In video sketch, 30 value is given for this dimension but in the drawing it is 32.
I wish to know whether incorrect value is given or value of the dimension is determine by below symbol.
The incorrect value is given somewhere. I would personally go by the actual drawing not what the video did since it could have easily been a mistake on the videos part.. That symbol is a surface finish....as explained in your previous thread.
This is a Surface Finish Symbol
