The rest of the bases were fairly easy to generate (based on the previous website information given):

I'm only missing the capitals for the ionic, corinthian and composite columns.

Version 1.3.3 - 04.05.2020
- Added a classical column option to the post module: Tuscan, Doric



Once I have capital/base geometry for the three other column types (ionic, corinthian, composite) I will add them to the module as well.

First look at a Doric Column with both the capital and base enabled:



To my knowledge this is the only SketchUp plugin that allows one to parametrically create classical columns, I'm pretty excited about this.

The components utilized for the capital and base are within the components sub-folder of the plugin and can easily be replaced with a users own file if so desired.

For my geometry I've been studying the references and drawings found on this site:

http://theclassicalorders.com/thedoricorder.html

This website has very detailed explanations and drawings of the various orders, which I have found to be extremely helpful.

The Ionic, Corinthian and Composite capitals are very intricate and complex 3D geometries.  I'm not even going to attempt to draw those myself, even though I can program plugins my modeling skills are just not up to par.  I think I can rely on the 3D warehouse and some of you power users to point me in the right direction as to what would be the most accurate and low poly model that I can incorporate into the plugin for each of these orders.

First look at a classical column with the updated menu items:



The diminution/entasis is the correct 5/6 ratio and it follows an arc/curve tangent to the lower cylindrical section of the column.  I've created the arc with eight segments which seems to be more than adequate (could probably get away with six).  I have my own smoothing routine so the tangent edge at the 1/3 point on the column is not shown.

Now I just need to come up with some proper bases and capitals for the different orders and we will have some classical columns available.

I could hollow out the interior but I don't see a big need for that since each manufacturer is going to have their own wall thickness, and it just adds to the overall polycount.  Comments or thoughts?

I suppose I could make the diminution ratio also user driven but for now I'll just hardcode in the 5/6 ratio since this seems to be the most common.

I will provide an additional option called the "classical option".

This will allow for classical (round) columns, the parameters will initially be:

Classical Order: Tuscan, Doric, Ionic, Corinthian, Composite
Diameter: (12" default)
Capital: Yes/No
Base: Yes/No
Material:

At some point I should also provide the option for a fluted column and additional parameters for a pedestal. Yes, this is a bit of a rabbit hole, but really not as deep as initially thought it might be. I'll start simple first and then incrementally add more features as requested.

I'm making the assumption that all of these classical columns are non-structural (ie. FRP) so the standard wood or steel posts will still be drawn/installed inside of the classical column.

For the base and capital of a classical column I think it would be easiest just to pre-model some standard configurations and then have the plugin insert the components rather than try to draw them from scratch.  Since both of these elements are merely a function of the column diameter the plugin can easily scale them to the correct size upon insertion... problem solved.

Now I just need some decent (but low poly) ionic and corinthian capitals, if such a thing is possible. 

I'm always up for a bit of a challenge so after digging around on the internet for awhile and reading some documents provided by some of my mentors here is what I have for classical columns:

1.)  The diminution ratio seems to be 5/6 for most columns that are 15ft of less.  I will label this ratio as "m".

2.)  There is a height to diameter ratio however I think I should leave it up to the user to specify whatever diameter they chose for any particular height however I could suggest the classical (recommended) diameter for a given height.

3.)  If we let the base diameter be "d" then the entasis radial difference "E" is given by:
E = d(1-m)/2.

4.)  Let h = height of the shaft.  The entasis (or diminution) begins at a height of 1/3h.  The entasis is not a linear reduction in diameter but rather follows a curved profile with the radius of curvature tangent to the lower cylindrical portion of the shaft.

5.)  The radius of the entasis curvature is given by r_e = 2h²/9E + E/2.

6.)  The angle of the sweep of the arc is given by theta = asin(2h/3r_e)

The above derivation and observations should then give me enough information to be able to properly draw the shaft of any classical column.  The base and capital however are a whole nother story.

Tutorial 10 - Posts (14:24 min.)



Round or Greek/Roman columns would also be a nice addition to this module but I'm not entirely sure on the construction or geometry of them.  They typically have a gradual taper and then the top (capital) always has some interesting geometry (Doric, Ionic, Corinthian):





If I can figure out the math and right proportions for these types of columns then I can probably add them to the module with minimal effort.

Version 1.3.2b - 04.02.2020
- Added an indexing parameter for posts to the General tab of the global settings.
- Added the built-in materials (red brick) for post wrap and wainscot and (concrete) for post ledges.
- Added labels and callouts for all post types.



I've also switched to the new .rbe encryption method for the plugin which effectively prevents it from running on SketchUp 2015 or earlier.  I was more than content to stick with the .rbs encryption method but the SketchUp extension signing page has removed this encryption method and only the .rbe method is currently offered.

Version 1.3.2 - 03.31.2020
- Added the ability to draw and edit free standing columns with the Beams/Column Toolset.

If I get more requests for this feature I will seriously consider it.  I have added it to the todo list but it is not high priority just yet.

First look at some posts created with the Post module:



The basic module is up and running I just need to spend a few more hours on the advanced options (ie. wrap, wainscot, base, cap and astragal) and then this module will be a welcome addition to the plugin.

Currently the gable and shed wall tool is still in development.

In the meantime you can create a gable wall manually by first creating the wall as a rectangular wall and then once all of your openings and other features are finalized manually editing the wall panel.

See this tutorial video (Gable Wall Workaround) for more details:

Version 1.3.1 - 03.15.2020
- Added a "Style4" door hardware option (Lever & Deadbolt) to the door module.
- Fixed a bug with the door opening tool for man doors.

First look at the HTML draw menu for the Post module:



This module is relatively simple however since there are so many advanced options there is still quite a bit of coding to do.
