I think I'm not understanding something fundamental about basic dimensions. See attached drawing.
I've put in basic dimensions for the holes. I'm happy with that.
I've used basic dimns for the slots. I realise that this probably isn't correct, but I'm treating the slots as 2 holes that are 'joined' together. By rights I should probably use the surface profile callout. Would be interested to hear peoples thoughts on this.
Should I use basic dimensions for the square cutouts?
Why can't I use basic dimensions for the outer profile of the part?
I think what I'm not understanding is the 'features of size' rule. I don't really understand why I use basic dimensions for the position of a hole, but not for the outer profile of the part.
Any help much appreciated. Thanks.
