    <title>idea Search/Filter for Intances of '1' group en Revit Ideas</title>

    <description>&lt;P&gt;To be honest I'm not a fan of groups, so please forgive me!&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Would love to have the function which allows me to search for groups (detail or model) that have only 1 instance, so I can ungroup and purge the group.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Work with large models and when our users use groups to lazily to families it make my blood boil!&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Groups do have a purpose, I find most users miss use the groups and treat them like CAD groups.... I call it BAD Revit!&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Sorry got the rant! &lt;img id="smileymad" class="emoticon emoticon-smileymad" src="https://forums.autodesk.com/i/smilies/16x16_smiley-mad.png" alt="Emoticono loco" title="Emoticono loco" /&gt;&lt;/P&gt;

      <description>&lt;P&gt;Since it just came out today, I think I'm allowed to say this:&lt;/P&gt;
&lt;P&gt;In 2018 you can schedule Groups and one of the things you can schedule is Count.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;So you can mark this one as completed.&lt;/P&gt;</description>

      <description>&lt;P&gt;Why not to find such group types using existing functionality?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;PRE&gt;            var collector = new FilteredElementCollector(doc);

            var singleGroupGroupTypes = collector
                .OfClass(typeof (GroupType))
                .Cast&amp;lt;GroupType&amp;gt;()
                .Where(x =&amp;gt; x.Groups.Size == 1)
                .ToList();&lt;/PRE&gt;</description>
