IDA-STEP v4 is a new generation of standards-based tools from LKSoft. Based on international standard ISO 10303 (STEP), IDA-STEP v4 supports viewing and management of various STEP data: 3D/2D models, PCB/PCA, PDM and other data. The component-based IDA-STEP v4 structure provides full customization capabilities and is easily extendable.



May 2012: The free IDA-STEP Viewer Basic reached 100 000 installations.

IDA-STEP sold to DCT

In 2019 LKSoftWare GmbH sold IDA-STEP to DCT Co., Ltd. in Tianjin, China. From 2020 on IDA-STEP will only be available from DCT. The free version of IDA-STEP will continue to exist.

Version 4.6 released

Main focus for the 4.6. release are many small improvements around 3D model handling and GD&T editing such as antialising, free text annotations, sections, For the full list of improvements see IDA-STEP v4.6.

STEP AP242 "Managed Model Based 3D Engineering"

With the new version 4.5 IDA-STEP is now supporting the new STEP Application Protocol AP242 Managed Model Based 3D Engineering. AP242 is an upward compatible merger of AP203 and AP214. Once AP242 is finally approved the intention is to withdraw its ancestors AP203 and AP214. Currently AP242 is in the Committee Draft (CD) stage. Testing of data exchange between various CAD-Systems has already started within the CAX-IF.

Significant enhancements for GD&T Editing

The release of IDA-STEP v4.4.2 contains many enhancements for editing of Geometric Dimensioning and Tolerancing (GD&T) directly on a given 3D model.

Release of the new IDA-STEP GD&T Editor

The GD&T Editor allows users to create and edit annotated 3D solid models, eliminating the need for 2D drawings.  This is a huge leap forward, increasing quality and reducing the time needed to encode GD&T requirements. GD&T created by the IDA-STEP™ GD&T Editor is fully-associative; the specifications are visually and logically related to the features they control.

Significant performance increase

The new maintenance release v 4.3.4 of IDA-STEP includes a new, considerably faster 3D visualization engine for all components. Instead of the formerly used Java3D API the new version uses a direct low level OpenGL interface (LWJGL), which results in much less memory consumption. For complex designs memory use decreased up to one tenth (1/10). In addition styling capabilities and others were further improved.
