Originally when I baked the image from GH there was an issue with boolean differencing it because there were multiple polysurfaces that composed the “massing’s” I wanted to alter. I fixed that issue and when I began trying to remove from my object with polysurfaces that are suppose to encompass it, it seems to fail. I looked up possible issues and I’ve made sure they were closed surfaces. It allows for the command to work when dealing with horizontal differencing. However, I am trying to remove the excess that wouldn’t be visible in the vertical orientation. I’ve ungrouped them to try each individual vertical louver to no prevail. Any ideas on to why it works with other objects, but failed with this one?
