Quick Questions :

 

I am selecting a quick measure of weight under measure bodies , i select one body and get

Weight                          =   33.22022386745 lbf

 

What units are 1bf? (I just want to see lbs)

Where is the best place to change the density to another material like wood? (can i do this on the fly or must use customer defaults and log out and in again )

Can I set up a cell in a PMI Table to have the attribute of the weight, I have seen some info for drafting out there?

I assume if i have multi bodies I would just tally up the cells for total weight?

 

thanks

 

You can control how the callout values in the NX Parts List are synchronized with the Teamcenter database.


Synchronize Callouts

By default, the NX callout values are synchronized with the Structure Manager Find No. (previously called sequence numbers). You can change this by specifying a value for the Callout Management customer default (see Teamcenter Integration Customer Defaults for additional information). The value that you specify is the title of an NX attribute.

This attribute title must be one that is synchronized with Teamcenter (i.e., with a note type defined in the Teamcenter database whose type matches the title). If there is no note type defined that matches the title, then an error message displays the first time Teamcenter Integration needs to use the value of this default.

The attribute specified by your default never actually exists in the NX data structure. When you create an attribute with that title, the setting of the attribute is intercepted. Instead of the usual action, the attribute CALLOUT is created or edited, and you enter its value. The corresponding note type in the Teamcenter structure is synchronized with the attribute titled CALLOUT. This is because NX requires the attribute CALLOUT to be present for use with callouts on drawings.

If you have specified an attribute other than DB_SEQUENCE_NO to be the callout attribute, then the Find No. in Structure Manager and the attribute DB_SEQUENCE_NO on NX components is synchronized. This means that when you load an assembly and the structure is updated from Teamcenter, attributes with this title appear on components and can be used in the parts list.


Note

The DB_SEQUENCE_NO attribute is entered in the Callout: Attribute Title field on the Teamcenter Integration for NX→User Attributes, All tab in the Customer Defaults dialog.


The figure below shows the mapping, by illustrating two drawings of the same assembly together with the corresponding BOM in Teamcenter. In Case 1, the callouts have been synchronized with the Find Nos. in Structure Manager. In Case 2, the callouts have been synchronized with the note DRAW_No in Structure Manager.

Be aware that in each case the attribute title CALLOUT corresponds to the required value in Structure Manager: in the first case with the Find No. field, and in the second case with the DRAW_NO note type.

Case 1:





NX

Teamcenter Structure Manager



CALLOUT

Structure Manager Find No.


Callout Management

DB_SEQUENCE_NO


Case 2:





NX

Teamcenter Structure Manager



CALLOUT

DRAW_NO


Callout Management

DRAW_NO


DB_SEQUENCE_NO

Structure Manager Find No.


Also be aware that in each case the attribute not used for the callout is held separately and its value corresponds to the appropriate Structure Manager value (DRAW_NO in the second case with note type DRAW_NO, and DB_SEQUENCE_NO in the first case with the Find No.).

Weight is a measurement of force, not mass.  Therefore we adopted the units of Pounds-Force, or 'lbf'.  This can be important later on if and when the 'weight' of an object is to be used in a formula where force is the intended parameter.

What units are 1bf? (I just want to see lbs)

lbs = weight.

lbf = pounds force (mass under gravity).  Measure bodies will list Mass as lbm (pound mass) and Weight as lbf (pound force).  Why are they the same value?  Watch this.

The base unit for mass in the English system is the slug.

 

Where is the best place to change the density to another material like wood? (can i do this on the fly or must use customer defaults and log out and in again )

Either edit the solid density of your body:  Menu > Edit > Feature > Solid Density

Or, assign a material to the body:  Menu > Tools > Materials > Assign Materials

 

Can I set up a cell in a PMI Table to have the attribute of the weight, I have seen some info for drafting out there?

Yes, you can use the Relationships option to read the 'MassPropWeight' Part Attribute of a part file in a note or a table.

 

I assume if i have multi bodies I would just tally up the cells for total weight?

MassPropWeight stores the value for the entire part.  You could use Measure Bodies and save the weight for each body as an expression and then reference that expression (again using Relationships) in a note or a table.
