eTakeoff

eTakeoff Dimension is Windows desktop software for PDF and electronic quantity takeoff in construction estimating. It suits estimators and shared estimating teams that build quantities from drawings, especially when they already use a supported estimating system. The main trade-off is a focused takeoff workflow against annual per-user costs and no Mac version.

Overview

Dimension records measurements in a database while takeoff proceeds, allowing a company’s measurement history to grow with continued use. Network or cloud-hosted multi-user access supports concurrent work on projects and drawings, while record locking helps prevent conflicting edits. That combination is practical for estimating departments dividing work across a shared set of documents, although subscription costs increase with every paid user.

The product is part of a broader install family that includes eTakeoff Bridge, eTakeoff Navisworks Integrator and eTakeoff Server. Support includes a support center, training guide, training videos and support sessions, giving teams several routes to onboarding and help.

Key features

Drawing measurement and estimating

Digital measurement tools handle the central PDF takeoff task, while assembly capabilities help turn measured components into repeatable estimating structures. Microsoft Excel integration connects quantities with a familiar spreadsheet workflow. Dimension also names Sage Estimating, Trimble WinEst and Gordian 4Clicks as estimating integrations, so it is particularly compelling for firms already committed to one of those systems rather than buyers seeking a general construction-management suite.

Shared data and security

Measurements are stored as work is performed, creating a persistent database instead of leaving quantities only in individual drawing sessions. Multi-user access can run over a network or be hosted in the cloud; record locking is an important safeguard when several estimators edit the same project or drawing. Database security is listed as a Dimension feature, which matters for organizations managing shared estimating data.

Trade and AI tools

For communications and security estimating, Pattern Search locates matching drawing symbols and converts selected results into count measurements. The company describes SnapAI and Togal.AI as its two AI takeoff technologies, while Togal.ai is also sold as a separate paid add-on. These options may help teams with symbol-heavy or AI-assisted workflows, but the add-on materially changes the subscription cost.

Pricing

A 15-day trial provides a short evaluation window before committing. The free viewer can reduce the number of full subscriptions needed for read-only participants, but active estimators require a paid plan. Renewal is annual, and every additional paid seat adds another per-user annual charge.

Platforms

Dimension is desktop software for Windows and is explicitly unavailable on Mac OS. That makes it workable for Windows-based estimating offices but a poor fit for Mac-only teams. Its related products include server, bridge and Navisworks integration components, while the core platform remains desktop Windows software.

Who it's for

Choose Dimension if your work is centered on PDF drawing measurement, assemblies and electronic quantity takeoff, particularly with Sage Estimating, Trimble WinEst or Gordian 4Clicks. Shared projects, record locking and a growing measurement database suit departments rather than isolated one-off estimators. Look elsewhere if you need native Mac support, a primarily mobile or browser-based workflow, or a lower-cost model for many occasional users.

Pros and cons

• Pros: Digital measurement, assemblies and Excel integration cover the core estimating workflow.
• Pros: Network or cloud sharing with record locking supports concurrent team takeoff.
• Pros: Database storage preserves an expanding body of measurements, while Pattern Search supports communications and security counts.
• Pros: Named integrations with Sage Estimating, Trimble WinEst and Gordian 4Clicks help established users connect takeoff to estimating.
• Cons: Advanced and Premier use substantial annual per-user pricing, and Togal.ai costs an additional $1,800 per user per year.
• Cons: Windows-only operation excludes Mac users.
• Cons: The free Basic viewer is for viewing, so full takeoff work still requires paid seats.

Bidwright offers free desktop apps on macOS, Windows and Linux, including a single-user edition, so it suits teams that need cross-platform access.

Buildxact is a web and mobile freemium option with complimentary credits, AI estimating and professional proposals for buyers wanting a broader online workflow.

STACK provides browser and mobile access plus a free tier limited to one active project, 300 plan pages, 50 measurements per project and one viewer seat.

Trimble Quadri is worth considering when model viewing, commenting and distance or area measurement are more important than dedicated PDF takeoff.

Trimble Viewpoint Vista is an alternative for organizations seeking a cloud-hosted or on-premises ERP deployment.

ConEst IntelliBid is another paid estimating product with pricing that depends on edition and user count.

HCSS is a paid option sold by custom quote according to company type and role.

Verdict

eTakeoff Dimension is a strong match for Windows-based construction estimating teams that need drawing measurement, assemblies, shared projects and connections to established estimating systems. Choose it for that focused, database-backed workflow and team coordination. Look elsewhere if annual per-user pricing, the expensive Togal.ai add-on or the lack of Mac support conflicts with your budget or platform requirements.
