landscape_nov_16_pm

This entire session was devoted to solving the problem of how to create a landscape feature that was designed to be a series of different sized umbrellas. In order to achieve this we used a subdivision surface for the shape of the umbrella, simply extrusions for some parts of the design, textures for transparency, And we copied, rotated, and resized umbrellas to suit the design.

3D Modeling Special Interest Group – September 2016

3dmodel_029_sept_16

In this session we looked at what is new in Vectorworks 2017 in relation to 3D modeling, focusing on Subdivision Modeling and Camera Match. Vectorworks 2017 now includes Camera Match and Renderworks. Subdivision Modeling has been substantially improved with the inclusion of some new modes.

Topices Covered:
  • 00:00   Why you can’t use a site model to create a playground mound with a tunnel in it, but you can use a Subdivision object to do this
  • 00:49  Using a subdivision (circle) to create the mound, starting with a circle, extending the edges, then extending the mound up
  • 02:53   Adding a sun (heilodon) to see the mound more clearly
  • 03:16   Creating a hole in the subdivision using an extruded circle which can be subtracted from the subdivision mound
  • 05:25   Use a copy of the hole to create a pipe tunnel using shell solid
  • 06:19   Using the Split tool to cut the pipe to match the mound
  • 07:53   Editing the subdivision to change the form of the mound
  • 08:49   Editing the crease of the mound to smooth out the edges of the mound
  • 09:49   Editing the solid section to adjust the cut ends of the tunnel
  • 10:51   Adding a grass texture to the mound and a concrete texture to the pipe
  • 12:53   Creating a suspension bridge for the playground using posts (extrusions) rope (extrude along path) and wooden panels (using duplicate along path)
  • 31:36   Creating multiple viewports quickly
  • 32:09   Editing the mound to make it higher then updating the viewports to see the result

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.

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.

Creating a Shade Sail

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 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.

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.
