Autodesk Forma helps planning and design teams deliver projects digitally.
00:08
The powerful 3D Sketch mode in Forma lets you create and modify complex shapes,
00:13
so you can design objects such as cantilevered buildings featuring various unique angles.
00:19
After launching a project with ordered data in the 3D Sketch environment,
00:23
start with a Primitive design shape for this exercise.
00:26
To access your primitive shape options, click Primitives from the Design Toolbar in the upper right of the canvas,
00:33
which includes cubes, pyramids, roofs, cylinders, and domes.
00:39
Click the Cube, or use the ALT+B keyboard shortcut, and then drag it to your canvas.
00:45
It’s important to remember that all primitives are watertight with no geometry issues.
00:51
Initially, by default, the cube aligns with the world north.
00:56
However, you have the option to modify this alignment.
00:59
To do this, navigate to the Set Axes option in the Guides and Measurements menu.
01:05
Given this modification will have an impact on the alignment of every structure created at future stages,
01:11
be sure to set the axis widget based on the most suitable angle for the project.
01:15
For this site, use the axis of the surrounding building,
01:19
so that your cube aligns with the axes of the buildings in the vicinity.
01:23
Additionally, you can group this cube by right-clicking it.
01:27
Grouping lets you manipulate that particular geometry without affecting the rest of the design.
01:32
The cube becomes a container with its own local access, initially aligned with the world axis.
01:38
However, you can always adjust this alignment by selecting the Set Local Axes option in the same Guides and Measurements menu.
01:46
Next, extend this primitive cube by selecting a face, and then, from the toolbar, click Extrude Face.
01:53
Repeat the extrusion to create a rectangular prism. In this example, a triangular site is used.
02:00
From the toolbar, select Move.
02:04
Back in the canvas, click and drag different edges of the primitive inwards to create an angular shape.
02:09
Note that, in this instance, the site is positioned on a slope,
02:13
so you can also extrude the bottom face to ensure that it meets the ground at both ends.
02:18
Extruding primitives in Forma is an intuitive process to create basic building blocks for your conceptual designs.
