Creating volumes from surfaces

The mechanical part to be constructed is composed of two volumes: the volume of the wheel (defined by the profile), and the volume of the axle, which is a prism with an octagonal base that fits into the hole in the wheel. Creating this prism will be the first step of this stage. It willl be created in a new layer that we will name "prism."

Creating the "prism" layer and translating the octagon to this layer

1. In the Layers window, type in the name of the new layer and click New.

2. Select the "prism" layer and click Layer To use to configure it as the activated layer.

3. Choose Lines in the Entities menu of the Layers window. Select the lines that define the octagon. Press ESC to conclude the selection.
