Floor / modify sub elements - HELP

[Anonymous]

I am trying to make a sloped floor for a showering room. The contours of the floor aren't cast from all the corners of the "L" shaped floor, but Revit automatically triangulates from all points around the perimeter.

Attached is a picture. The highlighted parts are the four corners the floor should slope from and the drain at the center.

Select floor. Add split lines from drain to corners. Adjust level at inner corner using shape handle if you want a 100% sloped floor and same level at perimeter.
