[bharat.minocha]

Did anyone else also encountered this issue while Changing TypeId using method ChangeTypeId being retured with a warning as shown below:

And at the same time if i change the engine it’ll execute perfectly, Weird??
so finally here if someone also bumped into the same, even found a unresolved thread as well seem quite old.

CPython3 and Element.ChangeTypeId

Hi, In IronPython i used the following code to change an elementtype: InGridList[NX].ChangeTypeId(RDB.ElementId(InGridType.Id)) This works fine no problems. RDB for me is: import Autodesk.Revit.DB as RDB, NX in an index number to list. In Cpython3 I get the following errormassage: “No method matches given arguments for ChangeTypeId” The API in not changed so the method most be there. I added “RDB.ElementId(…)” to be sure the given type is an ElementId The element i am working with is a …

Hi,

Chagetypeid() not working in CPython

Hi, I’m trying to write up a python code where I can change element type(wall, stairs, etc.), but I’m having issue with the changetypeid() API because it’s not working in CPython. I found this issue has been there for a long time but looks like it’s not resolved. (TypeError: No method matches given arguments for · Issue #2850 · DynamoDS/DynamoRevit · GitHub) Is there a workaround to change type in CPython? The image is showing just a part of a larger script, so I can’t do it with Dynamo nodes…

Here is an example of the function in Cpython

NewFamily=Grid.Create(doc,anycurve)
        if NewFamily:
                GPI = NewFamily.GetType().GetMethod("ChangeTypeId")
                GPI.Invoke(NewFamily, [ElementId(AnyGridType.Id)])

Create new family or existing.
Get the righte Method
Use an Invoke to execute the right methode
It works for me.

Hi @c.poupin & @b.vanderhoeven

@b.vanderhoeven

GPI = NewFamily.GetType().GetMethod("ChangeTypeId")
                GPI.Invoke(NewFamily, [ElementId(AnyGridType.Id)])

This method worked like charm but @c.poupin still curious why the other overload isn’t working the one u mentioned in previous thread, here’s an implementation of it

It’s asking for doc, Icollection and ElementId. All 3 given so what did i miss…??

It’s asking for doc, Icollection and ElementId. All 3 given so what did i miss…??

The second method is an static method

ChangeTypeId Method (Document, ICollection(ElementId), ElementId)

Oh yesssss…!!! @c.poupin Thankyou both the method working perfectly.

i missed that it was static Method, instead i was calling it as an Instance method.

Marked the solution

And glad to have this community.
