos that she made have been uploaded already. Kind regards

@@riaanmeeser4755 ok sir can you tell me where did she works now?which channel she works with it ?or any address belonged to her work?I'm mechanical engineer and I had been lost my drawing sheets so I don't remember my drawings which I plotted in the college. University of baghdad and I needed it so much in my work in maintenance of pumps in workshops of the company. Your lectures are very useful sir it had been returned my memory in engineering drawing but that mrs had been explained ditticult assembly drawings .please sir can you also communicate with her and tell her our respect and our greetings to her 🙏 💜 ❤. Thank you sir for your forgiveness to wasting your time God bless you 😊

The videos posted here were mainly as additional material for our students who are primarily taught in class by ourselves at the University of Pretoria, South Africa, so that is why the examples here are somewhat limited. We also can not post a video for all of our assignments as that would mean that we can not use those for assessment purposes in future. The person who made these videos is still with our university, but has moved to a different department, so she is no longer able to make these types of videos. I will send her your compliments when I see her again :) Kindest regards

@@riaanmeeser4755 thank you very much sir and I thank God to give the opportunity to talk with you sir .please sir don't forget to tell my greetings to our genius Mrs professor..

It might be due to the cross section sketch being open or not a flat sketch, or it can be due to the profile intersecting itself. It can also happen if the profile and the path lie in the same plane, in which case no volume will be created when sweeping, causing an error. Use more basic sketches for profile and path, and make sure they are not in the same plane and see if it helps.

These lectures were presented to first year engineering students at the University of Pretoria, South Africa. Dr. Smith, who did these videos, has moved to a different department
