Mechanical CAD drawings from your ductwork and pipework mark-ups

Provide your ductwork, pipework or plant-layout mark-ups and the source drawing. We update the CAD to the supplied design and record uncertainties before they become drawing assumptions.

Routing needs context

Levels, sizes, flow arrows, access zones and connections should be explicit. Include sections and relevant architectural backgrounds when a plan alone cannot explain the change.

Production and review

The drafting team records production time separately from checking. The mechanical reviewer checks the marked-up changes, revision, plotting and output pack before the customer proof.

How the drawing moves forward

  1. Upload the matching CAD, marked-up PDF and project references.
  2. Review the estimate and accept the confirmed scope.
  3. Track drafting and respond to logged queries online.
  4. Review the checked proof, approve it and pay before final release.

Questions before you upload

Will the service verify installation clearances?

Only where adequate design and coordination information is supplied and the check is explicitly within the agreed scope. CAD production does not establish site conditions.
