<p>I would like to select all faces, which are both coplanar to my selected face and have the same area as my selected face.</p> <ul> <li>If I do &quot;Select Similiar&quot; -&gt; &quot;Coplanar&quot; I get other coplanar faces, but with different area.</li> <li>If I do &quot;Select Similiar&quot; -&gt; &quot;Area&quot; I get other same area faces, but which aren't coplanar.</li> </ul> <p>So I'd like to know if there's a way to get the intersection of these two sets of faces. (or a way to logically &quot;AND&quot; combine these two conditions)?</p>

So there is no crossing areas or directions between selections.</p> <p><a href="https://i.sstatic.net/fzQqKax6.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/fzQqKax6.png" alt="Nodes 2" /></a></p> <p>These nodes use the same comparison logic as before, but it makes copies of the original geometry for each selected face, so it's possible to compare each area respectively with each selection.</p> <h1>Multi selection solution - lenient</h1> <p>This is very similar to the previous solution, but less restrictive, following <code>(area1 OR area2) AND (direction1 OR direction2)</code>. So, when you select two or more different areas and angles, you can get faces that can contain <code>area1 with direction2</code> and also faces that contain <code>area2 with direction1</code>.</p> <p>The general setup is the same, only the comparison changes, accumulating each field before the <code>AND</code> operation:</p> <p><a href="https://i.sstatic.net/fzFTthE6.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/fzFTthE6.png" alt="Nodes 3" /></a></p> <h1>File</h1> <p>Contains all three solutions.</p> <p><a href="https://blend-exchange.com/b/yp8QqB6y/" rel="nofollow noreferrer"><img src="https://blend-exchange.com/embedImage.png?bid=yp8QqB6y" /></a></p>
