+- Definition : abutment of one profile on another, following the first abutment line encountered.
+Action de butée permettant à un profil de buter sur la première ligne de butée rencontrée.
+L’action permet donc de travailler avec plusieurs lignes de butée présentes sur la barre 2.

+    Example: Assembly between crossbeams and posts
+    Let's say a post profile that can be put in different orientations. 
+    The crossbeams between the posts must abut the post.
+    Add the stop line on the section of the column profile at the different possible stop points:

+
+The traverse profile (in gray) will abut the first line encountered, in the direction of the node.

+
+If additional profiles can be hooked onto the A-post and receive the crossbar stop, the process can be continued by adding the stop line on the sections of these profiles:

+Note:  
+The program will choose the first stop plane encountered by one of the four points of the profile's bounding box undergoing the cut.
