Business Needs

  • Extended team of CAD drafter to meet project timelines
  • Skilled resources having expertise in sheet metal designing using Creo
  • Understanding of collision checks for conveyors, slope parameters for waste flow, and space constraints


  • Error-prone and time-consuming design tasks for hoppers as all hoppers are bolted to conveyors and minor changes in location of conveyor in centimeters lead to redesigning of models
  • Management of large assembly input files which sometimes took about 30-45 minutes just to open

Our Solutions & Approach

A systematic approach of building the model met all design guidelines, avoided reworks and saved time in redesigning.

With extensive knowledge of Creo and domain expertise in sheet metal designing, project engineers at Hitech CADD Services learned the design requirements for both walkways and hoppers. Scope of work, plan of action, and milestones were defined to stay on track with delivery timelines, costs and quality standards.

Walkways Output Drawing
  • A team of four engineers studied the input STEP models of plant and assembly models
  • Top-down design approach was adopted to accommodate modifications at later stage as per conveyer location changes
  • RFIs were raised by the project team for quick resolution of queries through calls
  • 3D Parametric models for walkways and hoppers along with 2D manufacturing and installation drawings were developed
  • A quality check by senior engineer was performed to verify that the:
    • Thickness of impacting sheet should be between 3 mm and 5 mm
    • Hopper should have a minimum clearance of 50mm
    • Clashes between hopper and walkway were optimum
    • All details in title block, drawing number etc. were as per the norms

The project head and coordinator ensure delivery of high-quality models and drawings on time through zip files over emails
