# Architect Special Interest Group May 2017 (am)

In this session, we looked at slabs, and we looked at counting special parts, particularly objects where you might need to create a record format in order to count them.

• 00:32    We started out by looking at the concept of a slab. Vectorworks uses slabs to create flat areas, so a slab could be a floor slab or it could be a ceiling. Like walls, slabs have styles. Styles can be saved in your workgroup or user folders, or you can use a slab style from a Vectorworks library. In detail, the slabs can be connected to the components of a wall. In this example, we chose to connect the slab to the framing of the wall (timber framing) but then offset the slab 12 mm (1/2”) from the face of the timber frame. This requires going into the detail of the slab components and adjusting them to suit your situation. When you connect your slab to a wall, it stays connected when you change the position of the wall. For example, when you move one of the walls, the slab will automatically update.
• 13:41    When you create a slab style, you can choose to have more than one component for the slab, and you can control whether these components are tapered or not. When you insert slab drainage, Vectorworks will slope the entire slab (if there are no tapered components), or it will taper the selected component. As well as connecting the slab to walls, you can also control the offset of each edge of your slab individually. When you set the slab offset, the slab is still connected to the wall; so, if the wall moves, the slab updates. We looked at setting slab offsets and how to control them.
• 33:44    We looked at calculating the volume of the slab by using a worksheet. There is a worksheet formula for volume, and we only had to add a criteria that would locate the slab. The criteria can be things such as the slab’s layer, class, and object name.
• 38:19    We looked at creating box corners for a building and how we could count them. The method of counting these corners depends on the information that you want to get out of the report. For example, if you need the length of the boxed corners, then you can create extruded objects; however, the objects must be extruded in the correct direction. For some objects, you can use framing members because these will give the length and size of the objects. It is a good idea to start with a plan of what you want to report because that will guide you in selecting the modeling technique that will provide you with the necessary information.
