Which target you are using (e.g., 3.28 LTR, 3.34+)?
To extract a value at a specific geographical coordinate, use the raster layer's data provider object. from qgis.core import QgsPointXY

to embed U3D into PDF:
district_layer = QgsProject.instance().mapLayersByName("districts")[0] for feature in district_layer.getFeatures(): # Set map extent to feature geometry map_item.zoomToExtent(feature.geometry().boundingBox()) # Update a text label with district name title_label.setText(f"District feature['name']") # Refresh layout layout.refresh() exporter.exportToPdf(f"feature['name'].pdf", settings) Which target you are using (e
Provides UI components like map canvases and layer trees.
It is not a question of choosing one over the other; rather, they serve different stages of the learning curve. to embed U3D into PDF: district_layer = QgsProject
While QGIS 3.x excels at rendering 3D maps within the application (using Qgs3DMapSettings and Qgs3DMapCanvas ), it does not have a built-in "Save as 3D PDF" button. A "PyQGIS programmer’s guide to 3D PDF work" must therefore bridge the gap between QGIS geometry and third-party conversion tools.
