EASM to STEP

About This Tool

Designed for mechanical engineers, CAD technicians, and design coordinators, this tool translates CAD assemblies from EASM to STEP to support cross-software interoperability and downstream analysis. It preserves assembly structure, part instances, and basic geometry, enabling teams to review, simulate, and fabricate designs using STEP-based workflows. The tool accepts EASM files produced by common CAD systems and outputs a STEP file that is standards-compliant and ready for import into CAE, CAM, or PLM pipelines.

Conceptually, the process begins with importing the EASM, constructing an internal representation of the assembly tree, and translating geometry and topology into STEP entities. Depending on the chosen schema (AP203 or AP214), it encodes assembly relationships, part instances, and basic metadata. The translator aims to minimize data loss while producing a portable file, with options to map colors or simple attributes where supported.

Benefits include faster design handoffs, reduced rework, and reliable archival because STEP is widely supported. Typical use cases span supplier exchanges, cross-platform simulations, and long-term digital preservation of complex assemblies. The tool supports batch workflows and per-file schema selection for large product families, making it advantageous for engineering teams managing multiple CAD ecosystems.

Core features include input validation, schema selection, batch processing, color/attribute mapping, and a detailed conversion report. Outputs are a STEP file and a human-readable report that highlights any limitations or data approximations encountered during translation.
