    <description>&lt;P&gt;If by "&lt;SPAN&gt;&amp;nbsp;align the UCS to a three-dimensional SPLINE" you mean define a UCS that has it origin at the start of the spline and it z axis tangent to the spline at its beginning then (without the use of LISP) you can use the ZA option of the UCS command.&amp;nbsp; Input the first Control Vertex for the origin and the second CV for the second point.&amp;nbsp; You can use LIST to get the locations of the CVs.&lt;/SPAN&gt;&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi.&lt;/P&gt;&lt;P&gt;Is there a option to align the UCS to a three-dimensional SPLINE?&lt;/P&gt;&lt;P&gt;This is my spline&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="nathan_torggler_0-1700131503712.png" style="width: 600px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1293692i6A1A8554066C11F9/image-size/medium?v=v2&amp;amp;px=400" role="button" title="nathan_torggler_0-1700131503712.png" alt="nathan_torggler_0-1700131503712.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="nathan_torggler_1-1700131519026.png" style="width: 600px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1293693i3BD238B259A95D0B/image-size/medium?v=v2&amp;amp;px=400" role="button" title="nathan_torggler_1-1700131519026.png" alt="nathan_torggler_1-1700131519026.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;What I did is using UCS and three-points methods to define the origin. First selected the first point, then the second point.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="nathan_torggler_2-1700131617468.png" style="width: 600px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1293694iB964AB235C30E7F3/image-size/medium?v=v2&amp;amp;px=400" role="button" title="nathan_torggler_2-1700131617468.png" alt="nathan_torggler_2-1700131617468.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Then I draw my profile and extruded it along the path. Obviously there is a small mistake in the ucs, since the profile is not fully aligned with the spline. Fortunately in this case the mistake is quite small, since the first two points are close to each other and don't generate a huge error, but basically my profile is not fully perpendicular to the spline.&lt;/P&gt;&lt;P&gt;Do you know by chance a way to align the UCS perpendicular to the threedimensional spline?&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="nathan_torggler_3-1700131738628.png" style="width: 600px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1293696i63DF49014D6A18A5/image-size/medium?v=v2&amp;amp;px=400" role="button" title="nathan_torggler_3-1700131738628.png" alt="nathan_torggler_3-1700131738628.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;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Great. First UCS and then ZA. Works best when selecting Object: you can either choose start or end of spline. Aligns the UCS automatically to Spline!&amp;nbsp;&lt;SPAN&gt;&lt;img class="lia-deferred-image lia-image-emoji" src="https://forums.autodesk.com/html/@B05168100D3B24079073EF5DD0C792F6/emoticons/1f44d.png" alt=":símbolo_del_pulgar_hacia_arriba:" title=":símbolo_del_pulgar_hacia_arriba:" /&gt;&lt;/SPAN&gt;&lt;/P&gt;</description>
