Shop Drawing Services

Shop drawings translate an approved design or measured condition into the dimensions, materials, interfaces, and revision information a fabricator or installer needs.

Service overview

What this service involves

Calicore prepares shop and fabrication drawings from sketches, field measurements, design backgrounds, legacy drawings, redlines, or native CAD models. The drawing set is built around the fabricator’s workflow and the project’s required review path.

Deliverables may include part drawings, assemblies, weld or fabrication details, bills of materials, exploded views, installation dimensions, revision clouds, and record changes. Client-supplied design criteria, tolerances, weld procedures, and code requirements are incorporated when provided and approved.

Step by step

How the process works

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

  1. 01

    Define the drawing purpose

    We confirm what must be modeled or documented and whether the files will be used for review, estimating, fabrication, assembly, installation, or maintenance.

  2. 02

    Collect the source information

    Work can begin from sketches, measurements, redlines, PDFs, legacy drawings, existing CAD files, or a written set of requirements.

  3. 03

    Model and review

    We build the parts and assemblies, issue review views, and resolve dimensions, interfaces, materials, and open decisions before final detailing.

  4. 04

    Prepare the drawing package

    Final files are organized for the agreed downstream use and can include native models, PDFs, production drawings, and revision records.

Review criteria

What a useful production drawing must communicate

The required level of detail depends on who will use the drawing and what they must make, assemble, install, or verify from it.

Frequently asked

Shop Drawing Services questions

Can you create shop drawings from field measurements?+

Yes. Calicore can convert measured geometry, photographs, sketches, and interface information into a CAD and drawing package after the source information is reviewed.

Do shop drawings replace engineering design?+

Not automatically. The responsibility for design criteria, calculations, approvals, and professional sealing is defined by the project. Calicore can provide drafting or engineering support within the agreed scope.

Can you revise an existing drawing set?+

Yes. Native files are preferred, but PDFs, redlines, and legacy drawings can be evaluated for conversion or revision work.
