1.4b-Placing of Dimension Systems in Engineering Drawing: Aligned and Unidirectional Systems

This video teaches two systems of placing dimensions in engineering drawing: Aligned System and Unidirectional System. You should learn both systems but use only one in a drawing. One drawing must follow either Aligned or Unidirectional system of placing dimensions. Dimensioning also requires good lettering to write the dimensions. Remember, you should only write the dimension in millimeter. No need to write the word "mm" or "millimeter", just the number. It is understood that the dimensions are in millimeters. Other important tips, never ever dimension more than what is just necessary and one dimension of the object should never be dimensioned twice, for example in two different views. Proper spacing between two dimension lines, size of the numbers relative to the size of the drawing are to be practiced. Also, practice how to dimension a diameter using leader line.

The video is very helpful to some of us still studying..thank you so much for your wonderful help

[@BobbyWillie]

Thank you Sir for the incredible video it is very helpful for as a student

Great work continue we support you

Question: There is a good reason why we shouldn't place dimensions directly on the drawing itself. This is to avoid ___. A. Super dimentioning B. Overcrowding dimensioning C. Inaccurate dimensioning D. Aligned dimensioning Pls. reply ASAP for my homework. Thanks

[@1styearengineeringdrawing182]

Likely B. 👍✔

Sir Nice Explanation 👌

Sir my question is what are that 1:1,2:1,1:2 plz reply sir

[@1styearengineeringdrawing182]

These represent scales. 1:1 means the lines have length which is same as the actual length in the component. 2:1 means all the lengths in the drawing are half of the actual length in the component. kzbin.info/www/bejne/favInnemjramaLc

[@prasadprasad3552]

Sir say about methods of dimensioning sir like chain,parallel, progressive,combined,coordinate dimensioning do video about that sir please

[@1styearengineeringdrawing182]

Thanks for the suggestions. The dimensioning explained in this video is the necessary part for your first year in any technical education. 👍

[@harshithtechy1300]

Sir will u tell about arrow marks in 1/3 aa

[@1styearengineeringdrawing182]

kindly clarify your question.✔

[@sadityadatta9418]

What is the diameter of the circle of aligned system?

[@1styearengineeringdrawing182]

It is 20 mm for both cases👍. Sorry for the poor video quality.

[@zareenakouser3819]

Sir what is that scale name

[@1styearengineeringdrawing182]

Rolling ruler

[@VickyMSyiem]

Sir we have to draw only Aligned system and unidirectional system .

[@1styearengineeringdrawing182]

Either Aligned system or Unidirectional system. Do not mix them in drawing. There is no other system of dimensioning.✔

[@dharanidaggupati9510]

Sir plz tell 3sem drawing for civil engineering in diploma.

[@1styearengineeringdrawing182]

only for 1st year here.
