Hi there,

I have an attribute block with a field that updates automatically the y-value, to indicate the height in sections and facades of buildings. I didn't make it myself but I use it for many years now.
The automatically updated text has a mask function that hides the underlying elements for maximum visibility. This still displays correct on screen (grey area behind text), but for some reason my pdf outputs do not: the mask function doesn't work anymore.
Other text objects and my dimensions which have masks too still work perfect. I didn't change the attribute block nor have I changed any settings or variables. I spent an hour on Google to find a solution but nothing came up. I use LT2018

Thanks in advance!
