In order to create a dome, first, we have to create two different diameter spheres. For example, if we want to create a sphere, we type "sphere" on the command line and we click on a point that will be the centre of the sphere; next, we have to input a number that represents the sphere's radius or diameter.
If the slicing is done right, we will get the upper halves of the two spheres.
We have the upper halves of the two solid spheres (we have two distinct AutoCAD solid entities). Next, we will use the "subtract" command, which allows us to get only one entity (the "contour") that has a thickness of 0.2 meters.
To convert this AutoCAD entity into an Advance Concrete structural element, we will use the "Convert 3D ACIS solid to structural" function from the "Advance Model" toolbar
After we use the "Convert 3D ACIS solid to structural" function, we select the newly created entity, and, from the drop-down list we must select the structural element type.
Now that we have the dome, we can use it to create reinforcement drawings, sections, elevations, isometric views, etc.
