Why Use ST-Developer?

1. The Best for Two Decades
   Since 1991, ST-Developer has been the most reliable, best performing, easiest to use, and most broadly supported STEP SDK available. Our latest release, ST-Developer v15 adds an improved ST-Viewer library, a merged AP203/AP214/AP242 library, international character support, big speed and memory boosts, as well as coverage for Visual Studio 2010, 2008, 2005 and VC6, Linux, MacOS X, and more!

2. Build Applications Simply
   The ST-Developer C, C++, and Java libraries cut cost and effort to build, operate and maintain your STEP, IFC, CIS/2 and other tools, translators and databases. Read and write ISO Part 21 text and ISO Part28 XML files, create, search, and manipulate data elements at the finest level of detail. Plus, years of performance tuning in commercial CAD applications means the libraries do it fast!

3. Distribute Applications Easily
   Shipping products built with ST-Developer is easy too. Our royalty-free distribution license keeps the business side simple while our libraries are designed so you won't worry about the technical aspects either!

4. View and Verify Your Data
   ST-Developer includes the award winning ST-Viewer for STEP geometry and topology as well as product structure and assembly information. And for non-geometry data, we include the STEP Part 21 file viewer the STEP Part 28 XML web viewer to quickly browse through the contents of your data sets and see what is happening behind the scenes!

   Custom checkers for AP 203, 209, and 214 test data sets against the rules in the standard plus vendor forum recommended practices. And for the other standards, you get the general checker that interprets EXPRESS rules and works with any AP or EXPRESS schema.

5. Get Your Entire Team Working
   With our project-based licensing you get as many seats as you need to get the job done. Plus the STEP Tools staff will spend up to three days working with your team to jump-start your implementation with setup, integration, or customization for a particular AP. You can even spend the time at the STEP Tools offices getting hands-on guidance!

6. Enjoy The Portability!
   You can see from our many supported platforms that we will be there for you in whatever environment you need.

7. Get Your Answers Quickly
   ST-Developer includes a full set of online reference manuals and tutorials. In addition to the three days with STEP Tools personnel to jump-start your implementation, you get a full year of maintenance updates and support. We also offer training classes at our offices as well as on-site. Classes range from two to four days with intensive hands-on exercises.

8. CAM? CNC? Don't Forget STEP-NC Machine!
   ST-Developer includes a class library for AP 238, but we have already done all of the heavy lifting in STEP-NC Machine with high-level DLLs for building a STEP-NC pipeline to integrate your CAD, CAM, machining, and probing processes.

9. Make It Even Simpler
   We can apply the same in-house technology from STEP-NC Machine to develop high-level interfaces for other APs too. If you need a STEP interface but don't want to worry about the details, contact us to discuss how we can help.
