Hello,
I'm working on a PythonPart (Allplan 2026) that generates elevation and section views on a user-defined structural grid. Each view is created by building a NemAll_Python_BasisElements.ViewSectionElement with a custom ClippingPath and SectionGeneralProperties, then passing it to:
pythonAllplanBaseElements.CreateSectionsAndViews(doc, matrix, elements, [view], vwp)
This works well for the geometry and labeling. However, every generated UVS automatically receives two default horizontal dimension lines (the outer bounding-box dimensions).
In the "Modify section" dialog I can change the Dimensioning setting to OFF manually (the first of the four radio icons in the Dimensioning row — OFF / Normal / Elevation / Rules). For my use case (architectural elevation drawings on a precast context) I would like to have this set to OFF from the start, at creation time, without post-processing.
I've tried the following approaches from Python, all unsuccessful:

Setting view.DimensionElements = [] before CreateSectionsAndViews — the assignment is accepted but the engine repopulates the list anyway.
Setting view.SectionDefinitionData.DefinitionProperties = NemAll_Python_Precast.DimensioningProperties() — raises ArgumentError: the property only accepts UVS_SectionDefinitionProperties, which doesn't appear to be exposed to Python.
Assigning view.DimensioningProps = dim_props as a free Python attribute — silently accepted but not read by the engine.
Using NemAll_Python_Precast.View / ViewProperties / DimensioningProperties: these classes exist in the API stubs but I couldn't find any example (inside PythonPartsFramework, PythonPartsScripts, or the shipped Reinforcement scripts) that uses them to configure dimensioning on a UVS created via CreateSectionsAndViews.

Is there a supported way to:

(a) Set the Dimensioning radio to OFF at creation time?
(b) Alternatively, pass a Precast.ViewProperties with DimensioningProperties.Rules = [] to CreateSectionsAndViews or to the ViewSectionElement?
(c) Or — if the above is not yet exposed — any recommended workaround besides deleting the generated DimensionLineElement objects post-creation?

Any guidance would be very appreciated. Thanks.
