PLUGIN REQUEST - GFA Calculation

[haynesc]

Hello

the may already be a plugin for this - I dont know

See attached image

I would like a plugin to display the AREA and GFA of a group like the one shown as red

GFA = [AREA] * [FLOORS] ....

[FLOORS] = [HEIGHT] / [FLOOR TO FLOOR HEIGHT]

[FLOOR TO FLOOR HEIGHT] = USER SPECIFIED

Any thoughts ?

Might be difficult to do for building volumes that have different floor areas, heights, etc.

[sdmitch]

For a simple block, load and run the following code from the Ruby Console

def gfa_calc
	mod=Sketchup.active_model
	sel=mod.selection
	if sel.first.is_a?(Sketchup;;Group)
		ans=inputbox(["Floor to Floor spacing"],[3.m],"GFA calculation")
		if !ans then return end
		f2f=ans[0].to_l
		unit=Sketchup.active_model.options["UnitsOptions"]["LengthUnit"]
		case unit
			when 0;uf = 1.0;u="inches"
			when 1;uf = 12.0;u="feet"
			when 2;uf=0.03937007874;u="mm"
			when 3;uf=0.3937007874;u="cm"
			when 4;uf=39.37007874;u="m"
		end
		width=sel.first.bounds.max.x - sel.first.bounds.min.x
		depth=sel.first.bounds.max.y - sel.first.bounds.min.y
		area = (width * depth)/ uf**2
		height=sel.first.bounds.max.z - sel.first.bounds.min.z
		floors = height/f2f; height /= uf; ta = area * floors
		UI.messagebox "Area;     #{area}\nHeight; #{height}\nFloor to Floor; #{f2f}\nFloors;  #{floors}\nGFA;     #{ta}"
	end
end

A few dialog popups to assign building names to simple blocks and produce a schedule for all of them would be nice

Assuming each Building is a Group ... you could name the Group - "CP-03" - Building Name

Data for CP 03

From Skecthup :

Area
Height

From Data Entry:

Floor-to-Floor Height

From Formula Calculation:

Floors: [Height] / [Floor-to-Floor Height]
GFA: [Floors]*[Area]

GFA_Report.rb is my attempt to solve your problem. In addition to displaying the information in a messagebox, it writes it to a .txt file.

thanks sdmitch ...

Its a start ... What I was thinking of was a dialog box system that would work as a live & update-able schedule for Assigned Buildings ...

Something like my attach image

[sdmitch]

That's just a little beyond my limited ability. Maybe someone else has done something like that. Good luck.

funny to find your request here, was looking for the same thing for same project on our end... will let you know if i find anything...

BUMP

Just wondering if anyone has had any progress with this? ...

Look at doing it with a Dynamic Component: you can then set/scale to give the rectangular footprint and height, enter the story height, name, color etc - it'd then calculate the footprint area and GFA automatically for you etc. Each instance is individually editable, or you can edit several together, or report on the selected ones etc at any time...

Have you had a look at http://www.modelur.com/ ? Might that be something for you?
