Drawings
Redline to CAD Conversion
Field markups and hand sketches converted into production-ready CAD drawings within days.
Drawings
From red ink to permit-ready in days.
When field conditions diverge from the approved drawings, someone has to close the gap before the next submission. We take any form of red-line markup, contractor sketch, RFI response, or site photo and convert it into clean, dimensioned, production-ready CAD drawings formatted to the original drawing set standards. No re-drafting the entire set. No waiting for an in-house drafter. Send us the markups and we send back drawings the building department will accept.
How It Works
Four steps. Clean drawings.
Submit Your Markups
Send us the red-line drawings, field sketches, annotated PDFs, or site photos by email or file share. No specific format required. Include the original drawing files if available.
Scope Confirmation
We review the submitted markups, identify every change required, and confirm the scope with you before production begins. If anything is unclear, we ask before drawing, not after.
CAD Production
Each markup is converted into clean CAD geometry on the appropriate sheet. Dimensions are verified against the markup. New elements are drawn to standard conventions and notation.
Quality Review
Completed sheets are reviewed against the original markups for accuracy and against the original drawing set for coordination. Dimension chains are checked, notation is standardized, and revision clouds are applied.
Delivery
Clean drawings delivered as DWG and PDF. If the project requires permit submission, we format the sheets to the original submission standards with updated revision blocks.
Why This Matters
The gap between what was approved and what was built is not a problem until it is a very expensive one. Inspectors who find conditions that do not match the drawings stop work. Building departments that receive resubmissions with uncoordinated redlines return the package for correction. The cost of clean, accurate drawings at the point of change is a fraction of the cost of a stop-work order, a correction cycle, or a delayed certificate of occupancy. Redlines that sit in a folder are a liability. Redlines converted to CAD are a solved problem.
Source formats we accept
- Hand-drawn red-lines on printed drawings
- Architect's sketch revisions on bond paper
- Contractor markups with field measurements
- Phone photos of site changes
- PDF annotations from any markup tool
- Verbal scope descriptions with site measurements
Deliverables
What you receive.
CAD Conversion
All marked-up elements converted to clean, dimensioned CAD geometry matching the style and standards of the original drawing set.
Dimension Verification
All new dimensions checked for consistency, coordination with adjacent elements, and conformance with the markup intent.
Standard Notation
All new elements annotated to the drawing set's notation standards: materials, finishes, details, and code references as required.
Revision Clouds
Revision clouds and delta markers applied to all changed areas with a revision block update on affected sheets.
DWG Source Files
Editable DWG files delivered along with PDFs so the drawing set can continue to be updated as the project progresses.
Coordination Check
Cross-sheet coordination review confirming that changes on one sheet are reflected on all related sheets.
Who This Is For
Built for these teams.
General Contractors
Converting field change orders, RFI responses, and contractor markups into updated drawings for building department resubmission.
Architects
Outsourcing redline incorporation on projects with heavy construction administration workloads or tight revision turnaround requirements.
Developers
Updating drawing sets after phased scope changes, value engineering decisions, or owner-directed field changes.
Building Owners
Bringing outdated drawing sets up to current conditions before sale, lease, or permit resubmission.
Common Questions
Before you send the files.
- What formats do you accept?
- Anything: hand-drawn red-lines on printed drawings, annotated PDFs, phone photos of field sketches, verbal descriptions with measurements. We work with whatever documentation is available.
- Do you need the original DWG files?
- Preferred but not required. If original files are not available, we can work from the PDF set and reproduce the affected sheets to match the original drawing standards.
- How precise do my red-lines need to be?
- They need to communicate the intent. If a dimension is missing, we will ask. If a detail is unclear, we will flag it before drawing. You do not need to be a drafter to produce usable markups.
- Can you handle large sets with many changes?
- Yes. Large sets with extensive revisions are quoted per sheet or per scope. Send us the set and a summary of the change scope and we will confirm the turnaround and price before you commit.
