Alternative Visualization Methods - Part 3

It has been a while since my last blog entry, but works happens, hey?

Creating interesting visualizations in Revit is a hobby of mine and this blog entry will form part of the Alternative Visualization Part 1 and Alternative Visualization Part 2 series. All of these posts focus on what Revit can natively do - Without using any other program, even Dynamo.

"There are no extra pieces in the universe. Everyone is here because he or she has a place to fill, and every piece must fit itself into the big jigsaw puzzle" - Deepak Chopra
The first example evolved from seeing how one can create a puzzle effect visualization to investigating what effects multiple callouts by sketch would have on project file performance. However, lets see how it was created first, before looking at the negatives, shall we?

A puzzle grid was created and callouts by sketch were added using the individual puzzle piece lines as placeholders for the callout boundaries.

Making use of wide detail lines added a bit more depth perception when all pieces were placed on a sheet. The completed image provides quite an interesting result.

The negatives to this method? First of all, it takes a loooong time to set this up. A callout by sketch does not have the functionality to create circles or arcs - Thus a rounding needs to be created by sketching many small straight line segments. Having many of these callouts by sketch drastically affects the projects performance as well.

"The sky takes on shades of orange during sunrise and sunset, the colour that gives you hope that the sun will set only to rise again" - Ram Charan

Can you create a visualization where only a specific area show in hidden lines, and everything else in colour? The short answer is yes.

We will yet again make use of a callout by sketch, but this time a masking region will come into play as well. With a few visibility edits, the border/boundary lines of the callout and masking region was hidden.

The callout view itself was changed to a hidden lines representation, and its boundary hidden as well.

And the end result?

"I love everything that's old - old friends, old times, old manners, old books, old wine" - Oliver Goldsmith
Paging through a friend's printed visualization portfolio I wanted to do the same in Revit. Partly due to the challenge and partly because we need to save some trees.

For this challenge all that was needed was a book family, and some decal images.

Selected 3d views were rendered and saved as image files, and cropped to simulate the image being printed over two pages. Aligning them together was less of a hassle than I initially thought.

However, a strange thing happened when I tried to RayTrace the view - It looked like Revit was cutting through my book.... It could be due to the curvature of the pages or it might be due to something obscure.

None the less, I created a test render of the same view with the latest Enscape version and I was more than just satisfied with the result!

Have a great week, folks!

Creating Terraces in Revit

A level terrace site is often created in Revit using floors and walls. However, there is a better way to do this - After all, we would like to determine the cut and fill, don't we?

The image below depicts the finished terrain, complete with gabions. Let's see how we can achieve this result.

First of all, lets go through the basic setup of our topography. I love reference planes and therefore we need to create vertical and horizontal reference planes to guide us in the section of topography we want to work with. This site will step down 500mm every 1000mm.

You will notice however, that we cannot place toposurface points with different elevations exactly above, or below each other.

An easy fix for this is to move the lower or higher toposurface points with 0.8mm horizontally to create the terrace

 Creating and placing simple gabion families finishes the terrain off nicely.

Have a great week folks!

Revision Numbering: Clearing the Confusion

Revisions per Sheet or Revisions per Project? That is the question.

There is a misconception with Revit's naming convention for revision numbering options. People often believe that if the revision numbering is set to Per Project, all sheets in the project will have the same revisions showing, irrespective if the revision is applicable to a specific sheet or not. This is not the case at all.

As illustrated by the images below: If the revision numbering is set to Per Sheet, when hiding a specific revision on a sheet, all other sequential revision numbers will change to follow one another. 

However, if the revision numbering is set to Per Project, the revision numbers will not change, thus all sheets will remain in the sequence it was issued with the correct revision numbers.

All About BIM Event: What a great turnout!

Yesterday, Modena Design Centres - Cape Town hosted one of their quarterly events called All About BIM. The turnout at this event has exceeded all of our expectations and I would like to personally thank each and every delegate for setting aside some of their valuable time attending this event. I trust that you have learnt a lot, and that we have managed to invigorate your passion for design using Autodesk software.

Below are a few selected photos of the event, which I hope you will enjoy. Special thanks to my colleagues Arlene Whittaker, Mitchel Parsonage, Anria Erasmus, Gary Graham, our Director: Vincent Modena, Wian Wilson and the Modena Group Sales and Marketing Manager: Wendy Schoeman.

Have a great weekend folks!

Piping and Ducting in Basements

Gore Vidal once said: "Overcrowding in the cities is producing a collective madness in which irrational violence flourishes because man needs more space in which to be than the modern city allows."

The population growth in the world poses a huge challenge for designers. Basic psychology: The smaller a space gets, the more constrained, restricted one starts to feel. There are people who love apartment living in NYC. There are people, like me, who just wants to get out of the "concrete jungle". Each to their own, I guess. However, there are certain health risks that designers need to constantly keep in mind; as highlighted in this Atlantic post.

One of the most important considerations for "high-rise living" is fire protection. This has recently been highlighted by the Grenfell Fire - My sincerest condolences to the families and loved ones involved in this tragedy. Now, the topic of high-rise living safety factors are emotive and expansive to say the least; Something which I will leave to the experts.

This Revit Recess entry will focus on Fire Protection in Revit. Often when working on sloping basement levels and the like, one will see piping below on every upper level. This is due to the view range constraints. Now we know that the View Range property is a global change - Thus affecting every area on a floor plan. However: By making use of Plan Regions, this process becomes a lot easier.

Take this as an example: We have a sloping pipe travelling from level 1 to level 2. Adding a plan region to the area where the pipe segment passes through the 2nd level and modifying the view range does not show any change. This is due to the fact that we are working with one pipe segment.

By modifying the default coupling family to become 1mm in thickness, we can split the pipes where it passes through a level (Hint: Reference Planes are great!) By splitting the pipe in two segments, the pipe will behave as we expect it should, once we adjust the plan region's view range.

On level 1, changing the plan region's view range where it should actually only show piping on level 1 as per the image below solves the problem.

Happy? I am.

Have a great weekend folks!
