EXTRA EXERCISE : Seat Section

The second exercise we will be doing aims to refine your 2D Drawing even further. Using the 2D re-shape tool we can produce very accurate traces of scanned in media. If you have a plan, section or elevation of a piece of furniture for example, it is often useful to import into the computer to use as a guide.

1. Import the section jpeg (File>Import>Import Image File). Make sure that the scale is set to 1:20 before doing this. You can draw a line (1300mm) next to the stated dimension in the drawing to check if the section has imported at the correct scale.
2. On a new layer with the 'show other' visability setting selected from Organize>Layer Options, start by drawing in the rectangular base section.
3. Add in a rough polygon shape for the seat section. Make sure that the polygon matches up with the top corner points of the rectangle below. Draw in 4 points around the curved part of the line.
4. Using the 2D Re-shape tool, convert the relevant corner points to bezier control points.
5. Using the Move Polygon handles Mode of the Re-shape Toll. refine the new polyline so that it matches the section underneath.
6. Add in a small polygon for the section between the seat and backrest sections.
7. Repeat the process for the first backrest section. Make sure that the back of the seat stays perfectly vertical and that the points of the polygon line up with the one beneath.
8. Repeat for the top section.
9. Turn the Layer visability settings to 'Active Only' to see the resulting drawing clearly.
10. Add in the back wall section using the rectangle tool. At this stage save your work, make a new layer (Name 3D model), and copy and paste a copy of the complete 2D profile into the new layer.
11. With the profile copy we can now extrude each part individually to the correct length (First go to the left side view, number 4 on the keyboard number keys). Notice that all of the extrusions extrude from x=0.
    
12. In top view (0), select all the extrusions and align using Modify>Align.
13. This is how the seat looks in front elevation
14. Use the 3D Fillet edge tool (Tool sets Palette) to smooth the ends of all the seat sections.
15. Have alook at the model in 3D. Try out a few different types of Render!
    

• Base Section =2400mm
• Seat sections = 2500mm
• Wall Section = 3000mm

Below is how the seat model will look after we have added some glazed panels to the top of the wall and applied a few lights to the scene.



Layer Visibility:
To see other layers whilst in a layer go to Organize >Layer options. Here we can select how to see the other layers (e.g. ‘show others’, ‘gray others’). The other layers are seen but not editable.

Each layer will be shown in its selected orientation, scale and level of render. To align layer orientation go to View >Align Layer Views.

To adjust individual layer visibility go to Organize >Layers, select the layer and click in the relevant visibility column (visible, gray or invisible) .
