As a result, the arcs have to be redrawn and published a second time, when everything appears normal. However after a few days, on re-opening the drawing in Plotmaker, the arcs have all flipped again, and require to be redrawn in Archicad and republished again.<BR /> <BR /> Today we found a similar thing happened when copying an arc to the next storey using 'copy and paste'. On the ground floor the arc curves from north to east - but on the first floor the arc curves from east to south.<BR /> <BR /> Has anyone any idea why this should happen?<BR /> <BR /> (ARCHICAD 9, on Mac workstations running OSX)</T></DIV> Thu, 25 May 2023 16:19:36 GMT https://community.graphisoft.com/t5/Modeling/FLIPPING-ARCS/m-p/19115#M9158 Anonymous 2023-05-25T16:19:36Z https://community.graphisoft.com/t5/Modeling/FLIPPING-ARCS/m-p/19116#M9159 This is known bug and is corrected in last version of AC!<BR /> Have you updated your AC9 up to build# 2172?
