Awesome !! it took me ages to understand this stuff by my self.

[@mariyandeveloper8437]

Me too, Alex. The next video will be about dot and cross products in-depth, this one will be really huge!)

Question, when you give a value to a parameter inside the method, you don't need to pass it in as an argument when you use the method ? example : CreateDirectShape( string name = "name") Giving the string a value means you dont have to pass it in when you use the method ?

[@mariyandeveloper8437]

That means you a have default value for the parameter called name, and its value equals to "name". Now, you can easily omit setting that parameter cuz it has a default value, but if you want, you can set it. Now, it's optional.

Hi thank you. Do you decide to talk about winform and some UI trick??

[@mariyandeveloper8437]

Hi, thank you !) I am using WPF for UI, and yeah, definitely, I will show you how to build some awesome forms) Also, I am creating a couple of courses such as Revit API Mastery, WPF Mastery, Plugin Development, and Dynamo. So stay tuned!)

Hi. I have a question. how can I use NewOpening Method in creation Name space. when I Write using Creation Name Space, my document get error because of same name in Document. thank you

[@mariyandeveloper8437]

NewOpening method is located in Autodesk.Revit.Creation.Document. So you simply need to type: using Autodesk.Revit.Creation.Document; To access the Document from creation namespace you need to use Create property on the Document class from Autodesk.Revit.DB.Document namespace. let's say u have a variable called document that stores the Document class from Autodesk.Revit.DB.Document namespace. To use this method you need to: document.Create.NewOpening()

Great video! I didn't know it was possible to use Point and Line in Direct Shape. I usually use it to create some custom Solid, like the intersection between two elements or some Transform in the Solid. One thing I thought you gonna do in the video is to create a CreateDirectyShape Extension for only one GeometryObject. Something link this: public static DirectShape CreateDirectShape( this Document document, GeometryObject geometryObject, BuiltInCategory builtInCategory = BuiltInCategory.OST_GenericModel) { return CreateDirectShape(document, new List { geometryObject }, builtInCategory); } 🤟

[@mariyandeveloper8437]

Thank you!) I did create an extension method for geometry object, but usually I want to call it from the object like solid, curve and point, if you noticed in all my visualize methods I call the extension method "CreateDirectShape", + not all geometry objects are supported for direct shapes

Thank you very much. Thats great

Hello, do you know how to find point coordinates in some local coordinate system?

[@mariyandeveloper8437]

Hello, let's say that your point has coordinates (110, 110, 110), and the origin of the transform is (100, 100, 100). So you simply need to perform this operation: point - transform.Origin, in this case, would give us (10, 10, 10).

[@zbyszekzbyszek5755]

I tried with that but this actually doesnt work when new local coordiante system is rotated in one or more directions. With Dynamo I could do it easily with mapping coordinate system to new but here with API I can’t do it. Maybe I dont understand Transform because it’s something diffrent than CS in Dynamo.

[@mariyandeveloper8437]

​@@zbyszekzbyszek5755 Transform has a lot of similarities to CS in Dynamo, in terms of characteristics (Basis vectors, origin and so on). you can check out this topic on forum forums.autodesk.com/t5/revit-api-forum/transforming-point-coordinates/td-p/6527728.
