Single source of truth
Models, drawings, and BOMs live in one versioned workspace. No more hunting across network drives or email threads.
Draft together. Ship with precision.
DraftLine keeps parametric models, BOMs, and design reviews in lockstep — one versioned workspace from first sketch to released drawing.
Built for the whole engineering loop
Every tool your team needs to move a design from concept to controlled release — without leaving the browser.
Precision reviews
Measure, markup, and thread comments directly on geometry. Decisions land next to the features they change.
Parametric grid sync
Constraints, mates, and tolerances stay consistent across edits — conflicts are flagged before anything ships.
From sketch to release in three moves
01
Connect your CAD
Link SolidWorks, Onshape, or STEP files. DraftLine indexes geometry and metadata in minutes.
02
Collaborate live
Invite reviewers to markup models, watch edits land in real time, and resolve threads in context.
03
Release with confidence
Lock revisions, auto-generate drawing sets and BOMs, and ship a fully traceable release package.
Trusted on the shop floor and in the lab
We cut our release cycle from three weeks to four days. Review threads live right on the geometry, so nothing gets lost in email.Mara Chen

Our BOMs finally match the models. DraftLine flagged a mismatched fastener spec two days before production started.Jonas Weber

Frequently asked questions
Which CAD formats does DraftLine support?
We natively read SolidWorks, Onshape, Fusion 360, and STEP/AP242 files, plus DWG drawing sets. New formats ship monthly.
Can I control who sees which revisions?
Yes. Role-based permissions govern every workspace, and released drawings can be watermarked and locked against export.
How does DraftLine handle large assemblies?
Models stream as lightweight tessellations for review, so 10,000-part assemblies open in seconds without a workstation GPU.
Do you offer an API?
A REST and webhook API ships on every paid tier, covering releases, BOM sync, and automation triggers for your PLM.
