Finally!!! After creating at least one solid in the model, it must be marked as a final result, that is, expose this solid so that it can be effectively drawn in the project.
It is possible to expose one or more solids in the same model. This means that you can create a manhole, where the chimney can be a concrete pipe, the body of the well can be in masonry and reinforced concrete slabs. These differences can be shown in the project with different styles for each component.
You can also expose curves, to make more specific plan representations, for example, draw an outer contour for gutters, because the scale representation is poor.
Blocks can also be exposed, for cases where the point device can be represented by several different blocks, depending on some property
The exposition tools are:
Expose Solid - exposes the 3D solid so that it is drawn in AutoCAD model space
Expose Curve - exposes a curve to be drawn in AutoCAD model space
Connector - creates a point that indicates where other devices can connect to the current device
Block - inserts a block into an arbitrary coordinate system
