Siemens NX Jobs

I have a set of existing 3D part models in AutoCAD that now need to live comfortably inside SolidWorks and Siemens NX. The job is strictly Part Design—no assemblies or sheet-metal work—so the focus is on rebuilding each component with clean, fully-parametric feature trees and matching dimensions. You will receive the original AutoCAD files and any supporting notes I have. From there, I need the parts recreated in: • SolidWorks (latest or 2023 format) • Siemens NX (2206 or later) • Neutral STEP files for quick cross-checks Acceptance criteria • Geometry and critical dimensions match the source CAD within ±0.1 mm • All sketches are fully defined; no dangling relations • Feature tree is logically named and ordered for easy edits ...

This tssk focuses on using finite element analysis (FEA) to study the mechanical behaviour of a sugar mill roller shaft under realistic operating conditions. The task requires modelling the shaft in engineering software (NX Nastran) to predict how it deforms and where stresses are concentrated, particularly at critical نقاط where failure is likely due to fatigue. Students must apply appropriate loads (such as roll pressure and torque), define constraints, and choose suitable mesh and element types while justifying all modelling decisions. The analysis is carried out for two scenarios—roll load only, and combined roll load with torque—to compare their effects on stress and deformation. Finally, the results, assumptions, and engineering reasoning must be clearly presented in a st...

I am in the detail-design phase of a new aircraft and need focused help finishing three intertwined tasks: CAD modeling of the airframe, disciplined material selection, and verification through structural analysis. The high-level geometry, aerodynamic data, and load cases are already defined; what remains is turning those inputs into production-ready 3D models and substantiating every spar, skin, and joint. Here is how the work will flow: • CAD modeling – Clean, parametric 3D models of the wing, fuselage, control surfaces, and primary subsystems, ready for downstream manufacturing drawings. Native files in SolidWorks, CATIA, or Siemens NX plus neutral STEP outputs are required. • Material selection – A trade study covering candidate alloys and composites, with just...
