Construction drawings

Construction drawings software with pins and 3D/BIM overlay

Upload plans as PDF or image and drop pins with punch items, tasks, RFIs and notes directly on them. Calibrate any drawing to the 3D/IFC model, color elements by progress and bill quantities straight from the model — all in one place.

Why managing drawings in folders fails

Plans live in email threads, shared folders and printed copies on site. Nobody knows which revision is current, and defects marked on paper never reach the office.

Scattered revisions

Floor plan v3, v3_final, v3_final_FIXED — across email, cloud storage and the site container. The wrong revision gets built.

Defects lost on paper

Punch items circled on a printed plan never make it into a tracked list. Nobody is assigned and nothing gets closed.

No link to the model

The 2D drawing and the 3D/IFC model live in separate tools. Quantities are re-measured by hand for every act.

Office and site disconnected

The site marks up a plan, the office never sees it. Coordination happens over the phone and gets forgotten.

Everything your drawings need in one module

From a flat PDF to a live, pinned, model-aware plan.

Upload plans in seconds

PDF or image (JPG, PNG, WebP) up to 50 MB. Multi-page PDFs auto-expand into separate drawing sheets — up to 30 pages.

Pins on the drawing

Click anywhere on the plan to drop a pin — a new or existing punch item, a task, an RFI or a note. Each pin opens the full record.

Disciplines and versions

Tag drawings by discipline — architecture, structural, electrical, plumbing, HVAC, fire safety. Upload a new version and history with all pins is preserved.

3D / IFC overlay

Calibrate a drawing to the 3D model with two points and overlay the plan on the BIM geometry. Inspect element type, storey, material and dimensions.

Bill straight from the model

Select elements in the overlay and propose an act — quantities come from the model, prices from the contract position. Color elements by progress.

Open pins and sharing

Filter pins by type and status, see open issues at a glance, and keep office and site on the exact same current plan.

How it works

From upload to a pinned, model-linked drawing in four steps.

1

Upload the plan

Pick the project, give the drawing a title and number, choose a discipline and upload the PDF or image. Multi-page PDFs split into sheets automatically.

2

Drop pins

Click on the drawing to place pins — punch items, tasks, RFIs or notes — exactly where the issue is. Each pin links to the live record.

3

Calibrate to the model

Set two matching points between the drawing and the 3D/IFC model. The plan overlays the BIM geometry, aligned and to scale.

4

Track and bill

Filter open pins, color elements by progress and propose acts with quantities pulled straight from the model.

Who it's for

Anyone who works off drawings on a real construction site.

Site managers

Mark every defect and instruction on the exact spot of the plan, assign it and track it to closure.

Technical supervisors

Keep one current revision per discipline and link RFIs and submittals to the drawing they affect.

BIM coordinators

Overlay 2D plans on the IFC model, inspect elements and catch mismatches before they reach the field.

Quantity surveyors

Bill executed work with quantities taken from the model instead of re-measuring by hand.

Drawings software vs PDF folders — what's the difference?

Why a dedicated drawings module beats a shared folder of PDFs:

Frequently asked questions

What file formats can I upload?+

PDF and images (JPG, PNG, WebP) up to 50 MB. A multi-page PDF is automatically expanded into separate drawing sheets — up to 30 pages.

What can a pin be?+

A pin can be a new or existing punch item, a task, an RFI or a plain note. It is placed exactly where you click on the drawing and opens the full record.

How does the 3D / IFC overlay work?+

You set two matching points between the drawing and a 3D model in top view. The plan is then overlaid on the BIM geometry, aligned and to scale, so you can inspect elements and pin them.

Can I bill work from the drawing?+

Yes. In the 3D overlay you select model elements and propose an act — quantities come from the model and prices from the matching contract position.

What happens when I upload a new version?+

The previous version is preserved in the version chain together with its pins. You always see which revision is current and who uploaded it.

Can subcontractors see the drawings?+

Drawings are part of the project, so everyone with access to the project works off the same current plan — office and site alike.

Do I need a BIM model to use drawings?+

No. Pins, versions and disciplines work on any PDF or image. The 3D/IFC overlay is an optional extra when the project has a completed IFC model.
