TraceBIM turns the way architects already design — sketching and redlining — into a live parametric BIM model, then produces professional, stamp-ready drawing sets. No Revit. No BIM modeler. No repetitive drafting.

The product
You design by giving redlines. TraceBIM does what a skilled BIM modeler would — builds the model, keeps it consistent, and drafts the documents — so you stay focused on the decisions only an architect can make.
Sketch over a plan or upload a marked-up drawing. TraceBIM reads clouds, arrows and notes the way a job captain would — then makes the change.
A reactive dependency graph keeps walls, openings, dimensions and annotations consistent. Move a wall and every dependent element updates in one transaction.
Floor plans, elevations, sections, dimension strings, grids, tags and title blocks — organized on standard sheet sizes, ready for your review and stamp.
Correct line weights, architectural dimensioning in feet-and-inches, standard scales and notation conventions are applied automatically to every drawing.
Export any sheet to a crisp vector PDF at true scale — ARCH D, ARCH E1 and more — with your title block data filled in.
A full drafting workspace in the browser with touch support — redline on the couch with an Apple Pencil, refine at your desk. Your projects sync everywhere.
How it works
Three steps between your intent and a stamped-ready sheet set.
Start from a sketch, an existing floor plan photo, or a blank sheet. Mark it up exactly like you'd redline a junior's drawing — clouds, arrows, notes.
upload · sketch · annotateYour markups become parametric walls, doors, windows and rooms in a live BIM model. Review every interpretation and correct it in one click — TraceBIM learns your conventions.

Every output is held to professional architectural drawing standards — because a contractor will build from it.

Prices shown are planned launch pricing and may be adjusted before billing goes live. Early-access members will always be notified before any charge. Note that every exported sheet, on every plan, carries a “DRAFT — NOT FOR CONSTRUCTION” notice: TraceBIM is a drafting tool, and drawings still require review and stamping by a licensed design professional before they go to a contractor. Paid plans remove the TraceBIM branding line, not that notice.
About
Most architects don't model — they design. The craft happens in sketches, trace paper and redlines, and then weeks disappear translating that intent into BIM software built for specialists. Small practices either learn Revit, hire a modeler, or draft everything by hand.
TraceBIM removes that translation step. It treats the redline itself as the design instruction — the same way a principal hands markups to a job captain — and automates the repetitive modeling and drafting that follows, while every output is held to the standards of a professional drawing set.
The result: licensed architects who have never opened a BIM tool can carry a project from first sketch to stamp-ready construction documents, entirely in the browser.
Founder
Associate Architecture · BIM specialist · Software engineer
TraceBIM was conceived, designed and built end-to-end by Farhad Shariatzadeh — one of the rare practitioners who has worked professionally on both sides of the problem it solves. He holds a Master of Architecture and spent five years as a BIM modeler producing construction document sets, living daily with the gap between an architect's redlines and the finished model — and with the exacting standards a professional drawing set has to meet.
He also holds a Master of Science in Computer Science and spent six years as a backend software engineer building production systems at Oracle and Doosan GridTech — enterprise platforms and power-grid software where correctness and reliability are non-negotiable. TraceBIM is the synthesis of those two careers: every feature is specified by someone who has produced drawing sets for a living, and engineered by someone who has shipped software that enterprises and utilities depend on.
The entire platform — the parametric geometry engine, the reactive dependency graph, the drawing renderer and the cloud infrastructure — is his sole-author work, built by constantly swapping between the architect's hat and the engineer's. That dual fluency is TraceBIM's foundation, and its promise: software that understands drawings the way an architect does, built to the standard an engineer demands.
