Abstract: We present in this article a compression system that uses STEP compliant standards for the compression and design review visualization of large CAD data sets. Our approach is orthogonal to the traditional techniques applied in the field, as we complement previous works by introducing semantic criteria along with algorithms for the categorization, simplification and user-oriented adaptation of the engineering components described by domain-specific standards. As an example, we have implemented two test cases in two specific domains – ISO-STEP 13013-AP227 in the case of industrial Plant Design, and CIS/2 in the case of Steel Detailing Design (Structures Design).
