Farewell 2018, Hello 2019!

As 2018 is coming to a close and has given us some amazing architecture, engineering and construction projects all over the world, I can only hope that 2019 will up the ante even further.

South Africa has had a number of amazing projects reaching completion in 2018, none of which I will highlight in this post. Why? The reasoning is simple: Only a few of these projects have reached the papers, magazines, blogs and the like. I can promise that, if only looking at my current client base, the sheer amount of quality designs will make choosing the best impossible. Do yourself a favour and Google some AEC inspiration on the "dark continent" 

There is however one project located just outside of Worcester, Western Cape which still amazes me. Bosjes Chapel, designed by Steyn Studio based in London (Coetzee Steyn is a South African by birth after all), completed in 2017. Just have a look at this picture which simply just does not justify physically being there yourself.

As quoted directly from Steyn Studio's website, let the team speak for themselves: 

" The site is surrounded by majestic mountains with a grand scale which adorned the area with the nickname of 'Little Switzerland'. Typically Cape Dutch Manor houses set up dialogue with these types of environments, as found in Stellenbosch and Cape Town. With the immediate context of the site, the valley is 'held' either side with two mountain ranges which sets up a spatial dialogue at a grand scale which occurs on a 'micro' level between the Manor House development node and the Chapel development node; across the vineyards and gardens.

The chapel development reflects, in microcosm, one half of what already exists at the scale of the valley as a whole in terms of its sculptural relationship, as does currently exist between the Manor House and the Waaihoek Mountains. The development profile, architectural form and massing responds sculpturally to the natural configuration of the mountain backdrop. 

Similarly, the text of Psalm 36:7 is also considered as an important informative from a poetic point of view, and its interpretation, architecturally, as a structure which 'floats/glides' and has motion, although physically static. 

In order to achieve the visual 'lightness' of the roof, the structure has to be simple, unifying and as structurally efficient as possible. It was therefore decided that the roof can also become the walls/columns; its own supporting structure. To realize this we investigated parabolic/hyperbolic arches and surfaces; and its use in thin shell concrete structures.

This translated into the sculptural form which emulates the surrounding mountains as well as the poetic motion sought. This lightness & motion is further emphasized by means of the interpretation of the baroque 'holbol' gable in the edge profile and the roof shape. The main characteristic of a 'holbol' gable is that of the combination of outward and inward curvatures which results in a series of 'peaks' and 'valleys' within the roof itself. 

Similar to the Mission Churches it has no vertical elements and the form is generally horizontal. As with the gables present on these churches, the identifying element on the Chapel is that of its roof and its shaped edges. Apart from investigating the local history of the farm we also looked at Moravian Missionary Stations as inspiration. The aim of the chapel is also to reflect the following qualities present in these historic missionary churches of Mamre, Elim and Wupperthal: 
- Utilitarian simplicity of its plan as an assembly space 
- Scale
- Cultural reference 
- Tranquility of its white lut interiors
- 'Tactileness' of its undulating whitewashed walls

However, whereas these churches are mostly inward looking and spiritually reflective, the proposed chapel is to be a more 'open' space which invites in, as well as expands its intimacy to the valley and mountains beyond, raising the awareness of God's creation in the immediate surroundings. " 

 Psalm 36:7 in Afrikaans: "U geregtigheid tot op die hoogste berge, die reg wat U spreek, tot in die dieptes van die see. U sorg vir mens en dier, o Heer"

May all Revit Recess readers have a blessed Christmas and wonderful new year. 2019 will have a number of new and exciting adventures in store for us all.

Stacked Walls: Alternative Uses

Stacked walls are often one of the lesser used functions in Revit. It does have its own pro's and con's, but in this entry, we will look at what one can achieve using stacked walls. This is not necessarily a how-to post, it is more of a "what can we do with stacked walls"  post.

None the less, let's get started

The basic composition of this stacked wall is 9 Generic 600mm walls with a height of 250mm. Stacked walls does however require at least 1 section of variable wall, which forms the 10th piece of wall.

I quite like the fact that due to a stacked wall being just that: a wall, the normal wall editing functionality still applies. Selecting the stacked walls and pressing space bar will flip the walls' orientation.

Editing wall joins only affects the variable layer of the stacked wall.

Wall profile edits will allow you to edit the top and bottom of the stacked wall - Think base and top constraint. Any closed profile sketched inside of the outer profile boundaries will create a cut out.

Attaching the top of the stacked wall to a floor and roof also works. Note that the variable layer only attaches to the roof.

A wall is a wall and thus the typical architectural and structural column behaviour still applies when adding those "through" the wall.

Wall sweeps and reveals can also be added to the stacked wall.

When I tested the updating of the stacked wall to a conceptual mass, I noticed something interesting: The "Update to face" icon in the ribbon wasn't there anymore. Seeing that I was using Revit 2019 for this entry, I noticed that the latter has been replaced with a "Remake" icon in the options bar.

Using stacked walls, we can still host elements on the faces of the wall itself, like wall-based or face-based lighting fixtures.

Have a great week, folks!

Multiple Instances Of One Project Link In A Federated Model

"Anything that is worth teaching can be presented in many different ways. These multiple ways can make use of our multiple intelligences." - Howard Gardner

Imagine working on a project where there are multiple buildings/rooms/spaces which looks exactly the same, but in different locations, elevations or orientations. Many think that each one of those buildings/rooms/spaces must be handled as separate project files, which would then be linked into the Master Project file (Typically the Shared Levels and Grids Project, containing the topography)

However: There is an easier way of doing this

In this example, two buildings were created, each in their own project file. Multiple instances of these buildings were placed in different locations, at different elevations and orientations within a Federated Project file. By entering the Shared Site functionality of a specific link, notice that one can record the position of this linked file's INSTANCE. This is a very important concept to remember. Even though we are working with one file, changing this setting will only affect the selected instance/s.


Notice that we can create multiple positions of the same linked file, thus being able to place multiple instances of the same building in our project, and record those unique positions.

The above becomes quite important when other parties need to work on/with your project. They would link the Topography, and each individual link into their project (In this case we use a Structural Engineering model as an example). When entering the Shared Site functionality, we can control that Building A must be linked into both the Unit A1 and Unit A2 positions. Similarly, Building B must be linked into both the Unit B1 and Unit B2 positions.

Should anything change within the linked files, it will update automatically, retaining the position, elevation and orientation.

Even your schedules, provided that you have entered the correct non-graphical information into your linked files and linked instances, will show the correct information.

Seeing that it is Friday, how about a bit of philosophy?
Irrespective of whether you agree with Howard Gardner's theory at the start of this blog entry or not (Intelligences versus Aptitude versus Personality Traits), I do believe that Education and Training needs to adapt to the ever changing times, industries, atmospheres and technologies.

People's behaviours and perceptions also needs to drastically change. Don't get me wrong, this is not a rant. However, I came across a very thought provoking Ted Ed talk by the former host of Dirty Jobs, Mike Rowe: Learning From Dirty Jobs.

Yes Mike, I got a lot of things wrong too

Revit 2019 - Precast Add-in


"Better Quality, More efficiency, Unbounded Creativity" - blogs.autodesk.com


I recently played around with the Precast Add-in for Revit 2019, and I must say that I had some fun in doing so.

Trying to see if I could "break" the add-in, I created a ring's head using structural walls

These walls were split through the Precast add-in, providing the results below:

Reinforcement was automatically added to each splitted part through the add-in as well

Selecting the Shop Drawings command, Revit generates Assembly views, complete with Sheets and Schedules and places it on each part's sheet. Minor tweaking will need to be done regarding the placement location of the views on the sheets.

Have a great weekend folks!

3D View Manipulation Using Scope Boxes - Revit 2019

Something I do love about new releases of Revit, and even with new Service Pack updates, is that we often find new features which are not part of the official new features lists. Similar to the previous Revit Recess post: Revit 2019 Colorfill Legend Visual Style, we have another exciting new feature which allows us to crop a 3D view with a scope box.

Let's start this entry by looking at the various ways in which we can manipulate the extents of a 3D view:

Method 1: View Crop Region - Pretty much self-explanatory

Method 2: Section Box - A manual method of isolating a specific area of your model, manipulating the section box extents by pushing and pulling the section box sides. The biggest drawback to this method is that the size and position of the section box is not saved. In other words, if you meticulously position and size your section box, turn it off and turn it on again, the section box extents will be around your entire project.

Method 3: Selection Box - My go-to method for automatically sectioning a 3D view according to selected objects. A "Bread-and-Butter" command along with Trim and Align.

Method 4: Scope Box - Revit 2019 now allows us to apply a scope box to a 3D view. This is game changer, especially when working on very large and complex projects, where a lot of time has been spent setting up specific positions for scope boxes on plan views. Very nice feature.

Have a great weekend, folks! For the South African readers of Revit Recess, enjoy Heritage Day on Monday!
