Dynamic Block, Field "value" not updating Attribute "value"

I have created a rectangle whose length changes.


The value of the paameter "Dist1" is this length field that I associate to the attribute value. Basically, echo length from Dist1 into the attrib value.


The problem is when I insert the block into the drawing the value is shown as "DIST1", even after regen. 


Once I pull the grip point to a new length and regen it still shows "DIST1".


If I go into the ddedit and select the edit box (for multiline data field) the shown value will correct itself, but only one time.

If I change the length again, the dimension does not update. 


It worked fine when I tested the block but is having issues days later.

Any suggestions?  thx .j.

Is FIELDEVAL set to 31?

If by some odd chance my nattering was useful -- that's great, glad to help. But if it actually solved your issue, then please mark my solution as accepted :smileyhappy:

I found this in the AutoCad Command Reference


To update fields automatically

  1. At the Command prompt, enter fieldeval.
  2. Enter a bitcode that is the sum of any of the following values:
    • 0: Not updated
    • 1: Updated on open
    • 2:Updated on save
    • 4:Updated on plot
    • 8:Updated on use of ETRANSMIT
    • 16: Updated on regeneration

    For example, to update fields only when the file is opened, saved, or plotted, enter 7.


    Saved in:Drawing
    Initial value:31

    Controls how fields are updated.

    The setting is stored as a bitcode using the sum of the following values:



    Not updated


    Updated on open


    Updated on save


    Updated on plot


    Updated on use of ETRANSMIT


    Updated on regeneration

    NoteThe Date field is updated by UPDATEFIELD, but it is not updated automatically based on the setting of the FIELDEVAL system variable.

    I hope this helps
