Revit API Development (7): Creating Model Lines

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.

Building Coder (Revit Secondary Development)-create a wall on a skewed Surface

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.

What are the two "family parameters" of Revit?

"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. The use of these components is related to the field of use, namely: the Division of labor related to the various professions (different division of labor uses the same thing)." parameter " of "family
