The 2nd Digital Revolution, BIM The first use of the word ‘digital’ in the building industry was with the introduction of CAD. The introduction of CAD brought about great change not only for architectural design, but also overall construction industry which includes aproval and construction. And in an extremely short time. What is noteworthy in this process is that architects has become the protagonist, more than anyone like the permit holder, the ordering party, or the contractors Architects have already taken the lead in introducing ‘digital’ into architecture, and the aforementioned relat ..read more

    Recently I've been asked about how to make a Tetra-Pod with Dynamo. After I created one, I felt it's a quite simple but good example of using geometrical construction in Dynamo, so I'm posting about it.     Basically, the geometry of a Tetra-Pod is from a regular tetrahedron as it's name. So if a regular tetrahedron could be created, making a Tetra-Pod wouldn't be very difficult.     Actually, I've already posted about creating five types of regular polyhedrons a few years ago.(You can read the post here) I've used math to find each nece ..read more

    One of the advantages of using Revit is in making documents. Revit makes it easy for me to create plans, elevations, legends or schedules. But some of elements in Revit models are quite tricky to make it's documents.     Curtain Wall is one of them. It's harder especially when it has curved location line. In Autocad environments, I've naturally drawn a planar for it's documents, but in Revit, I had to use 3d views, assembly or other ways to explain it through documents.     I know there are several Dynamo solutions for unfolding. But I couldn't find a gre ..read more

    When ever I create a Dynamo graph, what I do at the end is reviewing the graph (or python code) and ask myself whether it is the fastest flow. (Yes, I'm a Korean. Click if you want to learn a Korean word pali-pali) There would be a lot of situations though, there are some representative ways to speedup Dynamo. 1. Use Numbers rather than Geometries as possible. figure#1. Geometry.Translate     Figure#1 is a graph to generate 100,000 points by using Geometry.Translate. And it took 2.55 seconds. figure#2. Point.ByCoordinates   ..read more

 Vector is one of the most important factors when you manipulate geometries with Dynamo. If so, Here is a question. What will these two return???     As known, a vector has two factors in it. One is Direction, another is Length. I wondered what does 'Almost' means In Vector.AlmostEqualTo node. There is no 'Almost' kind of things in Math. There are only Right or Wrongs. So, I've tested the node with some vectors which are Almost Equal (for me) to each other to find out what 'Almost' means in the node. 1. Almost Equal Length     As you can see ..read more

 I know this is a rusty issue in Revit community. And There were several opinions about it. But most of them are about view browsing speed or file size. So they were not very useful to speed up my Revit projects. Here is my opinion from my experience that really help you to minimize delay in Revit projects 1. Disable Structure Analysis. Revit calculates structure analysis internally. If your Project is not for Structure calculation, just remove the function from the project. You need two steps to do it.    1st.  Uncheck all of the structure analysis options. Uncheck ..read more

 If you are one of my old subscribers, you may remember one of my old posts which is about Curved Insulation in Revit.  It's 8 years ago and Revit still doesn't provide curved insulation... Really? It's 2021, Musk is going to Mars!! My last insulation family was not bad but not good enough either. This time, I created a Dynamo graph for the same job.  And it's more convenient and better than basic insulation tool in some ways. Is this what you imagine? See below if yes. I created two different Dynamo graph. 1st.  Using Arcs and Straight Lines.  It's creat ..read more

As you know, there are plenty of good solutions to make custom patterns for Autocad. But, if you are really into Revit, there are not many choices. In my case, I've used a solution for Autocad, and used *.pat files from it. I can't say it's very inconvenient, but can't say it great either. I know there are some apps which creates patterns for Revit. They can create pattern directly in Revit. And some of them have a bit complicated options. But I haven't seen below functions from any of them. 1. Non square pattern. 2. Patterns with curves. 3. Honeycomb(hexagonal) pattern. 4. Custom pattern ..read more

It's been quite a long time for me using Revit. When I started to use it, I always had a question that why I can't separate walls and floors from multiple layers in Revit. Because, as an architect, I wanted to use singular compounded wall or floor families for schematic design, then change them as separated ones for D.D and C.D phase. After start using Dynamo, I just thought it could be possible. So I tried to create a code for the job. I'm not sure it's as useful as my thought. but worth to try. After created the code for Walls above, I created another code for Floors here. It w ..read more

Cast-in-Place Concrete is mostly used in construction site in Korea instead of Precast. So calculating Formwork area is one of the most important work at a site. Here is a simple Dynamo code i created. It calculates formwork area and concrete volume of selected zone and export the data to selected excel file. Calculated volume will be more accurate than one from Revit schedule. It joins every unjoined geometries in dynamo before calculation. Actually I haven't been interested in this issue because I'm an architect who works at an office room most of times. I just created the dy ..read more
