Custom Field / Save 'additional format'

[jpyeatt]

Hello all-

I am using a combined field / mtext to list the area of an given object. My drawing is in millimeters, and I need the area displayed in SQUARE METERS. Unfortunately, due to the units of my drawing, the default area calculations come back in SQUARE MILLIMETERS. This isn't really a problem, as I can fix this in the "additional format" window of the Field(s).

So, my text is tied to a field with the following:
OBJECT > AREA > DECIMAL (with a custom additional format to list SM)

The problem is I have not found a way to save this 'custom' conversion back to SM. Each time I re-connect the mtext object I need to manually re-apply the 'custom' additional format. It's a waste of precious time!

Is there a way to create a custom/user-defined field that will always be available?

The string / field expression is:
%<\AcObjProp.16.2 Object(%<\_ObjId 8796069715536>%).Area \f "%lu2%ps[,SM]%ct8[1e-006]">%

Help? Thanks!

To solve this, you need to add some code to acfields.fdc.

First, close Autocad completely.

This file can be found at (windows 7) C:\Users\xxx\AppData\Roaming\Autodesk\AutoCAD yyy\R17\enu\Support
You'll have to open it with notepad and search for the following code:
<FormatType name="Area">
<Formats>
<Format>
<DisplayName resource="471" src="AcFieldRes.dll"/>
<FormatString/>

After the second line <Formats> you have to copy-paste the following text:

<Format>
<DisplayName>Square meters</DisplayName>
<FormatString>%lu2%ps[,SM]%ct8[1e-006]</FormatString>
</Format>

When you open Autocad again, you'll find your custom user field that will always be visible.

Good luck!

Hello,

The solution that you wrote is perfect.
I tried to use the same method to add a new format in "formulas", but in the cfields.fdc i could not found any think related. I was wondering if there is also a way to add new format to formulas.

I added field>object>area>sqm (my new format)
i wanto to add field>formulas>new format

Thaks.
