How to copy paste formula with fields?

[yutianchen86]

I want to copy a formula and paste into mtext with field intact.  However, these fields turned into numbers when I paste.  Is there a system variable or a method that can be done to make paste as field possible? 

Thanks.

Copy this

paste into this

What you showed doesn't look like formula.

Not formula in table, I am referring to formula in fields.

Copy-paste this part:

But we usually use the other way around. Create/edit an MTEXT, Mouse RightClick, pick Insert Field...

I copyed it but pasted into this.

What does 533.41 represent? And what does 74.62 represent? What do those numbers measure?

[yutianchen86]

They are areas of closed polylines.  I don't think this matters because these fields can be any properties of any objects.

This is the actual field code, aka formula:

Yes, it does make a difference. Why? Because you are giving AutoCAD a specific set of instructions when you want to generate the field AREA.

You want a specific piece of mtext to insert a specific field, or a value. In order to do this, it must evaluate a specific object and insert the result (the property AREA) as the mtext contents. You, on the other hand, are merely pasting the RESULTS of the operation, not the operation itself. You need to re-run, or recreate, the operation. The operation, or the steps, constitutes the FIELD area.

Make another field. Start a new mtext, at your flashing cursor, go to Objects=>Formula=> and PASTE each formula like shown below, then click Evaluate, then OK to exit.

Please see the original post again.  the 1st screen shot is what I have.  I need to copy this (circled in red).  The 2nd screen shot is what I want to paste it into.  However, when I pasted it only numbers show up, not the fields. I want the fields link to remain in the mtext.

I have created two closed polyline and inserted the area of closed polyline as field in mtext. Is this what you were after?

@yutianchen86 

First question: why?
Why do not you create the title block in MText? (inside TEXT MTEXT TEXT ATTRIBUTE .. -> RightClick -> add field)

If you have existing formular fields and would therefore like to copy:

Open the object to edit (example: Double click a TEXT or whereever your formular field is),

copy the field from there.

screencast was missing in my earlier post.

Sorry for the confusion, I need to further explain my case.

This single fields within a field is generated is by Lee Mac's Length & Area Field LISP.  It automatically sums all geometry area into one single field.

http://www.lee-mac.com/lengthfield.html

I want to extract the calculation of these areas in a printed drawing.

I have many operation like this I want to be able to copy and paste directly into "field"+"field"+"field"....

However, when I copy and paste, the fields turned into numbers with no link. It would be ideal to paste into fields so in the future they will update upon regen when I modify the geometries. 

Samething when copying mtext with fields.

Again Autocad might night have such function or system variable.  I am just wondering.

Thanks.

For those of you is also looking for solution to this,  I was able to find a work around using Lee Mac's Copy Field Lisp.

http://www.lee-mac.com/copyfield.html

Execute the lisp, pick the origin field, then click the target text twice.  exit out of the command.  Double click into the new field, then delete front cExpr text.

How to get formulas without copying?

[cadffm]

?

Start FIELD command and create a formula field.

Not the answer you are after? Then explain it better  please.
