It crashes when we try to delete a roof that has been applied with this add-on, which is a dilemma since we use modules to change our roofs. <BR /> <BR /> Is there a work around with this, or if possible a solution?<BR /> <BR /> Thanks.</T></DIV> Thu, 16 Aug 2018 08:04:34 GMT https://community.graphisoft.com/t5/Collaboration-with-other/ArchiCAD-21-crashes-due-probably-to-Roof-Surfacer-21/m-p/234470#M30091 Anonymous 2018-08-16T08:04:34Z https://community.graphisoft.com/t5/Collaboration-with-other/ArchiCAD-21-crashes-due-probably-to-Roof-Surfacer-21/m-p/234471#M30092 I am wondering if you are deleting the roof, leaving the surfacer object?<BR /> Yes, the attached object should delete as well, but I am wondering if this is what is causing the problem.<BR /> <BR /> Does it still crash if you delete the accessory first or both the accessory and roof together?<BR /> <BR /> Barry.
