I just reviewed Kathleen's project file and the problem she is seeing exists in AC 10 as well as AC 9 build 2219. So, this seems like a bug. I've suggested that she contact GSUS Tech Support with the files...
You can see the mystery splines in the attached screenshot of the layout. None of the dashed splines inside the red 'blob' exist in the file.
An interesting thing to have found out is that the Project Preview window in ArchiCAD also shows these weird splines, which are not visible in the associated plan view. Somehow related to circles and/or splines, but not clear which after a quick review...one time they went away after deleting splines. Another time, they didn't go away until deleting circles. Bizarre.
If anyone has ideas for her in the meantime, please post here.
