Calculate with Reporting parameter in family

[Anonymous]

Hello,

I try to make some calculations with reporting parameters, but I can't get it to work. Does anyone know how to get around this problem? I know I can do these calculations in a list in the Project but I like to do it the family.

Thanks

What's the purpose of making them Reporting Parameters?

The purpose is to find the area of the inner triangle. I figure it would be easier then find out the formula to do this based on the outer dimensions. The angle of the triangle can be changed as well which makes it more complicated.

I thought this could be a work around. But it seems I can't use reporting paramaters for this purpose in a family?

It is not much more complicated using formulas.
Outer height = H
Long width = L1
Short width = L2
Offset = d

Inner Area = (H - 2*d) * ((L1 + L2)/2 - 2*d)

Angle does not matter

how about...

INNER AREA=(BreddeBRA*LengdeBRA)+((BreddeBRA*TriangelBRA)/2)

...or

Hello and thank you for your input.

This is the result I'm getting, I guessing I'm missing something here? I've made a filled region that show the correct result. The result I'm getting is only aroung half of what I'm looking for. Some how it looks as the triangel is missing somewhere. (Or more likely, my math skills suck!)

Anyway, thanks for trying to help me.

Aren't you just trying to get the combined area of a rectangle and a right triangle?  

Rectangle=Length *Height

Right Triangle=(Length * Height)/2

Add results together. No?

In my post, Long width means the long side = 10000, short width means the short side = 6000.

Basically yes. But given the dimensions that I have. When I try to calculate the area in blue (whick I'm looking for) I get a narrow area between the rektangle and the triangle which I can't figure out how to solve. 

[barthbradley]

I don't know how that is possible. Maybe I'm misreading your first screenshot.  Want to post your family so we can see what actual construction dimensions you have?

Of course, here's the family

I see, it's close but there is still some m² missing. 

[barthbradley]

INNER AREA=(((Breddeti-(2*Tykkelse Yttervegg))*(Lengde-Tykkelse Yttervegg))+((Bredde-(2*Tykkelse Yttervegg))*(Lengde Triangel-Tykkelse Yttervegg)/2))

I think this works. It's based off your actual construction dimensions in your nested family.

...edited and corrected.

...Sorry. Edited again to add some parentheses.

INNER AREA=(((Breddeti-(2*Tykkelse Yttervegg))*(Lengde-Tykkelse Yttervegg))+((Bredde-(2*Tykkelse Yttervegg))*(Lengde Triangel-Tykkelse Yttervegg)/2))

Thank you, this is also close but "Lengde Triangel - Tykkelse Yttervegg" doesn't equal the actual length of the inner triangle.

I guess this is harder then it looks. I gonna give this some serious thought and come back with a formula... hopefully 🙂

[barthbradley]

HA! I see where your challenge is now.  You need some Trig to figure out that chuck of area. That area total needs to be subtracted from the sum yielded by the above equation.

....now I totally get where @ToanDN was coming from.  

[ToanDN]

What is the family for? Can you use something with the area built-in such as floor, property line, etc...?

[barthbradley]

Take at look at the attached file.  It'll blow your mind seeing what it took to figure out that area (parameter "a"). 

BTW: you don't need all those parameters. Some are just informational data I wanted.  

[ToanDN]

I would simply build it in project to take advantage of the program's automatic calculation.

@Anonymous: I got it down to one parameter: 

INSIDE AREA =

((Bredde - (2 * Tykkelse Yttervegg)) * (Lengde - (Tykkelse Yttervegg + ((Tykkelse Yttervegg / 2) * tan(c)) / tan(c)))) + ((Bredde - (2 * Tykkelse Yttervegg)) * (((Tykkelse Yttervegg / 2) * tan(c)) / tan(c))) - (((((Tykkelse Yttervegg / 2) * tan(c)) / tan(c)) * ((Tykkelse Yttervegg / 2) * tan(c))) / 2) + (((Bredde - ((2 * Tykkelse Yttervegg)) - ((Tykkelse Yttervegg / 2) * tan(c))) / tan(c)) * (((Bredde - (2 * Tykkelse Yttervegg)) - ((Tykkelse Yttervegg / 2) * tan(c)))) / 2)

Copy and paste into your Bygg_04V.rfa.

Sorry for Pinging you guys so much.  This is my final, final answer. This one will work as-is inside the Bygg_04V.rfa. Promise. Just tested.  

INSIDE AREA=

((Bredde - (2 * Tykkelse Yttervegg)) * (Lengde - (Tykkelse Yttervegg + ((Tykkelse Yttervegg / 2) * tan((atan(Bredde / Lengde Triangel))) / tan((atan(Bredde / Lengde Triangel)))))) + ((Bredde - (2 * Tykkelse Yttervegg)) *(((Tykkelse Yttervegg / 2) * tan((atan(Bredde / Lengde Triangel)))) / tan((atan(Bredde / Lengde Triangel))))) - (((((Tykkelse Yttervegg / 2) * tan((atan(Bredde / Lengde Triangel)))) / tan((atan(Bredde / Lengde Triangel))))* ((Tykkelse Yttervegg / 2) * tan((atan(Bredde / Lengde Triangel))))) / 2)+(((Bredde - ((2 * Tykkelse Yttervegg)) - ((Tykkelse Yttervegg / 2) * tan((atan(Bredde / Lengde Triangel))))) / tan((atan(Bredde / Lengde Triangel))))* (((Bredde - (2 * Tykkelse Yttervegg)) - ((Tykkelse Yttervegg / 2) * tan((atan(Bredde / Lengde Triangel)))))) / 2))
