Problem with FOR loop at my first GH component

Hi everyone,

I'm striving hart to make my first GH componet to work. It's about connecting Grasshopper with structural engineering FEM software Strand7 through it's API. I'm using Visual Basic for this job... and GHA assembly wizard of course. At this stage I want to import some points from GH as nodes into Strand7. I wrote some code (at writing it I help myself with example that came with API)...and it somehow works, but not completely... Strand7 window opens, but insead of 169 nodes, just first one is created...it seems that For loop is not working... can samebody check it (I attached pdf with explanation what I did) and posibly find out what is wrong...

Just loop part is below:

            For i = 1 To noP
                onePoint = points.Item(i - 1)
                XYZ(0) = onePoint.X
                XYZ(1) = onePoint.Y
                XYZ(2) = onePoint.Z
                Console.WriteLine(XYZ)
                iErr1 = St7SetNodeXYZ(1, i, XYZ(0))
                Errtxt = Errtxt & iErr1
                Console.WriteLine(Errtxt)
                Exit For

Any other suggestion is also welcome.

Regards,

Damir

The "Exit For" is the cause of your problem. This command is util inside a "if...else", but here, you only need next. When execution reaches next, the loop is repeated until i reaches noP, then, execution continues after the For ... next method.
