Sloping slab drainage

Sloping slab drainage creates a concrete slabplate that represents a concrete structure

In Tekla Structures, a slab is created by picking three or more points.

Slab may be part of a floor, for example.

topping and a drainage holesmall hollow open throughout a part or assembly that is usually used for fastening parts with bolts or other such objects

Hole is created in the same way as bolts and hole properties are defined in the bolt properties.

Slab topping does not adapt to slab chamfers. You need to define the slab chamfers and topping chamfers separately.

Before you start

Create or split the slabs so that there is one drainage point in each slab.
