Hello - it's very clear and probably 100% fluent, but I think I'd change 

"for the design of 2D objects and 3D"  (a little clumsy)

to 

"for the design of 2D and 3D objects."

Impressive though - good luck with the job!

Hi! Can anyone help me to write my summary of my resume?

I already wrote this:

Experience in Project Management, Process Simulation, Strategic Planning and Plant Design. Comprehensive view of organizations and their processes. Oriented to management and improvement production processes and services; furthermore to the efficient use of resources, quality and productivity criteria

Intermediate handling of the following tools: Autocad 14; Arena Simulation Software 2014, for the design of models for the simulation of real systems; SolidWorks 2012, for the design of 2D objects and 3D; Visual Basic 6.0 (Basic) Software; Anylogic Simulation 7.0; WinQSB, for Process Optimization (Operations Research).

But I don't know if some parts are really understandable.

Thank you!!
