&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;A &amp;#039;&amp;#039;&amp;#039;Design ID&amp;#039;&amp;#039;&amp;#039; is a special number [[LEGO]] assigns to a specific [[mould].&lt;br /&gt;
&lt;br /&gt;
Therefore, [[part]]s with the same design ID can appear in different colors.&lt;br /&gt;
&lt;br /&gt;
[[LDraw]] aims to use the design ID numbers for numbering its [[official parts]].&lt;br /&gt;
&lt;br /&gt;
When that number is unknown, we create an &amp;quot;artificial&amp;quot; placeholder number, starting with the letter &amp;quot;u&amp;quot;, followed by a unique placeholder number.&lt;br /&gt;
