Select the wide slab.<BR /> 2. Select the slab tool.<BR /> 3. Hold down spacebar to activate magic wand.<BR /> 4. Click on circular slab inside the wide slab, (either the edge or middle if nothing overlaps it.)<BR /> 5. (Optional) A message may come up asking you to regularize or keep polygon, Click regularize or it may self-intersect.<BR /> <BR /> Easy-peasy. <IMG src="https://community.graphisoft.com/legacyfs/online/emojis/icon_smile.gif" style="display : inline;" /> Fri, 15 Feb 2008 15:15:47 GMT https://community.graphisoft.com/t5/Modeling/subtract-polygon-from-another/m-p/30864#M15185 Anonymous 2008-02-15T15:15:47Z
