 So I am wondering if it&amp;#39;s possible to trim all lines to the mesh as the picture shows or if I have to go the intersection way and manually extend every line to the intersection point. Thankful for answers.

&lt;p&gt;Try this:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Use the &lt;strong&gt;Extrude Mesh Volume&lt;/strong&gt; command. With &lt;span style="text-decoration:underline;"&gt;Keep Original&lt;/span&gt; &lt;strong&gt;checked&lt;/strong&gt;,&amp;nbsp;extrude the mesh far enough to enclose the ends of all of the lines.&lt;/li&gt;
&lt;li&gt;Make&amp;nbsp;copies of all the lines and change their color and weight to make them stand out from the originals.&lt;/li&gt;
&lt;li&gt;&amp;nbsp;Use &lt;strong&gt;Surface By Extrusion&lt;/strong&gt; to extrude these copies well beyond the mesh volume.&lt;/li&gt;
&lt;li&gt;Use&amp;nbsp;&lt;strong&gt;Trim Surfaces&lt;/strong&gt; to trim these newly extruded surfaces with the mesh volume.&lt;/li&gt;
&lt;li&gt;Delete the mesh volume&lt;/li&gt;
&lt;li&gt;Select all the extruded surfaces and use &lt;strong&gt;Drop Element&lt;/strong&gt; to drop them to wireframe lines.&lt;/li&gt;
&lt;li&gt;Select and delete the unwanted lines (This is the reason for the color/weight change in step 2. It makes it much easier to do this step.)&lt;/li&gt;
&lt;li&gt;Now you should be left with the original elements and new lines trimmed to the mesh.&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;This video shows show the process.&lt;/p&gt;
