At the moment I'm busy with creating a railwaystation on scale 1/87. This building excist in real (Weert the Netherlands). During the progress I always create a STL to lookup in Netfabb if I'm doing right. Unfortunately even after the repair there is still an issue in the tower. Can somebody advice how to fix? Unfortunately I made a lot of progress since the older version of the file so I don't hope I need to go back to an older file.
