If you'd identify whether the instance of 'A' and 'B' are the same type (door, for example), then you can check whether the value of element.door.openingBase.libInd is the same or not.</P> <P>HTH.&nbsp;&nbsp;</P> Fri, 11 Apr 2025 06:29:26 GMT Hiromichi Shinkawa 2025-04-11T06:29:26Z https://community.graphisoft.com/t5/Archicad-C-API/Get-elements-of-the-same-type-by-GUID/m-p/657996#M10238 <P>Hello everyone. I am trying to implement one functionality where I use a GUID of an element "A" to iterate over the elements ("B", "C", "D"...) that match the type of element "A".<BR /><BR />So by using a guid of a door I want then to iterate over the other doors that are the similar instance.</P> <P>&nbsp;</P> <P>Thanks for the help in advance!</P> Wed, 02 Apr 2025 11:38:19 GMT https://community.graphisoft.com/t5/Archicad-C-API/Get-elements-of-the-same-type-by-GUID/m-p/657996#M10238 Emkave 2025-04-02T11:38:19Z https://community.graphisoft.com/t5/Archicad-C-API/Get-elements-of-the-same-type-by-GUID/m-p/659055#M10262 <P>Hi, Sorry I'm not so clear what you'd like to do. the guid is generated automatically by Archicad when you placed on floor plan, or each object has its own guid which is stored in gdl library part (API_LibPart.ownUnID).
