The built-in load calculation tool for Revit MEP is based on the US ASHRAE load calculation standard using thermal balance method (HB) and Radiation Time series (RTS) for load calculations. The tool can automatically identify the building model information, read the area of the building components, volume and other data and calculate. Basic settings 1.1. LocationLocation information is used to determine the latitude and longitude of the

The number of elements in the document is different from that in the view. For example, even if a wall is not drawn, it also contains 6 walls. Using System; Using System. Collections.

At the invitation of the chat group, I gave a lecture on Bim secondary development in the group at on January 1, October 11. Since the participants are basically from the design institute and the construction unit, they gave an overview of revit secondary development and explained revit secondary development in a way that non-programmers can understand.This allows industry leaders or owners to understand t

Although revit users and development are currently rare in China, this is a trend. In the future, revit will replace AUTOCAD in many ways. The Secondary Development of CAD is also very popular in China. However, using C ++ makes it hard for many people. The Secondary Development of revit can use C # And it is very easy to get started. Assume that you are a C

In Revitapi, the method of creating a model line is not in the class Modelcurve itself, which is a common confusion with APIs, and does not know where to use the interface. This can only be accumulated through experience.The API for creating model lines is: Autodesk.Revit.Creation.NewModelCurve Public Modelcurve Newmodelcurve ( Curve geometrycurve, sketchplane sketchplane ) Model Curve has 5 kinds of types, through the input corresponding Curve can get different modelcurve.

I want to create a wall on a skewed face. Is there any sample code for reference? Jeremy has a simple piece of code here. The object document is a project that contains a Conceptual Mass Family instance. The code first retrieves the faces (-1, 0, 1) in the normal direction of the conceptual block, and then creates a wall on this surface. [Csharp] void CreateFaceWall (Document doc) {FilteredElementCollector collector = new FilteredElementCollector (doc); FamilyInstance fi = collector. ofClass (ty

Due to the version problem of Revit, the code for the generated wall element found on the web, compiled in Revit 2016 on my machine, was not able to pass through multiple debugs and finally found the code to generate the wall elements using the API in Revit 2016, which is now posted.The following code is passed in the context of

Revit software can export model data to SQL Server database, sometimes, in order to do data analysis of the model, you need to export the data of the model, the following summarizes the export process:First set up a database in SQL Server, such as: Revit_wujinqianFirst step: Revit Click Export-ODBC DatabaseStep Two: Machine data source-newStep three: User data source (select System data source also)--NextFo

"parameter" of " family type" is divided into "two types": " family parameter ", "Shared parameter", "" "two different parameter data": type parameter, instance parameter. 】The family parameter of the family category is the placement behavior and the component properties of the various artifacts.
