is it okay to dimension section views.

 

[ewh]

While the standard is aimed at 3D model definition, drawings are still allowed. There are also changes to GD&T that are to be included in the next release of Y14.5. If your restricted to Y14.5, then you will have to refer to ASME Y14.3 to determine if dimensioned iso views are allowed. Unfortunately I don't yet have a copy of that standard.

aardvarkdw,
Only 3 views. But, doesn't matter anyway, all views are the same.

Sorry I wasn't more clear. I was curious to whether or not he was "requiring" 3 views. I could just imagine all the scratching of heads and attempts at making three "different" views of a sphere. In fact I can't help imagining Lucile Ball...

 

[ctopher]

Yes, he required only 3 views.

ASME Y14.3 is no help. It is a carry over from the drafting board days and assumes people know better than to dimension ISO's.

ctopher,

Out of interest could one of those views be an iso?;-)

 

[ctopher]

No, An iso could be too difficult.

[ewh]

They could use descriptive geometry on it!

 

[ctopher]

ewh,
Now, to a lot of new drafters, that's getting into too much science and physics.

[ewh]

Yeah, that went the way of the slide rule.

 

[palecactus]

IS IT OKAY TO UP THE SCALE IN SOME VIEWS OF A DRAWING OR DO THEY ALL HVE TO BE THE SAME SCALE? THANKS

 

[ewh]

As long as it is noted, yes.

 

[wgchere]

yOU CAN UP THE SCALE IN VIEWS OF A DRAWING, BUT THE SCALE OF THE SHEET (THE SCALE LISTED IN THE TITLE BLOCK) MUST BE THE SAME ON ALL SHEETS.

iT'S THE RULE.

 

[ctopher]

palecactus,
CHeck out the ASME standards. There are certain scales to use. You do not want to use for example 1.25:1 or 23:1.

palecactus,

ctophers advice about the standards would go for a couple of the questions you've asked.

I'm sure most of us are more than happy to answer questions but if you get a chance to look at the standards that will answer not just your immediate question but maybe tomorrows as well.
