I've created a slab, with an edge beam 400d x 300w, and an edge rebate of 100d x 115w. Slab is created fine.
As this slab is on H1 soil, external slabs (i.e. the alfresco area) have to be considered as part of the main slab.
So I go and create a 100mm deep recess, with two of the edges against the inside top edge of the slab edge rebate.
The recess is created, but the edge footing only drops for a 100mm width of the 115mm edge rebate, creating a step-in along the bottom edge of the edge beam footing.
If I edit the slab, and change the edge rebate to 100w, then this step-in disappears.
The recess tool does not seem to be registering that the recess is hard up against an existing edge rebate.
