these posts that relate to the 3D Special Interest Group sessions. In these sessions we look at 3-D modelling problems and how to solve them. These sessions are ideal for set designers, exhibit designers, architects, landscapers, and anyone interested in 3-D modelling.
In this session the users want to look at a couple of things. The first thing they wanted to look at was how to make a 3D symbol of a refrigerator read better in elevation and perspective. This involved editing a symbol that was already created, and the symbol also had 2D and 3D components to it. We also looked at creating symbol that was built solely out of 3-D information and how we could ensure that in plain view it looked correct using Auto-hybrid.
In this session the users wanted to look at a stair that had non-standard treads on the lowest two steps. They wanted the steps to fair out at the bottom and they wanted a newel post at the end of the standard handrail.
In this session we looked at replicating a sink unit from a web site. This can be done if you think about the slab as one object and the bowl as a separate object that you subtract from the slab. The trick then is to create the two objects, subtract one from the other, then edit the slab and fillet the edges to create a reasonable model . The second part of the session looked at a bar in a house. This was created using a combination of 3D tools (Extrusion, Taper Face, Push/Pull, Subtract Solid, etc.).
In this session we looked at creating a bar for a nightclub. This allowed use to look at Extrude Along Path…, Extract tool, Create Surface Array…, Convert to Line Light, and we added lights and rendered the screen. This session suffered from sound issues and a major crash that meant that I had to recreate the model.
In this session the attendees wanted to look at modeling a simple greenhouse (Glasshouse). This project is reasonably straightforward and requires the understanding of some 3-D tools and commands. For example, the command used most to create this object is Extrude Along Path… This command is extremely useful for creating objects that follow a path shape.
At the start of the movie this command is covered in detail, using an example that has been troubling one of the attendees (the capping on a balustrade). This part of the movie is useful because it explains the concept behind Extrude along Path. After this we start creating a greenhouse using Extrude along Path, the Push/Pull tool, and the Move By Points tool to create duplicate objects. Another useful technique covered in this movie is the Automatic Working Planes. This concept needs some explanation, so we briefly covered what is the difference between screen plane, layer plane, and working plane.
In this session we looked at as many of the standard tools on the 3D Modelling toolset. Many users do not know what the tools can be used for, so this is the first session (of several) that will look at the tools in detail.
In this session we looked at a commands called Create Drape Surface. This command can be used to create a surface that covered objects, you can often use this to create a smooth copy of a site model. When you use it it looks like you have thrown a blanket over an object. We also looked at creating a simple shade sail, how that could be made thicker, and how you can extrude objects to match the sun shade. The session was cut short by a power failure.
In this session we looked at using simple 3D modelling to create a design to earthquake strengthening. This would be a useful strategy when you want to discuss the design of the detail with an person (maybe the engineer who designed it). Using Automatic Working Planes, simple extrusions, the Push/Pull tool, color to differentiate old and new parts of the design, Fillet Edge tool, Add Solid, and Subtract Solid, we can create a complex detail to show the implications of the design.
In this session we looked at the Clip Cube, how to activate it, how to manipulate it, how to use it to create a section viewport, and how it can be saved as part of a Saved View. Then we looked at creating a 3D detail showing the intersection of a wall and roof. We looked at how to create a wall with cladding and structure, a roof with cladding and structure.
In this session we looked at how you can use Automatic working planes and 3D symbols to make the symbols site directly on the working plane. We also looked at how to start with modelling a sink, looking at the workflow for creating a complex object. In order to create the sink we used the Fillet Edge tool, Taper Face, Shell Solid, Move 3D. When the sink is created, it can be made into a symbol to make it easy to repeat and easy to locate in the Resource Browser.
In the special interest group we had a couple of users who like using SketchUp for 3D modelling rather than Vectorworks, so we looked at how to use Vectorworks for 3D modelling in the same ways that SketchUp does it. I don’t use SketchUp for 3D modelling because I like Vectorworks and I find it very powerful, but I wanted to help people who don’t use Vectorworks for 3D modelling understand how quickly you could create a garden setting.
The idea behind the special interest group sessions is to look at one of the really fun part of Vectorworks, modelling in 3D. But it’s easy to create three-dimensional objects in Vectorworks that you can’t then translate into Vectorworks architectural objects (walls, roofs, etc). In the session we look at a couple of strategies for taking your conceptual model and moving it into detailed Vectorworks objects.
Commands in detail – Extrude Along Path (EAP). The session decided that it would be a good idea to look at one particular command (Extrude Along Path) in detail to see what works and what doesn’t work, to see where you need to be careful and see where we can find a substitute.
Back to basics with this session. I often use a lot of 3D modelling techniques because I find them very efficient when it comes to creating my drawings. But sometimes I think that beginners get lost with my 3D modelling. In this session I decided to go back to basics and show why I think it’s important to use 3D modelling.
