# Dataset Card for TechMB
## Dataset Details
The Technical drawing for Manufacturability Benchmark (TechMB) gives a domain specific benchmark for the task of manufacturability evaluations based on technical drawings.
This task is described as a Visual Question Answering (VQA) task targeted at Vision Language Models (VLM) consisting of 947 question-answer pairs on 180 distinct techical drawings.
The objects, the technical drawings are developed from, represent a selection of parts of the [Fusion 360 Gallery Segmentation Dataset](https://github.com/AutodeskAILab/Fusion360GalleryDataset/tree/master).
Please refer to [their publication](https://doi.org/10.48550/arXiv.2104.00706) for further information. Their licence statement can be found [here](https://github.com/AutodeskAILab/Fusion360GalleryDataset/blob/master/LICENSE.md).
The IDs of the parts from the f360 segmentation dataset also declare the corresponding technical drawings for better association.

## Dataset Structure
The dataset consists contains the following fields:
- **task_id:** ID of the specific question.
- **eval_type:** Classifier for the expected answer type (answer matching or multiple choice).
- **drw_id:** ID of the part and the corresponding drawing.
- **image:** Bit64 encoded image of the exported technical drawing.
- **drw_complexity:** Numeric complexity of the drawing. Calculated with the following formula: $complexity=(faces+dimensionings+\frac{annotation characters}{4.6})*views$
- **question:** The question text.
- **answer:** The expected answer corresponding to the answer type.
- **label_confidence:** The confidence of the assorted labels in manual labelling (low, medium, high).
