Request - Fixed square metre

Question is, are we talking about simple squares?

let's start simple with a square...

But it gets really tricky once you move passed a simple square. Its easy to resize a square to a rectangle and tell it to maintain a desired area. But changing the floorplan of a house is another story.

and if its irregular shapes, its even worst. WHERE to change the shape so as to maintain the area???
isnt it more rational, and not so difficult, to keep the entity info window open and resize and change the shape, keeping an eye at the area?
-
And how to let the user "lock" pieces of the floor plan that he likes, and how to take into consideration lot boundary limits, setbacks, etc, etc., etc...
These are a few of the reasons it probably has not been written yet. Lots of work for a "what if" type of tool.

A simple version would be a rectangle inside a group.

have you tried driving dimensions plugin? this may help if i understand correctly. they're also going to implement dynamic dimension linking and equations so this could get you where you're going??

I guess the enclosure can be simply triangulated and area recalculated and reported after every move.
Rethink - use the entity info as AcesHigh suggests above or extract the area to a web dialog so it can be incorporated into an analysis or somesuch.
I wonder why the entity info result is in square millimetres not square metres to two places of decimals as is common in sensible metricificated places.

Is there any script which fixes the square metres of a object? I think this could be very useful. For architects for example sometimes a client wants a certain square meter.
Not a script but an idea how to tackle this thorny question particularly related to floor areas. I say thorny because so much faith is put into square foot allowances that it can override better considered design criteria. More later.
Anyway the idea is based on creating SU elastic nets (something like bounding boxes). Components are used to "fill out" these nets, the extremes being joined by straight lines (as is the case with elastic). Moving a component beyond a boundary will expand the net. As all the boundaries are straight lines, I guess the enclosure can be simply triangulated and area recalculated and reported after every move +++ see post after next.
From my point of view this would help illustrate a proper balance between historically strong square foot allowances, physical and legal site limitations and practical or aesthetic proportions, amongst other considerations.
SQUARE FOOT ALLOWANCES
Here is one source of square foot allowances and here a calculation.
Circulation area allowances account for some 40% of the gross. Let's assume that is accurate. Supposing there is a change to the accommodation resulting in this:
About 35% has been knocked off the circulation allowance but there may well be the same legal and practical minimum requirements for toilets, elevators, primary and secondary means of escape and so on.
With Sketchup we can deal directly with models like the ones in the website linked above, and simply substitute calculation with modelling.
What do think?

See toggle units. Thanks Matt!
