Side View of a #Peripteral (#Sexastyle) #Colonnade with #IonicColumns arranged in #Eustyle #intercolumniation. In my previous post at https://pixelfed.social/p/Splines/803076419096100108, I mentioned that the consensus sweet spot for inter-column spacing was 2.25 diameters (4.5µ) between column shafts at the bottom (6.5µ axis-to-axis), except for the two middle columns where the spacing was 3 column diameters (8µ from axis-to-axis). This variable intercolumniation is only for #colonnades in the front and back. The spacing between columns on the sides is uniform as shown in the image here. Something worth noting in this image is the number of columns on each side. In a peripteral (sexastyle) building, there are 6 columns in the front (and back) with 5 intercolumniations between them. On the sides, it is an error to double the number of columns on the sides. Instead, the number of intercolumniations is doubled — in this case from 5 to 10, giving us 11 columns. So, the number of columns is always even in the front, and always odd on the sides (one less than twice the number of columns in the front). On the topic of even and odd, also note that the number of steps leading up to the base of the colonnade is always odd. #Vitruvious suggested keeping the rise between 9" - 12" and the run twice that, or between 18" - 24". Note that these measurements are in physical units — a marked departure from the abstract µ = 144 units we have been using all along. The rules for intercolumniation presented so far are known as #simpleIntercolumniation. When the Romans introduced #arches and combined them with #halfColumns to produce #arcades, the rules were adapted for the new design. Because the arches distributed the load from the beams above, it allowed for wider intercolumniation. With the addition of #pedestals, the gap was made even wider still, and the look of the complete edifice is just majestic! With half-columns and arches, we will see some new architectural elements.
There are two variations of the #IonicEntablature. The classic variation has #dentils, which are teeth-like structures shown here above the #frieze. The modern version has #modillions, which are projecting brackets under the #corona of the #cornice. Well, "modern" is a relative term. For designs that are more than 2000 years old, even an alteration 1000 years ago would qualify as modern. Although the sketch shows the #entablature with a square footprint, in practice, it runs the entire length of a #colonnade (multiple columns) or an #arcade (multiple arches). #CAD construction of the entablature is very similar to that of a #pedestal. The first step is to consult #Vignola's #RegolaArchitettura for the visual appearance, and then consult #Scarlata's #PracticalArchitecture for #VignolaProportions in tabular form. It is convenient to create a spreadsheet to convert the measurements given in Scarlata's book from module "parts" to your own model units based on your choice of value for the module parameter µ. Armed with these measurements, it is time to plot the points and draw the #primaryProfileCurves on our standard 2D grid with minor grid lines 8 units apart and major grid lines 32 units apart. In the first pass, skip the dentils and draw the profile curves for the rest of the moldings. Just as with the pedestal, I will show the macro-level plan as well as the detail plan. So, you don't have to go to Scarlata's book, but you know it's there if you want to. I will show the dentil arrangement in a subsequent post. Based on µ = 144, the classic Ionic entablature is 648 units (36 parts, or 4.5*µ) tall. Of this, the #architrave at the bottom is 180 units (10 parts, or 1.25*µ) tall, the frieze in the middle is 216 units (12 parts, or 1.5*µ) tall, and the cornice at the top is 252 units (14 parts, or 1.75*µ) tall.

Soffit and fascia can be prone to issues compromising your property's overall value and integrity. One of the most frequent issues brought on by blocked gutters or insufficient ventilation is water damage. Accumulated water seeps into the wood and causes rooting and deterioration. Heavy rains, strong winds, and extreme temperatures also contribute to the gradual breakdown of soffit and fascia. For instance, ice dams form at the edge of the roofing system during winter months. If fascia boards are not properly…
Can any French speakers tell if this was a former painter-decorator/sign painter, or a supplier to the trade?

I don't have any location details, but I do like the A.B.C. initials on this fading fascia that was briefly revealed in 2016.

Take some time for pandiculations and, you know, moving in general.
This video about fascia is informative. It also contains images of cadavers. It's only 5 minutes and could change the way you think about your body!
