    <title>topic Combine value definitions in Properties-manager? in Project data &amp; BIM</title>
    <link>https://community.graphisoft.com/t5/Project-data-BIM/Combine-value-definitions-in-Properties-manager/m-p/399529#M9635</link>
    <description>&lt;P&gt;Hello,&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Anyone knows any trick how to combine value definitions in Properties-manager? is that possible?&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="1_string and option set.png" style="width: 737px;"&gt;&lt;img src="https://community.graphisoft.com/t5/image/serverpage/image-id/46299iD5B3712B00341841/image-size/large?v=v2&amp;amp;px=999" role="button" title="1_string and option set.png" alt="1_string and option set.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;I would like to combine string with option set.&lt;BR /&gt;With sting&amp;nbsp; chosen I can add any text, while with option Set I can only choose from the option set:&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="2_string_can add any text.png" style="width: 896px;"&gt;&lt;img src="https://community.graphisoft.com/t5/image/serverpage/image-id/46298i6577FAAC81A1F404/image-size/large?v=v2&amp;amp;px=999" role="button" title="2_string_can add any text.png" alt="2_string_can add any text.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="3_Option Set_can only choose from the options.png" style="width: 999px;"&gt;&lt;img src="https://community.graphisoft.com/t5/image/serverpage/image-id/46300i990AFC981D653DFA/image-size/large?v=v2&amp;amp;px=999" role="button" title="3_Option Set_can only choose from the options.png" alt="3_Option Set_can only choose from the options.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;I would like to use Option set as default, but still have the option to add text later while modeling - as we can do with value definition of string.&amp;nbsp;&lt;BR /&gt;Maybe there is some workaround for it, or should I approach and set value definitions differently?&lt;BR /&gt;&lt;BR /&gt;I appreciate any advice &lt;span class="lia-unicode-emoji" title=":slightly_smiling_face:"&gt;🙂&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

      <description>&lt;P&gt;Hi ananas,&lt;BR /&gt;&lt;BR /&gt;How about using the following workaround:&lt;/P&gt;
&lt;OL&gt;
&lt;LI&gt;Set the &lt;STRONG&gt;Default Value&lt;/STRONG&gt; of your String property (named 331 in your case)&amp;nbsp; to &lt;EM&gt;Undefined&lt;/EM&gt; (DE: &lt;EM&gt;Nicht definitiert&lt;/EM&gt;)&lt;/LI&gt;
&lt;LI&gt;Create another expression property (DE: Berechnung) and use following formula:&lt;BR /&gt;&lt;LI-CODE lang="markup"&gt;IF ( ISUNDEFINED ( {Property:Caala_CostGroups/336} ); {Property:Caala_CostGroups/331};{Property:Caala_CostGroups/336} )​&lt;/LI-CODE&gt;&lt;/LI&gt;
&lt;/OL&gt;
&lt;P&gt;This new property will only display a new custom text if you manually set a text for the 331 property.&lt;BR /&gt;Otherwise, it will display the selection of the 336 property.&lt;BR /&gt;This way you have the option set with property 336 and the custom text with property 331.&lt;BR /&gt;&lt;BR /&gt;Does this help in your situation?&lt;/P&gt;</description>
