Civil 3D, create an alignment (3 lesson)

In the two previous lessons we saw How to import dots y Customize them. Now we want to make an alignment from the points marked as stations.

Create the polyline

For that, we use the polyline command and we use the snap command to the nodes. We go from the initial station to the final one.

Create alignment

For this we say "alignment / create alignment from polyline"

then we touch the polyline and a panel is raised that for now we pay no more attention than to name the alignment. We will call it "Calle Mel Zelaya"

And there my friends have it.

Ah, you want to create a surface?

Right click on surface, new and well you can call "Surface Hugo Chávez"

Now right click on "definition / point groups" and we say that all those points are the ones that make up the surface.

Well, there we continue after I'm confusing composure. Try in the meantime to create profiles from the alignments and on the created surface.

I am a civil engineer and I would like you to please help me with a particular issue such as the calculation of volumes between two surfaces but limited by a rectangle ... that is, in a sector of the land ... and if tables can be presented with the calculation of volumes together with sections where you can see the lines that define the native land and the line where the cut has reached…. Thanks in advance and I look forward to your response soon… ..
    Keep it up… .. Greetings
