Solid Edge is a key component of the portfolio Velocity Series ™, and has excellent tools for modeling parts and assemblies, design drawings, transparent data management, builtin finite element analysis, which helps to cope with the growing complexity of future product.

New version of Solid Edge ST3 offers enhanced functionality based on synchronous technology, which greatly accelerates the process of product design, easy modification, importation and use of data created in different CAD systems. The latest version includes improvements in the finite element analysis, data management, design, as well as more thousands of changes to specific users.

STEP 7 Professional 2010 - the basic software package, which includes in its membership the tools needed for programming and operation control systems that are based on programmable controllers SIMATIC S7/C7, as well as computer control systems SIMATIC WinAC.

SolidEdge, a core component of the Velocity Series portfolio, is the mostcomplete hybrid 2D/3D CAD system that uses synchronous technology foraccelerated design, faster change, and improved imported reuse. Withsuperior part and assembly modeling, drafting, transparent datamanagement, and built-in finite element analysis, Solid Edge eases thegrowing complexity of product design.

Solid Edge with synchronous technology (Synchronous Technology) - Integrated 2D/3D CAD-item-system without building a tree from Siemens PLM Software s core product line and the Velocity Series. Solid Edge is built on core Parasolid geometric modeling and is compatible with Microsoft Office.
The system provides capabilities for modeling parts and assemblies, creating drawings, design data management and has a built-in finite element analysis (FEA).
Also present in the distribution directory for Standard Parts ST4 (also multilingual).
