CheckerHater - If the big flat surface was a datum, surely it would only control the perpendicularity of the cutout and the 4 holes. Would that be necessary for this part? Taking the thickness of the sheet and the position/size tolerances of the holes into consideration.
I have attached the...
JNieman - Thanks for your response,
Datums C and D are intended to be the centre planes of the cutout feature, I think the Datum indicators should of been attached to the dimension line to show this, not to the extension line - I've quickly changed this and attached a small image to clarify...
I have re-worked the drawing, and applied what I think I currently understand of Geo Tolerancing. If you guys could take a look again, scrutinize and criticize it as much as possible, and let me know i'd really appreciate it.
There's a few other changes to the drawing compared to the original...
Thanks all of you for your comments, its given me an answer to my reason for posting this which was 'So I can see if i'm on the right lines and have actually grasped the subject at all!'
Rather than spending hours going back and forth answering and asking questions about a drawing I already...
I recently went through the ISO Geometrical Tolerancing course on the Engineers Edge site, I have basic understanding of most of the terms but applying it to a real life scenario is a different ball game.
I've attached a drawing I did of a Sheet metal door for a vehicle tool locker, when fully...
