are you asking about multiple parts on the same sheet? under the layout tab, there is a drawing models icon, you can select the other parts you want on the drawing. this is not good practice because multiple parts in the same drawing unless its an assembly drawing. but then you must set the model you want as current to place your views of that part.
How did I get here? Sorry, more mistakes done than clicks that made sens. 😪 I don't want to be rude. Default scale should contol default scale. View scale, like Detail, controls the scale of one view. Change view Display in one step. Much easier and of course faster! Modelling: please User RMB this is a presentation of your skills! Dimensioning of first Revolve Feature: use diameter dimensions. The extrude feature is a Dimension. Should be through all. Use hole Feature for hole! Table should show parameters not only text. I was so shocked, i had to write down this comment. Hope this helps a bit.
painful to watch you stumble around in the two of your offerings I watched. Practice a few times before you record instead of wildly clicking anything that moves.
