  • Patent number: 12555289
    Abstract: A method and system provide for annotating a computer-aided design (CAD) drawing. Existing drawings are obtained and include annotations and geometries that serve as annotation points. The geometries are extracted and an Autoregressive Transformer model is trained on the extracted geometries and annotations. A new drawing is obtained. First user input selecting a first geometry in the new drawing is received and the first annotation is created. The new geometries are extracted. The Autoregressive Transformer model generates potential new annotation points and annotations. The potential new annotation points are connected to the selected first geometry and fall within a defined spatial boundary. The potential new annotations are displayed in the new drawing and second user input selects one of the potential new annotations to utilize as one or more new annotations.
