Basic and DUAL dimensions

Basic and DUAL dimensions

Basic and DUAL dimensions

(OP)
We are using Solidworks Office Pro 2007, SP4.0.

Another bit of help....

I have my dimenions and notes set the the proper font that our company uses.  My situation is, a few drawings we are doing have DUAL dimensioning.  

Seems when you do use dual dimension and make the dimension BASIC, the outline box looks pretty tight.  First is there a way to make this box a bit BIGGER.  Second, with dual dimensions, is there a setting to place the dimensions on top of each other, rather then SIDE by SIDE?

Thanks in advance
 

RE: Basic and DUAL dimensions

designmr,

   I show dual dimensions on reference drawings, i.e. the sort of drawings that do not have basic dimensions.  

   On a fabrication drawing, your dimensions are an accept/reject specification.  Dual dimensions rarely work out exactly, so they are ambiguous.  Don't use them.

   Does this solve your problem?  smile

Drawoh, I wish it was that easy.  These are old Autocad drawings converted and the higher up here do not want to change.  
I figured out how to put the DUAL dimension on top of each other that is in OPTIONS.
Now I need to figure out how to make the BASIC block bigger, without changing font size...

RE: Basic and DUAL dimensions

Tools>Options>Document Properties>Detailing... you should be able to select where the Dual Dims are placed.

I agree with Drawoh, Dual Dims should only be used on drawings that are for customer shown-n-tell, not for manufacturing.

RE: Basic and DUAL dimensions

I would go one step further to day that dual dimensions are not allowed in the scenerio you described.  Since the translated number is not absolutely the same to the number in the primary units, to have both as basic would be providing two different (though similar) numbers as your basic spec.  This is violation of AMSE Y14.5 which says each specification should have only one meaning.

All well taking advance, unfortunately being on release documents.  Our bosses do not want to change... So we need to make the dimensions look presentable.  

I just tried enlarging the font, funny things is the BASIC box, does not get larger.  So my search is on..

RE: Basic and DUAL dimensions

The only way I know to make the box larger (wider) is with note text. It can't be changed with dimensions.

ctopher, but then I would lose the Parametric, I believe.
