Geometry creation

Creating the geometry can now begin. We have the referenced sketches within the project and will start to create profiles of the spaces to the building the extrude masses for adding finer detail for modification. Adding information to these masses such as levels will also be covered.

Before

After

Steps:
1. Open file ‘01 Part 4_B’.
    a. Create layers to associate the images and building footprint DWG to maintain a clean environment for before modelling the building masses.
    b. Select the dialog box for layers an select the plus symbol. This will then create a layer. Then can then be renamed: Building Footprint, Elevations
    c. These imported elements can be assigned to the layers by selecting each and selecting the correct layer drop-down list within the dialog box for layers.

2.  Creating the forms
    a. Select shortcut ZT for the top view of the environment
    b. Start creating the surfaces to each space by selecting the 3D sketching tools.
    c. Select the default 3D view (ZD) to make sure you are happy with the created geometry.
    d. Make further modification within the 3D view for referencing to the images imported.

3.  Object profile and extrusions for removal of 3D mass
    a. Select the 3D sketch line tool for modelling on the surface of the mass.
    b. When the start of the line has been specified the angle and direction can be decided for desired direction, by selecting the opposite vertical edge to the mass the line will for a profile for the slope of the roof.
    c. Select the small triangle surface and push this to the opposite side of the mass, this will then remove the excess not required.
    d. Make further refinements to the masses to reflect the geometry references within the imported images.
    e. By double left clicking on the mass it will select the whole object. This can then be assigned for levels which we created at the beginning of this tutorial. Navigating to the properties dialog box you will see a tick box for ‘Use levels’. Select this and the levels create will be automatically applied to the building mass we have created.
    f. This will then feedback the Gross Area total.
    g. Click Save

Summary
This activity covered the process to start building your 3D masses of referenced images to provide a design option of this project. It has enabled the designer to add further details to the object after the main form has been developed. Further details were covered for adjusting and modifying these forms to suit the desired profiles. We concluded the activity with how to assign levels and access the useful data to get feedback on the current design.
