Question

For Discussion: Should SCALE be in a drawings titleblock?

Happy Friday,


This is more of an academic discussion starter thana problem. We are looking at updating our engineering formats and the question of whether to eliminate the SCALE field came up. Given the approaching model-onlystate of ASME Y14.41-2003, is the information necessary to have in a drawing?


Have at it.


Thanks,
WindchillAdministrator

Jeff,
You can’t just erase the scale, it’ll also erase the parametric name as well.

Our vendors frequently use 2D DXF and IGES files for wire burning. Not have a scale note is asking for trouble. In fact, we put a HUGE scale note right across the entire print on export to keep from getting burned (pun intended).

I'm old school and I think that it is  dry practical to have the scale on a drawing. Of course we want to also place a note on the drawing telling our audience not to scale the drawing.

That's a very interesting reference to the shipbuilding industry

I would still push the burden of "built to print" on the vendor regardless of whether an electronic file was sent. I have provide flat patterns of formed steel parts to vendors on MANY occasions. I always add the disclaimer that the flat pattern is for reference only and that the drawing is the legal document providing the requirements of the contract. There are too many variables in manufacturing that can't be taken in to account on an engineering print and especially on an electronic file. Even with in-house manufacturing, you don't always know how something will be built. The metric to English conversion is one problem that used to come up frequently.

If at all possible, I never use a dxf or iges without verifying the critical dimensions. There have been times when I have received generic product files for something that I was expecting specific product information on.

The REAL  problem lies in the new school philosophy of not fully detailing or sloppily detailing a drawing.

All,

Everyone has great points, but as we move forward into the Model Based Environment there will be no measuring off of a drawing and no need for a SCALE. We should be moving forward in our industries as technology advances.

I have to disagree. In our world “Shall” is an absolute requirement. If it is optional we say should or may.

I’ve been hearing about doing away with drawings since 1992, when I was told that Unigraphics II came out initially without a drafting package. I have had parts made without drawings since I started on Pro/E in 1992 but to document the design still needed drawings. While I agree with you that it is now POSSIBLE to document the solid model (although still not platform independent until STEP AP242 is widely supported), it is still not the most overall efficient method. I say that understanding that if you have control over the entire production cycle including quality, it may be more efficient but we simply aren’t there.
