# SST_1607 – From 2D Drawing To BIM

Just lately, I have been teaching several users who want to move from using a workflow to using Building Information Modelling (3D workflow). In the past, I had several users who would say “I want to get to the under my belt first then look at 3D.” This suggests that 2D is a productive method and that 3D is a luxury. This completely misunderstands the way Vectorworks creates drawings. 3D is not a luxury, it is an intrinsic part of the modelling/drawing process.
When you use Vectorworks effectively the 3D components are easy to create, they will create your drawings, and when you update the model it will update your plans, sections, and elevations. Not only is this fast and easy, it also saves lots of errors.

# Vectorworks Tip 442 – Creating A Cutout In A Curved Roof

Once you have the curved roof, you can use solid objects to cut holes in the roof. If you combine the solid objects first, then you can cut all the holes at the same time with one operation, using Subtract Solids.

Chicago Bean (Cloud Gate)

Cloud Gate is a public sculpture by Indian-born British artist Anish Kapoor, that is the centerpiece of AT&T Plaza at Millennium Park in the Loop community area of Chicago, Illinois. this culture has been used by Vectorworks as the icon for the Vectorworks design summit being held in Chicago in April 2016.

Sunscreen

In this exercise we want to create a curving sunscreen. This exercise uses subdivisions modelling along with some standard 3D modelling (subtract solid) to give the desired result.

Creating a Bath

In this exercise we going to create a bath. This exercise comes from one of the 3D modelling special interest groups where the user wanted to create an egg shaped bath to make some specific dimensions. One way of creating this bath is to use cross sections through the bath and loft surface to create the 3D object.

Using subdivision modelling makes this dramatically faster.

Creating a Bollard

I often use this bollard object as an introduction to 3D modelling because it is reasonably simple yet uses several 3D modelling concepts. If you have seen my Vectorworks Essentials Tutorial manual you will have completed this exercise using three extruded rectangles.

In this exercise I would like to show you how you can create this type of object.  When you first start looking at subdivision modelling you might assume that it’s only useful for complex curving shapes. This bollard however has quite sharp edges.

Now that we have looked at these modes in detail, it will be useful to look at how to create an actual object by using the various modes. Subdivision modelling is extremely powerful and it might seem strange that we only use one tool to do all of our changes. We will be changing between various modes in order to create the models that we want.

In this exercise we are going to build a shade sail. To start with I’m going to assume that the columns have already beaten created, but later on in the exercise I will show you how you could create those as well.

Controlling Subdivision Surfaces

The basic concept of a subdivision surface is the cage. This cage controls the extent of your subdivision surface and it has all the controls to allow you to manipulate it. If your subdivision object is not selected it will not have the cage visible. As soon as you select the subdivision surface, you will see a bounding box. If you double-click on the subdivision surface, you will be able to see the cage.

Face Split Mode

There are times when you are using your subdivision surface where you want to control just a small part of the face. That’s what this mode is for, it allows you to split up the face into smaller parts.

Face Extrude Mode

This mode is ideal for adding apart to your model by extruding a face. If you have used Push/ Pull tool, then you might be familiar with the concept of extruding a face. When using this concept with subdivision surfaces, the results can be slightly different, but the concept is still the same: the extruded face mode will extrude the face of the object perpendicular to the plane of it.

Transform Mode

This is the most common mode to use, it is the mode that you will use to move stretch, pull, or reshape the primitive  object. It allows you to select a vertex, an edge, a face, or several vertices.

Edit Subdivision Tool

You can access this tool by double-clicking on a subdivision surface or you can find this tool in the 3D modelling tool set.this tool is going to be your main way of interacting with a subdivision surface. It is a tool that you will be using to stretch, pull, push, squeeze, or in some way edit the subdivision  surface.

Although this is a single tool there are several modes which we will look at briefly.
