attribute blocks with expression with autocad 2011

[gino_pomicino]

Hello.
I would need to insert in the block of the cartiglio an attribute that is the result of an expression (autocad 2011).
practically have 2 data: extruded profile area / profile weight
I would like to make sure that, by inserting the area, I automatically complete the weight (p=a * 2.7/1000)
Can you help me?

Thank you very much
Hi.

you can use a "formula" field

I tried: formula field -> I entered a data (area) *2.7/1000
before completing the cartilage, the 'area' attribute has no value, when I go to insert the field with the formula that should return the weight does not update.
then I tried to insert the attribute directly with a value (e.g. 10) and at first sight it works, but if I go to change the area, the result is not updated.
Can you help me?
Thank you for your patience

once you change your starting data, to update, you can use or regenerate command (rg) or aggcampodized command

:smile:

define two attributes, the first with label area and value 0 (zero), the second with only the label weight.

creates a block that contains them, this will be displayed with only the value .

double click, in the attribute editor select the label weight, in the box value clic destro -> enter data field...in the window data field Choose data fields name: formula, in the box formula -> enter data field... (new :tongue
in the new window data field Choose data fields name: object, through the selection box click on the block (zero) and set proprietà: area (ovvero the name of the attribute whose value must be used in the formula), then by the ok.

returning to the previous window in the box formula you are proposed the value of the attribute (zero), add the desired formula, in our case *2.7/1000, then ok + ok.
the creation of the block with its fines is finished, changing the value of the area will be updated, after a rigen, also the value of the weight.

amen

I know, the problem was not time but memory; I assure you that I am very grateful for the help you give me (especially since I am asking you a question a week and more), unfortunately I am quite distracted so I happen to forget the good manners. cmq in the future I will try not to repeat the error
