Hi everyone!
I have developed an application which open a dialog window to select multiple drawing files and prompt user to specify the layer name, then iterate through all files one by one and select a rectangle by the user specified layer. And then make its vertices the plot area and then plot to pdf. But it's doing nothing. I don't understand why? Need help.
