Roman Theatre

So I created items O and P  and flew them into blender.
Then I did a boolean on the step and stair units with a cube I created to delineate the part I needed to erase. This created a lot of unneeded faces on the resulting object, but it erased the parts of the steps and stairs that needed to go away.

I thought it was gonna be harder. I thought I might have to go back and edit each stair and step element in Draftsight. That would have been a major pain.

Now on to step 6. The length of the "scaena" ought to be double the diameter of the orchestra.

Double the orchestra is 160'. Cool, got that done earlier. Element 88_scaena, I edited it and closed the thing to box.
The stage height is already set at 5'.

The height of the podium, starting from the level of the stage, is, including the corona and cymatium, one twelfth of the diameter of the orchestra.
The diameter of the orchestra is 80'
Therefore the height will be 80" (oddly enough the height of the average door)

Above the podium, the columns, including their capitals and bases, should have a height of one quarter of the same diameter, and the architraves and ornaments of the columns should be one fifth of their height.
This refers back to this drawing...

The podium is actually the detail slightly smaller than the door height.
It's the protruding detail that the columns set on.
The 1/4 CD is the columns mentioned above.
That means they are 20', now becoming B (not including the 5' podium)
The architraves and ornaments are marked 1/5 B. (4') Essentially the end of this order, above it starting a new one.

So first I will go back to Draftsight, figure out where all columns should be, give them a rough diameter and see what the look like.

So they will start at 11'8' and go up to 31'8".
They're are eight of them.

Using the basic drawing as template, the scaena is 14.5 cm.
the offsets for the eight columns (from the left side) are 4.15, 4.9, 6, 6.7, 7.8, 8.55, 9.7, 10.45

These extrapolated to imperial are 45.79' 54.069 66.207 73.93 86.07, 94.34,107.03,115.31

45 9 1/2, 54 13/16,66 2 1/2,73 11 3/16, 86 7/8, 94 4, 107 3/8, 115 3 3/4
These will be offsets from the left of the scaena. 

Columns appear to be displaced from the wall 0.2cm or 2' 2 1/2"
 For now make the columns 3' diameter

Made some adjustments to the size of columns....for now.

Time to be done for the day........

Even now you can see how the Roman Theatre, improving on the Greek Theatre, is a vast complex, not just seating for a big stage.



view The parapet above, including its cyma and corona, is one half the height of the parapet below. Let the columns above this parapet be one fourth less in height than the columns below, and the architraves and ornaments of these columns one fifth of their height. If the "scaena" is to have three stories, let the uppermost parapet be half the height of the intermediate one, the columns at the top one fourth less high than the intermediate, and the architraves and coronae of these columns one fifth of their height as before.
