Both STL and STEP are fairly common CAD/3D model formats and well supported in many programs so it should be not hard to find one that can perform STL to STEP conversion. Below are few choices that can perform this conversion.
Convert Stereolithography CAD file to ISO-10303 STEP product data.
We have found 17 software records in our database eligible for .stl to .step file format conversion.
Microsoft Windows software - convert stl to step on Windows
A popular is 2D and 3D CAD (computer-aided design) and CAE (computer-aided engineering) construction software for Microsoft Windows developed by SolidWorks Corporation.
SolidWorks is distributed in three distributions: Solidworks Premium, Solidworks Professional and SolidWorks Standard.
Convert from stl file
to step file
The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned stl to step. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
CATIA is (Computer Aided Three dimensional Interactive Application) PLM/CAD/CAM/CAE software suite used to create virtual 3D models, developed by Dassault Systèmes S.A. for Microsoft Windows. CATIA is written in the Fortran and C programming languages.
CATIA delivers the unique ability not only to model any product, but to do so in the context of its real-life behavior: design in the age of experience. Systems architects, engineers, designers and all contributors can define, imagine and shape the connected world.
