Walls, slabs, and roofs are designed to interact. This means that when you connect a slab to walls, will update when you move the walls. Roofs can be connected to walls so that parts of the roof are inside the building and some parts of the roof extend out to the eaves.
In order to make these connections, we need to understand how walls, slabs, and roofs connect. We need to understand how walls have been designed, has slabs have been designed, and how roofs have been designed.
When you create walls and slabs, you can connect the wall components to slab components. The first step is to set up a wall style with components. One of those components should be a core (I usually use the structural part of the wall for this).
When you create the slab, you can bind slab components to wall parts. You can’t bind to all of the wall components, but you can bind to the inner component, outer component, and core.
Slabs can be textured by object or by component. What does this mean? When you texture the slab by object, the textures are applied to the top, bottom, and sides of the entire slab, regardless of the component textures. If you texture the slab by component, the texture of each component is applied to the entire component (top, bottom, and sides).
Slab Association And Offset Edges – For a few versions now we have had the ability to connect a slab style to a wall style. This allows us to choose an association between components of the wall and the edge of the slab.
Editing Slabs That have used 3D objects. If you have used 3-D objects to edit your slab, you can right click on the slab and choose edit modifiers. You can change the location or some of the parameters (on the Object Info palette) but you are not able to change the shape of the original objects used to create the 3-D object, and you are not able to change or add additional 3-D objects. it.
When you edit a slab that has been modified, you have the option to edit the modifers. This means that you can change the modifiers to suit the change in the design. But be careful, you can only edit the modifier that is already there and you are not able to add any other modifiers. This also includes substantially changing the modifier that is already there by using add surface or clip surface on it.
As well as adding planar objects to your slabs or subtracting planar objects from your slabs, you can also add or subtract 3D objects. In the image above you’ll see that I subtract a tapered extrude from my slab to create a set down and then I add an extrude along a path to create my footing.
You can use a planar object to clip a portion away from a slab. If the slab has components then you can choose which component the planar object will clip. In these images the slab has three components and I can choose which component the rectangle will be clipping. If I use two rectangles, and use two different components, I can create a coffered portion of a ceiling. If I use several rectangles, then I can create a coffered ceiling.
You can add planar objects to a slab using Add Surface. The first step is to create your slab object. Next, draw your planar object. In the images above of use the automatic working plane to draw the planar object on the same plane as slab. Select the slab and the planar object. Right click and choose Add Surface. This will add your planar object to your slab.
Vectorworks 2015 has the ability to tightly control the the settings for walls and slabs by using Stories and Levels. This does require care planning and setting up in the Stories dialog box and in the wall and slab style dialog boxes. This session looks in detail at setting up the walls, slabs, classes, levels and stories to make sure that the walls and slabs are linked to the levels, and to each other. Continue reading →
Columns have a top bound and a bottom bound – these control the overall top and bottom of the column. There are several choices…
As with the walls and columns, you can use the story settings to control the start and stop of your stairs. But you can only control the top bound and the bottom bound of the stair, you cannot control other parts of the stair like the handrails.
Slabs have Z Ref Level – this is the level that controls the slab datum (usually the top of a slab component).
In this session we looking in detail at how to set up a wall style that uses Design Layers, Levels and Stories to control the elevations of the wall components and how to connect the wall components to slab components.
You can use the slab components to control how much of the slab is cut out. In this image the slab has been cut out one component at a time. If you need to have a set-down in the slab, you can use a component to control it.
Slabs are like walls. You can create slab styles that can be stored in your library so that you can use them on all your projects. If you set up your slab styles to work with your wall styles and stories, they will be easier to use, and when you move the walls, the slabs will update to match the walls.
When you set up your wall styles, make sure that you use your wall components to connect and control the slabs. This movie shows you how they connect if you set up the wall and slab styles; it does not show you how to set up the walls and slab styles.
