    <description>&lt;P&gt;I have received an old .rvt file. I wish to open it; however, I cannot. I apologize in advance for my ignorance here.

      <description>&lt;P&gt;Unfortunately, this is not the best place to ask such a question.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Afaict, you are not doing anything programmatically yourself using the Revit API, just using the standard Revit user interface.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;So, you cannot expect an answer to a question such as yours relating to product setup, optimisation, usage or other end user support issues here.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;You should try one of the non-API Revit product support discussion forums instead for that:&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;A href="https://forums.autodesk.com/t5/revit-api-forum/this-forum-is-for-revit-api-programming-questions-not-for/td-p/5607765" target="_blank"&gt;https://forums.autodesk.com/t5/revit-api-forum/this-forum-is-for-revit-api-programming-questions-not-for/td-p/5607765&lt;/A&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;The people there are much better equipped to address this topic than us programming nerds.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Even if you were doing anything programmatically, please be aware that the Revit API hardly ever supports any functionality that is not also available in the user interface.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;T Revit API generally only supports functionality that is also available in the end user interface.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Therefore, if the UI does not support this, the API will probably not do so either.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;So, it will always help to research the optimal manual approach to a solution first, before attacking the task programmatically.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I hope this clarifies.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Thank you for your cooperation and understanding.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Best regards,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Jeremy&lt;/P&gt;
