MST
MST is a collection of free browser tools to extract BOMs, check data, compare revisions, and reconcile P&ID tags.
MST provides a suite of free browser tools designed to assist with mechanical design tasks such as extracting bills of materials, checking data, comparing revisions, reading title blocks, and reconciling P&ID tags. Users can check line lists against P&ID records, verify delivery packages against local files, compare connection tables, and read tag text. The platform also enables BOM comparisons, BOM-to-model checks, and drawing-to-BOM extractions from PNG, JPEG, or PDF files. Additional capabilities include title block reading and drawing register comparisons. The tools run online in the browser without requiring file uploads or sign-ins for several functions, and the source code is available under an MIT license on GitHub.
