Grasshopper

algorithmic modeling for Rhino

Hi, I got an issue with text file export.

The attached code is to simply export X, Y and Z coordinates of points into a CSV format.

I'm using StreamWriters since there is a bunch of points to export.

The attached code works fine actually, but when it finished writing a file, the Grasshopper turns incapable of dragging the canvas. Zooming works.

This can be fixed by clicking the boolean button again, and close the SaveFileDialog without saving anything. By doing this, I can get back the control over the canvas.

So what's wrong should be somewhere in the if(savefile.ShowDialog() == DialogResult.OK){} section. I cannot identify what it is. I tried adding sw2.Close() in the end, but nothing has changed.

Is anybody available to advise me what's wrong with this code?

Thank you.

I know this is not realy a fix, but try using a boolen toogle instead of a button.

another thing that could help is

Bingo, RhinoApp.Wait() worked! Thank you!

It should be exactly here. Nowhere else worked.

No, sometimes it works, but sometimes doesn't.

So simply, we should use Boolean toggle, not a button.

Why I didn't like Boolean toggle is that sometimes I leave it on, save the document and close. After that, when I open the document the CSV writer runs. When it happens, it's hard to identify which Boolean toggle is kept on.

Hi Miki,

I have same topic here,

So far the script works well, but I'm not sure if you want the same result with what I did.
You can check the definition below.
