Siemens SiePortal CAx Download Manager
Provider：Siemens
The CAx Download Manager within Siemens' unified SiePortal: STEP/U3D 3D data, wiring diagrams and EPLAN macros for the full industrial range after registration.
At a glance
- Readiness
- L1 · Rigid-body ready
- Rationale
- Product 3D data is supplied as STEP and U3D, together with wiring diagrams, dimension drawings and EPLAN macros, directly usable for cabinet layout and electrical design. Thermal, electromagnetic and mechanical load parameters are not carried in the model, so simulation must be set up separately — hence L1.
- Scale
- SiePortal is the unified platform formed by merging Industry Mall and Industry Online Support, covering selection, purchasing and support for Siemens industrial products, systems and services; the companion Industry Online Support document library is stated at 300,000+ documents. The CAx Download Manager delivers 2D/3D models, wiring diagrams, product certificates and specifications, including EPLAN macros. (The platform positioning and CAx capability are consistent with current official Siemens product literature (for example the LV 18 2026 low-voltage distribution catalogue); the 300,000+ figure comes from official SIRIUS industrial controls material and refers to the total Industry Online Support document count, not to CAD models. Siemens publishes no total downloadable model count, so coverage is described by capability. Checked 2026-10-26.)
- License
- Proprietary but free — The CAx Download Manager is available after registration and is intended for engineering design and documentation of Siemens products. Alongside 3D models it provides manuals, certificates and CAE/CAD data such as EPLAN macros; 3D data is supplied as STEP and U3D. Individual product lines also offer dedicated configurators (for example 3WA/3WL circuit breakers, SIRIUS ACT, 3RM1 motor starters) which return 3D views, CAD data, wiring diagrams and dimension drawings once configuration is complete.

Why it is listed
Siemens has consolidated Industry Mall and Industry Online Support into a single portal, which means the place you select a product is now also the place you download its geometry and documentation. For anyone building a plant or panel twin in a Siemens-centric environment, this is the canonical source, and the CAx Download Manager is the part that turns a catalogue order code into files an engineer can actually open.
Readiness assessment
L1, with an unusually complete documentation bundle. You get product 3D data in STEP and U3D, plus wiring diagrams, dimension drawings, certificates and EPLAN macros — which is more than geometry, and is exactly what electrical and panel design needs. Dedicated configurators for lines such as SIRIUS industrial controls, SENTRON low-voltage distribution and SINAMICS drives return 3D views, CAD data and wiring diagrams for the configured variant.
The limit is familiar: no thermal, electromagnetic or mechanical load parameters travel with the model. A digital twin that needs to compute, rather than merely occupy space, has to be built on top of this geometry.
Practical notes
Register before you start — the CAx Download Manager sits in the support area of SiePortal and is gated on registration. Reach it either from SiePortal directly or through the CAx download manager entry point, then search by article number; the article number is the reliable key, and printed catalogues give per-article links into the product catalogue for this reason.
If a product line has its own configurator, prefer it over the generic catalogue download, because the configured result includes the exact variant wiring diagram and dimension drawing rather than a representative model. Use EPLAN macros when the downstream design is in EPLAN; use STEP when it is in a mechanical CAD system.
