We have had our preferences set for inroads for a long time and recently we started having trouble where the background mask for the text was showing up white. I looked at the text styles we are using for labeling our contours and they were both set to color 254. I set everything to bg (background) and it still isn't working the way it should. It only cuts off the lower contour not the contour in which the label is for nor the ones above it. When plotting through Iplot it plots just like on the screen. At first I thought it might have something to do with being a 3d file so I displayed my contours in a 2d file and have the same results. I looked through the forums and someone mentioned that if you change the level priority of the text level it will mask correctly. I did this and it does seem to work but then when I plot, the text no longer shows up.
I'm running 08.11.09.459 with inroads 08.11.07.615
At this point, I have no idea why it's not working anymore but just want to figure out a way to fix it. We did find a weird work around but I don't like having to do that when we didn't have to before. If you change text attributes and have graphic group on, and change the style to the same style that is used when displaying the contours in the first place, then it masks correctly and by having graphic group on it changes all of them at once.
