Guys,

I'm trying to use the 'NewSpotCoordinate' function in python, but there's an error.

First, I used this code 'Document.NewSpotCoordinate(revit.active_view, ref, point, bend, end, tempArr, hasleader)'

However, an error with the contents 'NewSpotCoordinate() takes exactly 8 arguments (7 given)' occurred.

So I put anything in to make eight parameters. an error with the contents 'expected Document, got 000 '.

Finally, I put 'document type' in first param. So the error that came out was 'expected Document, got Document'.

Do I have to use the 'Transaction' Class?

I really don't know...... What did I miss?

First: yes, you definitely have to wrap this in a transaction.

You have to wrap any and all database modifications in a transaction.

Secondly: watch out! The Revit API defines two different document classes:

Autodesk.Revit.Creation.Document
Autodesk.Revit.DB.Document

Hence, the weird error message.

The NewSpotCoordinate method belongs to the former:

https://www.revitapidocs.com/2020/c2efc79c-75ff-4505-ef3d-3db94a952227.htm

Now, all should be clear.

Best regards,

Jeremy

Thank for your quick reply.
I was already using 'Autodesk.Revit.Creation.Document / NewSpotCoordinate'.
c_doc is 'from Autodesk.Revit.Creation import Document as c_doc' alias.
And I'm try to transation class but I keep getting errors.

Q1) What is the relationship between view3d and view class?
Q2) Is it okay if view3d goes into the first parameter?
Q3) Is the use of transation class(method) correct?

Q4) ......Also What did I miss?

from Autodesk.Revit.DB import Document 
from Autodesk.Revit.DB import Face 
from Autodesk.Revit.DB import XYZ as revit_xyz

        ref = face
        hasleader = True

        transV = Transaction(__revit__.ActiveUIDocument.Document, 'NewSpotCoordinate')
        transV.Start("new spot coordinate")

            for point in points:

                pointY = point[1]

Q1) What is the relationship between view3d and view class?

View3D is derived from View.

Q2) Is it okay if view3d goes into the first parameter?

Yes.

Q3) Is the use of transation class(method) correct?

Looks fine to me.

Q4) ......Also What did I miss?

No idea.

There was a recent issue on converting a Revit API document to a wrapped object for a zero touch node:

https://thebuildingcoder.typepad.com/blog/2019/08/zero-touch-node-element-wrapper-and-load-from-stream.html#2

Do you need to wrap something somewhere?

Re: NewSpotCoordinate in python

jeremytammik — Tue, 29 Oct 2019 07:56:49 GMT

Maybe you cannot create a spot elevation in a 3D view.

Maybe you must be in an elevation view, like in this example:

https://thebuildingcoder.typepad.com/blog/2010/01/spot-elevation-creation-on-top-of-beam.html

You should always test that what you are trying to do is possible at all in the user interface before trying to attack it programmatically.

Thank for your quick reply, jeremytammik

But, I want to use 'NewSpotCoordinate' method.... not 'NewSpotElevation' method....!

Is they the same function?
