    <description>&lt;P&gt;If you are really working on a 2D model, then use DIMLINEAR or DIMALIGNED because you are restricted to 2 dimensional distances, e.g. from the beginning of the driveway to the end of the driveway where you enter the garage. If you use MEASUREGEOM you are measuring in 3 dimensions, e.g. from the beginning of the driveway to top of the garage door of the garage door entrance.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Since you mentioned you use the MEASUREGEOM regularly, it sounds like you frequently measure 'ground' distances where the surface elevation fluctuates from point A to point B. If you are measuring&amp;nbsp;&lt;EM&gt;architectural distances,&lt;/EM&gt; then you should measure in 2D, not 3D, so the trades don't freak out when they cut lumber, steel and pipe. Inaccurate cuts may make the finished building lean-to-one-side and they might the blame drafter who used the wrong Cad tool.&lt;/P&gt;</description>

      <description>&lt;P&gt;I am working in AutoCAD 2D model space on a dwg file provided by an architectural draftsman.&amp;nbsp; Dimensions produced by the DIM command seem correct compared to the pdf file I was provided with.&amp;nbsp; However, when I try using the Measuregeom tool, results are inaccurate by slightly more than 100% larger measurements.&amp;nbsp;&amp;nbsp; I use the Measuregeom tool regularly, I have no idea how to correct this so I can use the tool when drawing.&amp;nbsp; I appreciate your thoughts.&amp;nbsp; Thanks!&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;FONT color="#333399"&gt;&lt;EM&gt;&amp;gt;&amp;gt; Dimensions produced by the DIM command seem correct &lt;/EM&gt;&lt;/FONT&gt;&lt;/P&gt;
&lt;P&gt;&lt;FONT color="#333399"&gt;&lt;EM&gt;&amp;gt;&amp;gt; compared to the pdf file&lt;/EM&gt;&lt;/FONT&gt;&lt;/P&gt;
&lt;P&gt;A PDF file can show some text, but does not show any real dimension as it is scaled to a paperformat and never a 1:1 size.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;EM&gt;&lt;FONT color="#333399"&gt;&amp;gt;&amp;gt; when I try using the Measuregeom tool, results are inaccurate &lt;/FONT&gt;&lt;/EM&gt;&lt;/P&gt;
&lt;P&gt;&lt;EM&gt;&lt;FONT color="#333399"&gt;&amp;gt;&amp;gt; by slightly more than 100% larger measurements&lt;/FONT&gt;&lt;/EM&gt;&lt;/P&gt;
&lt;P&gt;If &lt;STRONG&gt;&lt;FONT color="#333399"&gt;_DIST&lt;/FONT&gt;&lt;/STRONG&gt; shows a different value to the expected value than most probably the geometry you have measured is incorrect drawn.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;FONT color="#333399"&gt;&lt;EM&gt;&amp;gt;&amp;gt; I have no idea how to correct this&lt;/EM&gt;&lt;/FONT&gt;&lt;/P&gt;
&lt;P&gt;You might scale the geometry using option&lt;STRONG&gt;&lt;FONT color="#333399"&gt; _REFERENCE&lt;/FONT&gt;&lt;/STRONG&gt; within the command &lt;STRONG&gt;&lt;FONT color="#333399"&gt;_SCALE&lt;/FONT&gt;&lt;/STRONG&gt;.&lt;/P&gt;
&lt;P&gt;But first I would look to the source of the issue. Where are the data from, and at which step started the incorrect size.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

      <description>Dimensions results rely on dimstyle settings: do these actually match the DWG file's units and scale? You are assuming an apple and a banana are identical because the are both fruit in your post, which they are not.&lt;BR /&gt;&lt;BR /&gt;Please elaborate and if needed provide an actual DWG file so we can all see your work for ourselves first hand: or reach out to your draftsman and you two discuss the issues together first hand if needed.&lt;BR /&gt;&lt;BR /&gt;HTH</description>

      <description>&lt;P&gt;It sounds to me as though either there is actually a Z-coordinate difference [which Dimensions will ignore but which the DIST command {= the MEASUREGEOM Distance option} will "see"], or the Dimension has a linear scale factor applied, either in its Style definition or as an override.&amp;nbsp; The former is easy to test for -- look at the entirety of what DIST returns, because it includes a delta-Z value and an angle from the XY plane, both of which will be 0 if things are truly 2D.&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;FONT color="#333399"&gt;&lt;EM&gt;&amp;gt;&amp;gt; It sounds to me as though either there &lt;/EM&gt;&lt;/FONT&gt;&lt;/P&gt;
&lt;P&gt;&lt;FONT color="#333399"&gt;&lt;EM&gt;&amp;gt;&amp;gt; is actually a Z-coordinate difference&lt;/EM&gt;&lt;/FONT&gt;&lt;/P&gt;
&lt;P&gt;I think the dimension values would not differ then by 100%, I guess it was a PDF with scale 1:500 or so and the scaled PDF was imported without scaling it back.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;But it's difficult to know as long as we don't get any feedback from TO.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
