# 3D Modeling Special Interest Group – May 2016 (am)

In this session we covered several 3D creation tools to create curving surfaces, projecting object to these surfaces, using contours to create a new object, and creating accurate production drawings from a 3D object.

# 3D Modeling Special Interest Group – April 2016 (am)

In this session we looked at various ways to create a bath object using several different 3D tool and commands, then we applied some of the same tools to creating a 3D Bookcase, finally converting it into an Auto Hybrid.

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.

# cadmovie1604_11 – Subdivision Modeling – Part 11

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.

Edge Extend Mode

This mode works mainly with flat subdivision primitives such as the square, circle, ring, et cetera.

# cadmovie1604_08 – Subdivision Modeling – Part 8

Face Hole Mode

This mode will remove a portion of your subdivision face.

# cadmovie1604_07 – Subdivision Modeling – Part 7

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.

# cadmovie1604_06 – Subdivision Modeling – Part 6

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.

# cadmovie1604_05 – Subdivision Modeling – Part 5

Crease Mode

The Crease mode controls the change in direction between faces of the subdivision surface.

# cadmovie1604_04 – Subdivision Modeling – Part 4

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.

# cadmovie1604_03 – Subdivision Modeling – Part 3

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.

# cadmovie1604_02 – Subdivision Modeling – Part 2

Choosing the Correct Primitive Shape

There are several primitive shapes that you can use to start your subdivision surface. Starting a project with the correct primitive shape will make it easier for you to model. For example, if you want to create something like the bean in Chicago (the image I have used on the cover of this manual), then starting off with a sphere would make it easier than starting off with a square.

# Interactive Workshops April 2016 (1604) – Subdivision Modeling

Subdivision modelling is a new area for Vectorworks. It was introduced it Vectorworks 2016 and it will allow Vectorworks to create extremely complex smooth curving shapes.

Subdivision services have been around for some time as a computer technology, but not implemented in computer programs very often. The subdivision surfacing techniques employed by Vectorworks have been developed by Pixar Inc. and Vectorworks are using their system.
