I have 6 year experiences in 3D modeling. For more than one and a half years I designed cooling devices and for one and a half year I design structural products for constructions (for example form-work). These products I designed in SolidWorks. When the 3D models are finish and are approved, I make their production drawings. Beside SolidWorks i used Solid Edge for three years in high school. For maturity exam I modeled an old inter-row cultivator with four rows.
