To create a polygon with a hole, first delineate the perimeter, then return to the first point of the perimeter with a <FONT color="blue">-1</FONT> status code, this tells ArchiCAD that the perimeter is finished and a hole is about to start. Then delineate the hole, again returning to the first point of the hole with a <FONT color="blue">-1</FONT> status code to let ArchiCAD know that the hole is done (and another hole could be started).<BR /> <BR /> David Wed, 13 Nov 2013 13:20:16 GMT https://community.graphisoft.com/t5/Libraries-objects/Poly2-how-to-make-a-hole/m-p/212606#M13459 David Maudlin 2013-11-13T13:20:16Z https://community.graphisoft.com/t5/Libraries-objects/Poly2-how-to-make-a-hole/m-p/212607#M13460 Thanks for that. I made a an object of a fill with a hole in it and managed to suss what it was doing.<BR /> <BR /> Re. 1) <B>botlh</B> I started off with a different way of calculating it which involved other parameters and somehow those two got left in <IMG src="https://community.graphisoft.com/legacyfs/online/emojis/icon_redface.gif" style="display : inline;" /> <BR /> <BR /> Right I'm off I shall tidy up my mess Wed, 13 Nov 2013 13:44:22 GMT https://community.graphisoft.com/t5/Libraries-objects/Poly2-how-to-make-a-hole/m-p/212607#M13460 fuzzytnth3 2013-11-13T13:44:22Z
