CADViewer in depth

Read the full write-up

CADViewer is a browser-based CAD library for organizations embedding drawing workflows into their own software. It suits developers and operations teams that need broad file support, markup, comparison and measurement across web and mobile environments. It is a poor fit for buyers wanting an inexpensive, standalone desktop viewer.

Overview

CADViewer uses JavaScript and SVG to display and manipulate CAD drawings in a browser. Redlining, annotation, comparison of two drawings and API-based measurement make it a workflow component rather than a passive file opener. Typical applications include space management, CAFM, inventory and document management, IoT, maintenance, real-estate operations, and visualization or collaboration around CAD data.

Tailor Made Software, Ltd. has operated since 1990 and maintains offices in Seattle and Stockholm. Organizations can install CADViewer on-premises or in the cloud. That choice helps teams align deployment with existing infrastructure, but it also brings the implementation and licensing decisions associated with an embedded platform.

Key features

Formats and drawing work

CADViewer supports DWG and DXF, along with DWF, DGN, SVG, SVGZ, PDF, PNG, JPG, GIF and TIFF. The range is valuable when one browser workflow must handle engineering drawings alongside ordinary documents and images. Markup and redlining support review cycles; comparing two drawings helps identify revisions; and measurement through the API lets a surrounding application add quantitative checks instead of leaving users with display-only access.

Integration and deployment

JSON interfaces and a rich API are aimed at product teams rather than occasional viewers. The maker lists React, Angular, Vue, PHP, NodeJS,.NET,.NET Core and Servlets as supported integration environments. Named integrations include Nextcloud, Leaflet, OpenStreetMap, SharePoint, IBM Maximo and IBM Tririga, which can reduce the work of fitting CAD into document, mapping, facilities and asset-management systems.

Browser integration spans all platforms, including Android and iOS. The product is also offered for Windows, macOS and Linux environments, with self-hosted deployment for organizations that need control over where the service runs. Product pages link to an online support portal, technical documentation, a user manual and an API reference, useful resources for an implementation-led purchase.

Pricing

CADViewer is paid software with no free plan. A “CADViewer Full server – 10 Days trial” costs nothing and provides a 10-day trial license. Trial keys are obtained through the store after registering for the download and supplying installation details, so it is a short evaluation window for teams that can prepare a real integration quickly.

The “CADViewer – Full Server (Subscription)” plan costs $2,444 a year, billed at $2,444.00 / year, and includes a full server license. The “CADViewer – Full Server” plan costs $4,190 as a one-time purchase and also includes a full server license. The annual option spreads the commitment over renewals; the once-priced option is aimed at organizations that prefer a perpetual-style purchase. Perpetual licensing is described as a special exception for users with a fixed MAC/IP environment or an alternative fixed domain, under contract, so it is not a general low-cost alternative to the server plans.

These prices fit organizations budgeting for an embedded CAD capability, not individuals who only need to inspect occasional files. A download request requires an email address and supplies links to CADViewer and the maker’s CAD converters. The privacy policy describes security technology and internal safeguards while acknowledging that internet transmissions cannot be guaranteed completely secure.

Platforms

CADViewer runs across Android, iOS, Linux, macOS and Windows, and supports web, API and self-hosted deployments. Its browser model can reach users on different devices while the server or cloud installation centralizes the application. The practical benefit is a consistent CAD workflow across an organization; the trade-off is that buyers must plan hosting and integration rather than simply install a single desktop executable.

Who it's for

Choose CADViewer when your team is building CAD viewing into a business application, needs DWG and DXF alongside image and document formats, or requires markup, revision comparison and measurement in a browser workflow. Its deployment options and named framework integrations are especially relevant to facilities, maintenance, asset, mapping and collaboration systems.

Look elsewhere if the requirement is only opening files without development work, or if the budget cannot support a full-server license. The 10-day trial is useful for a prepared proof of concept but leaves little time for an unplanned evaluation.

Pros and cons

Pro: Broad support for CAD, vector, document and image formats reduces conversion requirements.

Pro: Markup, drawing comparison and API measurement support active review and coordination workflows.

Pro: Browser, cloud and on-premises options cover varied infrastructure and device policies.

Pro: JSON, a rich API and integrations with major frameworks and enterprise systems give developers several adoption paths.

Con: Full-server licensing costs $2,444 a year or $4,190, paid once, making it a substantial platform purchase.

Con: There is no free plan, and the free trial lasts only 10 days.

Con: Perpetual licensing is limited to fixed MAC/IP or alternative fixed-domain environments under contract.

Alternatives

CAD Reader is the better starting point for users wanting a freemium viewer with Android, iOS, macOS and Windows support, plus a free download.

ShareCAD suits quick browser opening without an account through its free CAD viewer, with viewer pages showing a file-size limit of up to 50 MB.

CAD Pockets is a freemium mobile and web option whose free plan includes fundamental CAD features, third-party cloud storage and 100MB of cloud space.

Glovius is worth considering when short, paid usage packs are preferable, including a 15.00 USD one-time daily pack with four hours of usage and 20GB storage.

ODA File Converter is a free choice for CAD interoperability rather than an embedded browser workflow.

3D-Tool fits Windows users seeking a free viewer for DDD, STL and 3MF files, with no CAD export in its free edition.

DWG FastView is suited to users who want a low-cost mobile and web option with premium annotations, dimensions and measurements at $3.99 a month.

DWGSee is another freemium viewer for Android, macOS, web and Windows.

Verdict

CADViewer is a strong choice for organizations embedding CAD into operational software and needing broad formats, review tools, APIs and flexible deployment. Its decisive advantages are integration depth and workflow features; its decisive drawbacks are the high full-server cost, absence of a free plan and brief trial. Buyers seeking a simple, inexpensive viewer should choose an alternative.

Verdict

CADViewer combines browser-based CAD viewing with markup, comparison, and measurement features, plus a broad list of formats and integration environments. Its trial lasts 10 days; full server pricing is listed as $2,444 a year or $4,190, paid once.
