.DRW not updating when TABLE changed in .FRM

Remove the old format file from your workspace and clear it from memory.

Try creating a new drawing and see if the proper C format is utilized.

Is the drawing size hard coded "B" or 'C' or is it using the &format parameter?

Hi,

you described standard Creo functionality.

When you create new drawing using .frm, Creo copies tables from .frm to .drw. These copied tables are independent on tables defined in .frm.

Suggestion:

• remove current format from drawing ... apply simple frame available OOTB
• do not forget to remove all tables when you are asked
• set new format

You should not even try to enter the Revision value into the drawing format file unless it is done using a parameter that will be populated with a value later when the format has been applied to a drawing.

You cant control the revision of all of your drawings from a single value in a drawing template.

If you don't use a parameter the text must be entered into the table once the format has been applied to the drawing.

For me it’s look like you want to update the format size, like Ben was mentioning. 

For this you need to enter the format parameter in your .frm file table. 
This parameter will reflect the format for each sheet, and will update without replacing the format.
