How to apply multiple "if" expressions (Subassembly composer)?

[joseley_gildo]

For example, I want to apply to Delta X and Delta Y of a single point, assuming multiple "if" expressions:

if(TDrenagem.Value="Valeta",XDrenagemSolo+WSolo+.3,XDrenagemSolo+EDrenagemSolo*2+WSolo)

And

if(TDrenagem.Value="ValetaTrapezoidal",XDrenagemSolo+WSolo+.6,XDrenagemSolo+EDrenagemSolo*2+WSolo)

And

if(TDrenagem.Value="NA",WSolo,XDrenagemSolo+EDdrainagemSolo*2+WSolo)

I already tried to insert "else" "if-else" "else-if", but the expression does not accept the continuity of the code...

Hi @joseley_gildo 

Can you attach PKT file to check all variables ?

You could use a switch Statement instead.

In Subassembly Composer, you can apply multiple "if" expressions using nested conditional statements. Combine the three expressions into one by checking each condition sequentially: If TDrenagem.Value is "Valeta", calculate XDrenagemSolo + WSolo + 0.3; If "ValetaTrapezoidal", calculate XDrenagemSolo + WSolo + 0.6; If "NA", calculate WSolo; Otherwise, calculate XDrenagemSolo + EDrenagemSolo * 2 + WSolo. Test the code with various input values to ensure proper functionality. Replace EDdrainagemSolo with EDrenagemSolo in the third expression.

How did I not think of the switch? It worked, it was exactly what I was wanting.
Thank you very much for your contribution.

I managed to solve it with the "switch" solution. But I was curious about the functioning of the "if", I tested separating the "if" with ";", but it does not accept the continuity of the expression...
thank you for your contribution

Hello Everybody, 

I want also make a .pkt file/subassembly based on decisions.

To be more detailed, i want to put a code in the shape witch is based on different factors that will be determined in Civil3d by inputparameters. So one combination off that factors needs to give one unique code.

But the use of the "IF" and "AND" in de expression editor doesnt work in my pkt file...anyone knows why this is giving an error? The error message says (translated from dutch) "Cannot derive a general type because multiple types are possible"

I attached the pkt file also

Many tnx already if you are watching this and would give a solution for this problem!!
