https://community.graphisoft.com/t5/Modeling/AC18-De-merging-fills/m-p/243564#M129487 Thanks for that method. That is what I've always done. I thought that AC18 might have had a switch or something to turn this feature on or off. There are times, esp. when creating details, that it is important to show the joints between different components using the same material.

I understand that AC18 has on option to show joints if we need to. If so, where do I find this command?</T></DIV> Wed, 24 May 2023 10:43:17 GMT https://community.graphisoft.com/t5/Modeling/AC18-De-merging-fills/m-p/243561#M129484 KeesW 2023-05-24T10:43:17Z https://community.graphisoft.com/t5/Modeling/AC18-De-merging-fills/m-p/243562#M129485 .<BR /><IMG src="https://community.graphisoft.com/t5/image/serverpage/image-id/11532iA368B00E91BAFDD1/image-size/large?v=v2&amp;px=999" border="0" alt="2015-03-06_2-57-15.png" title="2015-03-06_2-57-15.png" /> Fri, 06 Mar 2015 10:58:56 GMT https://community.graphisoft.com/t5/Modeling/AC18-De-merging-fills/m-p/243562#M129485 Steve Jepson 2015-03-06T10:58:56Z https://community.graphisoft.com/t5/Modeling/AC18-De-merging-fills/m-p/243563#M129486 I guess what Steve means by his image is that you have to duplicate your Building Material, then assign one of the duplicate BMs to the Wall, the other to the Slab.
