Hello Guys, I have attached an image file below. There used to be a button right beside that symbol icon that I could click on to assign a new sumbol to this particular variable. But I dont know what I did but there is no button now as you can see in the picture. & No option to change the symbol. I know this may be potentially stupid question as I probably changed some options in layers but I cannot figure out for last hour and I was wondering if someone can help me get rid of my misery.:)
Ok I think I checked "Show Construction" checkbox. But it is not available now. SO how to uncheck that. TO see what I am talking about please see the image again https://www.dropbox.com/s/ogaswsftea1xtp3/Capture.JPG
