<h1>IfcDiff<a class="headerlink" href="#ifcdiff" title="Link to this heading">¶</a></h1>
<p>IfcDiff is both a CLI utility and library that lets you compare the changes
between two IFC models. Changes are made on the assumption that the GlobalId of
an element in one model is consistent with the same element in another model.
You may compare geometric changes, and changes in various IFC relationships and
properties. IfcDiff supports comparing across different IFC schema versions.</p>
<p>Changes will be sorted into three lists:</p>
<ul class="simple">
<li><p><strong>Added</strong>: a list of GlobalIds of elements present in the new file but not
present in the old file.</p></li>
<li><p><strong>Deleted</strong>: a list of GlobalIds of elements present in the old file but not
present in the new file.</p></li>
<li><p><strong>Changed</strong>: A list of GlobalIds of elements present in both the old and new
file, but changes were detected. A list of changes are provided.</p></li>
</ul>
<p>There are different methods of installation, depending on your situation.</p>
<ol class="arabic simple">
<li><p><strong>PyPI</strong> is recommended for developers using Pip.</p></li>
<li><p><strong>Using Bonsai</strong> is recommended for non-developers wanting a graphical
interface.</p></li>
<li><p><strong>Source installation</strong> is recommended for users wanting to use the latest
code as a library or a CLI utility.</p></li>
</ol>
