Question

Attributes with Units

If this answer changes depending on PartsLink, please elaborate.



I have some attributes for electrical components that are described by our Engineers in different ways. Say I use an attribute with units for resistance and capacitance. Those are defined OOTB as ohms and Farads. In the world of electronics, sometimes those discrete values are not used by default. For capacitance, a unit like μF (micro-Farad) or pF (pico-Farad). For Resistance, it might be K (1000 Ohms) or M for (1000000 ohms). This presents a problem between how the system might want to manage them and how they should best be presented to users.



I would like to eventually use classification search with PartsLink and enter ranges for these values. If the units are not the same, I would think that would fall apart no? However, I would like to spare the user from looking at values such as 1x10^6 ohms (1M) or 4.70 X10^-10 F (470pF). Do I have to give up and use Strings?

I believe you are talking about Unit of Measure for quantity. I'm referring to part attributes that are Real Number with Units.

I may not entirely understand what you're getting at, but I setup a UOM family on our system, so there's families like each, length, weight, etc. Basically, when the user creates the part, the base unit selected determines the UOM "family". Then when the user adds the part to a BOM the only UOMs they can use are those in the base unit family. So, if the base part is IN (length), they can't set the UOM to LB (weight) on the BOM.


It sounds like this is sort of along the lines of what you are trying to do.

Patrick can you elaborate a bit more on this? We are working on PartsLink right now and the two largets complaints are around the units, 1st search results, 2nd data entry.


1) Is it a customization to get Windchill to present the UOM with the correct prefix, instead of just the Base Unit?


2) Can a user when enter a value specify a prefix like KOhm instead of Ohm, etc...


Thx,
Steve D,
