AskFeatures

Request

AskFeatures is a request object used to extract features from a technical drawing. Features may include geometric elements, annotations, dimensions, and other key components essential for understanding the drawing.

Example Usage

from werk24 import AskFeatures, read_example_drawing

read_example_drawing([AskFeatures()])

Response

Bases: Response

Represents an Response to a request for features of a mechanical component drawing from the server. It contains extracted features from the technical drawing, providing structured data for further processing.
