HELP: Auto Join between revit elements

<p style=“color: #000000;”>Hello everyone:</p>
<p style=“color: #000000;”>I need to know how to join in an automatic way all the model’s slabs with their surrounded beams and columns, because I’ve created these using an</p>
<p style=“color: #000000;”>Add-In based in Polylines.</p>
<p style=“color: #000000;”>I require that because I need to cut the extrusion that represent my formwork into the family of my beams and columns when the slab between these exist.</p>
<p style=“color: #000000;”>This restriction is because we need obtain the most accurate quantities.</p>
<p style=“color: #000000;”>1st image: Using the traditional process: formwork slabs cut the surrounding beams and columns.</p>
<p style=“color: #000000;”></p>
<p style=“color: #000000;”>

</p>
<p style=“color: #000000;”>2nd image: Using the Add-In: formwork slabs doesn’t cut the surrounding beams and columns.</p>
<p style=“color: #000000;”></p>
<p style=“color: #000000;”></p>
<p style=“color: #000000;”>I use Dynamo from create floors but the join between elements not is considered in the nodes.</p>
<p style=“color: #000000;”>Thanks for your help.</p>
