Hi everyone. I’m tryign to change the elevation of multiple MText. The use of that is to assign the elevation in a profile at a specific station to the MText thant contains the station. I currently have the list of MText and the list of elevations but I can’t find a node to change the elevation. I hope you can help me. Thanks. ---

Can you attached example drawing ---

Sure. [PRUEBA\_ALINEAMIENTO\_INICIO.dwg](https://forum.dynamobim.com/uploads/short-url/6Wymdra9TgqGwAkLHxNh2zUYVVM.dwg) (1.4 MB) In that dwg there is an alignment (that contains a profile) and multiple MTexts. Each MText contains an elevation. [labelsConElevacion.dyn](https://forum.dynamobim.com/uploads/short-url/kebz67Gw3mbepHu3fLu2rOOgQ9a.dyn) (27.8 KB) That dyn does this: 1. Gets all the MTexts, reads the contents and converts those string to numbers. 2. Selects a profile from an alignment and get the elevation in the profile at the stations in the MTexts. What I need now is to assign those elevation to the MTexts. Thanks for your response. I will be eager to respond to anything else. Thanks again. ---

The Z position of a MText object is set with a Point3d as the Location property. Between Dynamo and AutoCAD the Point3d object is not handled well so a bit of python helps. ```python import clr clr.AddReference('AcDbMgd') from Autodesk.AutoCAD.Geometry import Point3d OUT = [Point3d(p.X, p.Y, IN[1][i]) for i, p in enumerate(IN[0])] ``` (I’ve also cleaned up the text to number parsing) **EDIT** Splitting on the semi-colon is going to be more consistent ![labelsConElevacion_2023-10-19_07-58-15](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/7/a/7a73bb5a27216933f35ca8671f2235997ebfa9d2.png) ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/c/9/c9ec22e1d4812ab2329dfc137415ec8f5c6a68cb.png) ---

I didn’t know that you control the position of a MText with Location. Thank you so much. The Python code works. Can I ask you to explain this part: OUT = [Point3d(p.X, p.Y, IN[1][i]) for i, p in enumerate(IN[0])] Thanks again for your response. ---

Hi Raul, What the code is doing is taking two lists, IN[0] list of Point3ds, and IN[1] list of elevations and building a list of new points. As standard code it might look like this ```python points = [] for i, p in enumerate(IN[0]): point = Point3d(p.X, p.Y, IN[1][i]) points.append(point) ``` `enumerate(IN[0])` gets each item in a list and prepends the index number as a tuple i.e. `(i, Point3d)`. We can unpack this to variables with `i, p` so we can match the item in the second list `IN[1][i]` using the index and at the same time get the X and Y values of the point. ---

Thank you so much for the explanation. I really need to get to learn C3D API and use it in Python. It helps so much with so many things. Thanks again.
