The window shows up in 3d but just shows a blank space in the plan. If someone has an idea of what is wrong with either the window or the wall I would appreciate it. Thanks</T></DIV> Wed, 24 May 2023 09:58:07 GMT https://community.graphisoft.com/t5/Libraries-objects/error-message/m-p/176244#M24985 Anonymous 2023-05-24T09:58:07Z https://community.graphisoft.com/t5/Libraries-objects/error-message/m-p/176245#M24986 Welcome to the forum.<BR /> As our fellow forum member David Maudlin would suggest,<BR /> You should add a Signature to your Profile (click the Profile button near the<BR /> top of this page) with your ArchiCAD version and operating system<BR /> (see mine for an example) for more accurate help in this forum. <BR /> <BR /> The name of the macro in the error message you quote is incomplete <BR /> because it should have a version number at the end of the name.<BR /> <BR /> Do a search using the key word wa_trim_us and you will find many<BR /> threads concerning this particular macro and how to get it to work.<BR /> <BR /> Peter Devlin Wed, 18 Feb 2009 00:57:30 GMT https://community.graphisoft.com/t5/Libraries-objects/error-message/m-p/176245#M24986 Anonymous 2009-02-18T00:57:30Z
