The Building Coder

SVG, In-Memory Family, RevitLookup BoundingBox

The cloud accelerator kept me busy last week, I am working hard on the CompHound project and documenting that work on The 3D Web Coder. Besides that, I submitted several enhancements to various Revit add-in projects. Here are some of my recent activities – CompHound component tracker project development – RevitLookup displays element bounding box – SvgExport for Revit 2016 – In-memory family creation and structural stiffener migration from 2012 to 2016...

RevitLookup in Python Shell and Multi-Release Solution

Here is some exciting news from Daren Thomas on RevitLookup and the Revit Python Shell. The Python and Ruby shells came up a couple of times recently, and I also mentioned Daren's initial thoughts on making the RevitLookup snoop functionality easily accessible from within the interactive Python IDE: Curved wall elevation profile implementation in Python Live development Revit 2016 Python shell and RevitLookup incorporation Revit 2016 Ruby shell This idea has now come to fruition, and more easily than one...

Migrating The Building Coder Samples to Revit 2016

I finally tackled the task of migrating The Building Coder Samples to Revit 2016. I also have another update on RevitLookup to report: Preparation Fixing the compilation errors Installing RvtSamples RevitLookup update displays all built-in parameter names Preparation Before doing anything else, I ensured that the entire project compiles for Revit 2015 with zero warnings. This guarantees that I am not using any API functionality that was already deprecated in Revit 2015 and therefore removed in 2016. I then replaced... Read more →

What's New in the Revit 2016 API

Here is the online version of the 'What's New' section of the Revit 2016 API help file. The information provided here is extracted from the document 'Revit Platform API Changes and Additions.docx' provided with the Revit SDK. As said, is also included in the 'What's New' section in the Revit API help file RevitAPI.chm. This is very important information, even for later reference. The explanation of the changes and enhancements are well worth referring to later on as well, to... Read more →

Re-Researching Lighting Family Instance Placement

The placement of family instances can sometimes be a tricky topic in the Revit API. Programmatically, this is always achieved using the NewFamilyInstance method. However, this method provides 13 different overloads to choose from, which can be a non-trivial task: NewFamilyInstance(Face, Line, FamilySymbol) – Inserts a new instance of a family onto a face of an existing element, using a line on that face for its position, and a type/symbol. NewFamilyInstance(Line, FamilySymbol, View) – Add a line based detail family... Read more →

Picking Pairs and Dimensioning Family Instance Origin

We looked at various aspects of creating dimensioning in the past. There is still one glaring omission, though: how to dimension to a family instance origin point. Let's take a look at that, after quickly mentioning the official announcement of the movie matching game that we created at the recent Berlin hackathon. Actually, coincidentally, I discuss two topics today that are both completely and utterly dedicated to picking pairs: the Movie Match MasterY game, matching pairs of cards representing films,...

Past, Future, Frameworks, RevitLookup and Hackathon

Today, let me ask you to test my RevitLookup future-proofing update and mention a discussion on the use of the .NET 4.5 framework for Revit 2013, 2014 and 2015. I am sitting here writing this among the swans and gulls, squinting in the autumn sunshine on the shore of the Zurich Lake. Later, I visited the nearby Kronenhalle, a rather exclusive restaurant highly praised year in and year out by gourmet Christian Seiler, e.g. 2011, 2012 and 2014. With all... Read more →

ADN Labs Xtra on GitHub and RvtVa3c in Three.js

I had several cases recently discussing advanced Revit API exploration issues with experienced application developers new to the Revit API. Therefore, once again, the topic of available tools and their various uses came up. One important tool for me is the simple element lister, which is currently still part of the ADN Xtra labs, the precursor to the official ADN Revit API training labs. I had not yet migrated those to Revit 2015, so I now finally did so and... Read more →

Setting up a 3D View like a Section View

Lots of add-in developers have struggled with various aspects of setting up cameras and views. I summarised a number of them in two new topic groups: 5.37. Creating and Setting Up a 3D View 5.38. Creating and Setting Up a Section View I keep hoping that they cover everything one needs to know in this area, together with Steve Mycynek's all-encompassing AU class CP3133 Using the Revit Schedule and View APIs. Here is one recent example proving that this sometimes... Read more →

Debugging and Maintaining the Image Relationship

The Revit database contains a number of undocumented relationships, and it can be challenging and useful to discover them. Christian Tonn of kubit presents a powerful method to determine and maintain such a relationship using an officially supported approach instead: Question: Is it possible to get the ImageType object from an image you inserted in the Revit document with Document.Import? Answer: Not directly! I am using the Import method: bool Import( string file, ImageImportOptions options, View view, out Element element);... Read more →

Exploring How to Remove a Shared Parameter Definition

Here is yet another example of the importance of the RevitLookup database exploration tool. In this case, Trevor Taylor of ZGF, Zimmer Gunsul Frasca Architects LLP, shows his use of it to discover how to remove a shared parameter definition. Task at Hand When I remove a shared parameter definition, it disappears from the UI. However, the parameter definition isn't truly removed from the model. Its definition persists. Steps to repeat: In a shared parameter definition file, create a parameter... Read more →

Accessing Extensible Storage on OwnerFamily in Project

A couple of developers reported a problem accessing extensible storage data on families when they are loaded into a project in Revit 2015. This problem did not occur in previous versions. Luckily, a workaround is possible right now, designed and implemented by Alexander Ignatovich, Александр Игнатович, of Investicionnaya Venchurnaya Companiya. Alexander already made a number of other complex and powerful contributions to The Building Coder in the past: Exporting Image and Setting a Default 3D View Orientation Intimate Revit Database...

New Revit 2015 SDK Samples

Rather belatedly, I went through my usual analysis of the Revit SDK to determine the new samples added to the Revit 2015 SDK. While I was at it, I also migrated the DevDays samples for Revit 2015 UR1, since some new SDK functionality is not yet covered by new SDK samples, and the ones posted with the DevDays online recording were still compiled for one of the early pre-release versions of Revit. New Samples in the Revit 2015 SDK To... Read more →

RevitLookup for Revit 2015

My first post dealing with Revit 2015 is dedicated to RevitLookup, the most important Revit database exploration tool, both for developers and interested non-developers. This is particularly urgent, since RevitLookup no longer is included in the standard Revit SDK (software development kit). It is now available from the RevitLookup GitHub repository instead. I created a preliminary version of RevitLookup for the Revit 2015 Meridian pre-release, just to ensure that everybody who needs access to this tool has it available right... Read more →

The GEOM_VISIBILITY_PARAM Visibility Settings

Here is an nice, useful and interesting example of a Revit API forum discussion thread and cooperative research between Remy van den Bor of ICN Solutions, Rudolf Honke of Mensch und Maschine acadGraph, the Revit development team, Joe Ye and your humble scribe on retrieving an element's detail view visibility settings, before wishing you and us all the best for the year of the horse: Remy: Hello Reviteers, Does anybody know how to get to the visibility settings in the...

Lots of Clouds

Let me recapitulate my cloud related explorations for my simplified 2D BIM editor, since I will be discussing it again at a web-based BIM workshop later this week. Before getting to that, though, talking about cloud related topics reminds me of some others of completely different nature that are near and dear to me: Clouds in La Palma Cloud Atlas Cloud-based simplified BIM editor Autodesk cloud service overview Updated RevitLookup on GitHub Above, in and under the Clouds of la...

ExportCncFab on GitHub and RevitLookup Update

I am in a hurry, still not finding time to prepare my AU classes, and lots going on. I published an add-in named ExportWallboard to automatically isolate and export wall parts individually to DXF for CNC fabrication back in March, still for Revit 2013, at the time. That utility is in use, was renamed to ExportCncFab and has enjoyed some further enhancement since, such as: Support for export to SAT as well as DXF A beautiful little external application to...
