Business Needs

  • Identifying the exact design intent from the drawings with information overload and deliver it to shop floor on time
  • Additional resources to accelerate time-consuming process of deriving relevant information


  • Difficulties in reading information such as part details from input sheets and arrange them as per assembly
  • Tight deadlines due to shorter time between input receipt and release of final drawings for manufacturing
  • Shortage of resources that can deliver quality and cost-effective CAD deliverables

Our Solutions & Approach

Streamline metal fabrication with detailed CAD drafting

The client’s customers shared 2D PDF drawing files with BOMs which were given as inputs to Hitech CADD Services’ project engineers. As these files were stuffed with information, the team began by extracting necessary and accurate information.

  • From input drawings, estimation sheets and quotes were developed and shared with the client for approvals
  • Owing to the team’s extensive knowledge in weld structure modeling, initial 3D part models were developed in SolidWorks as per the part list and final 3D steel structure assemblies were created
  • The team followed bottom-up approach for modeling which enabled easy modifications in single part without any significant constraints
  • Any mismatch in part nomenclature or dimensions in BOMs were shared with client in form of a query document
  • All discrepancies were resolved and the suggested inputs were incorporated the next day owing to time zone difference
  • Final steel structure assemblies were verified against the QC checklist for part list and description, closed sketches, collisions and interferences etc. and submitted with the client through secure Dropbox

The entire project was accomplished through a hierarchical model of a senior project engineer leading a team of four design engineers. They successfully delivered high-quality models across the project lifecycle.
