The vertical SCTN is extended past the cross bar by the application overlap value, as shown below left, in order to weld the SCTNs together. In some circumstances the vertical member may need to be flush with the top of the cross bar.

To achieve this, set the uda :MdsOlap value at the vertical SCTN to OVERLAP and the uda :MdsOnum value to -100 (if the cross bar depth is 100).
The following example is the standard/default configuration with the :MdsOlap unset <default>.

The example below assumes a common template SCTN size of 100x100x8 angle. The vertical SCTN uda :MdsOlap value is set to OVERLAP and the :MdsOnum value is set to -100, (the depth of the cross bar being 100).
