ISO 10303 is an ISO standard for the computer-interpretable representation and exchange of product manufacturing information.It is an ASCII-based format. [1]: 59 Its official title is: Automation systems and integration — Product data representation and exchange.
The PMI annotation is created on the 3D CAD model, associated to edges and faces, and can be exported into neutral formats such as ISO 10303 STEP and 3D PDF. This information can then be used by a number of down-stream processes. PMI can be used to generate annotation on a traditional 2D drawing the data.
STEP-file is a widely used [1] data exchange form of STEP. ISO 10303 can represent 3D objects in computer-aided design (CAD) and related information. Due to its ASCII structure, a STEP-file is easy to read, with typically one instance per line. The format of a STEP-file is defined in ISO 10303-21 Clear Text Encoding of the Exchange Structure. [2]
ISO Standards Handbook – Technical drawings, a broad collection of all basic ISO drawing standards Vol.1 Technical drawings in general, ISBN 92-67-10370-9; Vol.2 Mechanical engineering drawings, construction drawings, drawing equipment, ISBN 92-67-10371-7; ISO 128 Technical drawings—General principles of presentation
FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. [4] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...
ASME Y14.41 is a standard published by American Society of Mechanical Engineers (ASME) which establishes requirements and reference documents applicable to the preparation and revision of digital product definition data (also known as model-based definition), which pertains to CAD software and those who use CAD software to create the product definition within the 3D model.
SolveSpace is a free and open-source 2D/3D constraint-based parametric computer-aided design (CAD) software that supports basic 2D and 3D constructive solid geometry modeling. It is a constraint-based parametric modeler with simple mechanical simulation capabilities. Version 2.1 and onward runs on Windows, Linux and macOS.
The metric drawing sizes correspond to international paper sizes. These developed further refinements in the second half of the twentieth century, when photocopying became cheap. Engineering drawings could be readily doubled (or halved) in size and put on the next larger (or, respectively, smaller) size of paper with no waste of space.
