3D Modeling & Production Drawings

3D CAD models and production drawings created from sketches, field measurements, PDFs, legacy drawings, redlines, or existing files.

Service overview

What this service involves

Calicore converts field measurements, sketches, PDFs, legacy 2D files, and marked-up drawings into organized 3D models and production documents. Deliverables are developed around the fabricator’s standards and the intended downstream use.

For existing equipment, the scope can include as-built measurement and configuration documentation. For new work, model review points help resolve interfaces before detailed drawings are released.

Step by step

How the process works

The exact scope is matched to the project, but a typical assignment follows these steps.

  1. 01

    Confirm the intended use and accuracy

    We identify whether the deliverable is for fabrication, estimating, coordination, visualization, or as-built equipment records.

  2. 02

    Collect records or measurements

    Source files, photographs, sketches, legacy drawings, redlines, material information, and accessible field measurements are reviewed.

  3. 03

    Create and check the model

    Parts and assemblies are built with review points for interfaces, dimensions, drawing standards, and conditions that cannot be measured directly.

  4. 04

    Issue production documents

    The agreed model, shop drawings, PDFs, DWGs, revision files, or as-built records are organized and delivered.

Review criteria

What production and as-built drawings should communicate

The drawing must state the basis and accuracy of the information shown, especially when the model was created from field measurements or incomplete legacy records.

Frequently asked

3D Modeling & Production Drawings questions

Which file formats can you provide?+

Native SolidWorks files and common exchange or drawing formats can be provided based on the project team’s software and fabrication needs.

Can you visit the site to measure existing equipment?+

Yes, where location and access make field measurement practical. The required accuracy and inaccessible features are documented.
