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
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.
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]
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 ...
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.
Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.
