Shape edit elements to provide a surface sloping in multiple directions.
Create a slab with slope or multiple sloping faces with the shape editing tools. Shape editing tools are available on slabs without slope defining edges or slope arrows.
In this video learn the following:
The Shape Editing tools allow you to transform a flat slab element, roof, floor, or toposolid into an element with a complex sloping surface. The surface can slope in multiple directions with different slope angles.
One application for a shape edited slab could be a roof on a large building, like this drug store for example. Use shape editing to add internal drains to the roof, built using sloped insulation.
First select the roof. The shape editing tools display on the contextual tab. Use pick supports to split the roof element at the supporting beams. This also adjusts the position of the roof if the support and the roof are not aligned.
Click to add a split line to further divide the roof. Next click Add Point to add the points for the roof drains. Use the settings on the ribbon to control the elevation of the points as you place them. Points can have an absolute value from a base point, or like in this case, the points are set along the surface with an offset value. The roof geometry is adjusted as you place points.
If required, you can click Modify Sub-Elements to make changes to other points and edges of the roof. Adjustments are made either using the control grips in the canvas, or on the contextual tab by setting a value in reference to the selection.
In a section view, you can see how the shape of the roof slab was altered. If the design intent is to have a flat portion of the slab while others are variable, adjust the structure of the roof type. In this example, the insulation layer is set to be variable. Now the bottom of the slab remains flat and the insulation layer, and all layers above it, are sloped.
Use the shape editing tools on flat slabs to create elements with multiple slopes and variable thickness layers.
