AutoCAD Architecture 2019 API Documentation

We need to migrate our tools to AutoCAD Architecture 2019. I see no information on the new API, although it has obviously been modified. Can you share a link? ... Read more →

Entitlement API, Trial Period and Floating License

I had an exciting weekend with ski tours under challenging weather conditions around Oberalppass, Sedrun-Andermatt, skiing on Piz Maler on Friday, piste in a snow storm on Saturday, and climbing Piz Cavradi via the Maighelshuette Sunday morning in splendid conditions, with 50 cm of fresh powder snow for the descent. Here is today's Revit news for you – Trial period, floating license and the Entitlement API – SketchUp Plugin for Grevit – EMEA ADN team meeting in London... Read more →

Framing Cross Section Analyser and REX in Revit 2015

Back in December 2013, I discussed structural cross section analysis, i.e. determination of the cross section profile of beam, columns, braces, etc., and several completely different approaches one can take to achieve that. I also demonstrated how to make use of the powerful functionality provided by the REX toolkit without building the entire add-in on top of the REX framework. By the way, here are some other earlier discussions of REX: The REX SDK Extensions for Revit 2012 REX Content... Read more →

Launching AutoCAD within a Revit Add-in

We looked at the topic of running AutoCAD inside a Revit add-in way back in 2008, in the grey and dusty beginnings of this blog. Many developers have made use of that since then, and the topic is still important for all those who have significant functionality running inside an AutoCAD application and wish to make use of or enhance it by connecting it with their Revit add-in. Therefore, it is about time to dig that out and have a... Read more →

AutoCAD 2010 DWG Export

Today is a public holiday in Neuchâtel, the jeûne fédéral or Federal Fast holiday. I will use that for a hike in the Swiss mountains, that I so sorely neglected and missed this summer.

The ACADVersion enumeration only has options for 2000, 2004, and 2007. In the... Read more →

Roof Eave Cut in AutoCAD Architecture and Revit

Here is a case that is interesting in its own right, or rather two separate cases and a comparison between the two. The issue is the programmatic setting of the roof eave cut property in AutoCAD Architecture and Revit, respectively. One interesting aspect is the similarity and differences between the two solutions. First of all, here is the original question, addressed at ACA: Question: I am having difficulty accessing the edges of a RoofSlab entity. I am programming in C#.... Read more →
