Representation of vertical spans parting from drainage equipment

In the previous version of CYPEPLUMBING Sanitary Systems, the program did not represent vertical spans parting from drainage equipment in the 3D view nor did it export them to IFC format (although they were taken into account in the analysis and design). As of this version (2018.g), these vertical spans are represented in the 3D view and are exported to the IFC that is generated by the program.
