I am a Mechanical Engineer
I have done 9 projects on Freelancer
1) Catia -Assembly & Simulation of robotic arm
2) SolidWorks -Editing & Assembly of Pill Dispenser & its parts
3) SolidWorks -Design, Assembly, 2d draft & Rendering of Breeding Box for Parrots
4) SolidWorks -Design the mould die for an MS sheet metal ring. Sourced the ring from a local manuft in Bangalore. 2d drafts & 3d model
5) SolidWorks -Design & FEA analysis of the die & punch for a given bathtub. Design calcs done to find the blank holder force & Maximum drawing Force which were used to find parameters of die & punch & sheet metal. Bathtub was modified accordingly.
6) Ansys Apdl -Analysis of 5 structure including an igs file
7) SolidWorks -3d Design with 2d drafts of a Scientific Instrument(soil testing apparatus)
8) Cad Conversion -Won a contest Given raster png file to dxf AutoCad format of req scale & ratio. Used for glass laser cutting
9) SolidWorks -Motion analysis of a Garage door. Researched to formulate equations. Engg design calculations for selectn of spring & motor. Force supplied by torsion spring & torque required by the motor
Used Reverse Engineering module & used sketch tracer module.
So it will be possible to load jpg files into the software & construct 3d surfaces & models
Cad files conversion, so can provide stl,step,igs,pdf,jpg,dwg,,3mf,parasolid,sldprt,catprt etc
3mf,stl,step,igs are 3d printing formats
