[#1]

Is it possible to create a field that will show only a portion of the contents within an text object? Maybe using diesel or something?

Example:

There is a text object that contains "FIRST TEST", is it possible to create a field from that object that contains the first 5 letters of the text "FIRST". If the original text was changed to "SECOND TEST" the field would be updated "SECON"

This diesel expression reads the 4th and 5th characters of the layout tab name. Change the variable and numbers to suit your needs. Caution; True View and I think LT also does not recognize diesel.

$(substr,$(getvar,ctab), 4,2)

Thanks! Is there a way to use that on just a text object and not a ACAD variable?

[#4]

In the diesel help there is only GETENV and GETVAR listed so AFAIK you can only get system and environment variables. Can you describe a little more in depth what you are trying to do?

[#5]

I want the field to be linked to a piece of text, so that when I update the text the field will update with only part of the originally text.

Let's say I only want the second word of the text to display in the field.

"TEST ONE" - would display "ONE" in the field.

If I editied the text to "TEST TWO" the field would now display "TWO"

Hopefully that makes sense?
