AViCAD is a professional CAD solution designed for users who want an AutoCAD®-compatible workflow without being locked into a single licensing model. It opens, edits, and saves native DWG files while preserving familiar commands, customization options, and drafting conventions — so you can keep working the way you already do.
Rather than focusing on hype or drastic change, AViCAD is built for continuity: it’s compatible with existing files, uses recognizable tools, and offers licensing options that let you choose how you own and maintain your CAD software over time.
Many CAD users look for alternatives not because they want to switch and relearn how to draw, but because they want more control over tools, workflows, and long-term usage.
AViCAD is chosen by professionals who want to maintain DWG compatibility, avoid unnecessary complexity, and work with software that supports all kinds of projects without forcing constant upgrades or add-ons.
With a CAD alternative like AViCAD, you will always get a lower price without sacrificing quality.
AViCAD uses DWG as its native file format, allowing you to open, edit, and share drawings without conversion or cleanup. This makes collaboration with clients, consultants, and teams using AutoCAD® or other DWG-based software straightforward and reliable.
Your drawings always remain intact — including xrefs, layers, blocks, styles, and annotations.

AViCAD supports the command structure CAD professionals expect, along with customization through the CUI editor, scripts, and AutoLISP routines. Toolbars, shortcuts, and tool palettes can be adjusted to match your existing workflow, minimizing retraining and overall disruption.
Whether you’re working on legacy drawings or active project files, AViCAD lets you continue without reformatting or restructuring your drawing’s data. You can move between AViCAD and AutoCAD® environments confidently, knowing files will remain compatible, making AViCAD an excellent AutoCAD alternative.
In addition to DWG and DXF, AViCAD supports a wide range of import and export formats. This allows teams to integrate files from multiple sources and deliver drawings in formats clients and partners expect — without relying on extra utilities.
AViCAD includes the core drafting tools needed for technical drawings, schematics, and layouts. Layers, blocks, annotations, and dimensioning tools are designed for accuracy, repeatability, and efficient production.

Built-in 3D tools let you model, view, and work in 3D alongside traditional 2D drawings. This supports a wide range of use cases — from mechanical layouts to architectural and structural work — without requiring separate software.
Choose Perpetual Ownership or Subscription Access
AViCAD offers both perpetual and subscription licensing, allowing you to choose the model that best fits your business or project needs.
A perpetual license means you purchase the software once and can continue using that version without expiration and without an ongoing subscription. You may use the software for as long as your Windows operating system supports it.
As Windows evolves over time, you can optionally upgrade your AViCAD license to a newer version for a nominal upgrade fee — you are not required to repurchase the software.
A subscription license, on the other hand, provides short-term or flexible access for users who prefer a lower upfront cost or need CAD software for a defined period. When a subscription ends, access to the software also ends, with no long-term obligation or renewal requirement.
AViCAD supports both approaches, so you can choose ownership or flexibility depending on how you work.
Because AViCAD offers both licensing models, you are not forced into a single long-term commitment.
This flexibility makes long-term planning easier for small teams, consultants, and firms that manage a mix of ongoing and short-duration projects.
AViCAD includes the Mech-Q engineering tools, providing access to mechanical, piping, structural, and ducting functionality inside the same CAD environment. These tools are included at no additional cost, reducing the need for separate engineering add-ons.
Architectural tools for elements such as doors, windows, and roofs help speed up design and documentation. A 10,000+ block library and manager is also included. These utilities support both 2D and 3D workflows and integrate directly into standard CAD drawings.
Because the interface, commands, and workflows are familiar, experienced AutoCAD® users can transition quickly. AViCAD is designed to make you feel right at home from day one, helping users stay productive without extended retraining.
AViCAD is supported by training videos and direct support from knowledgeable CAD professionals. This makes it easier to get answers, resolve issues, and continue working without long delays.
AViCAD works well for professionals and teams who:
If your work involves BIM or cloud-based platforms, AViCAD can still play an important role in your workflow. AViCAD is designed as a straightforward, DWG-based CAD environment that can import BIM and 3D model data and be used alongside other design tools to complete drawings, coordination, and documentation with consultants.
Rather than locking you into a single ecosystem, AViCAD focuses on compatibility, control, and efficient drafting — making it a practical tool for producing and managing drawings across mixed software environments.

Choosing the right CAD software involves more than upfront cost. You want to be sure it works with existing drawings and day-to-day workflows, offers flexible licensing, and includes the tools you’ll need over the long term. AViCAD is designed to balance these key factors, providing a stable platform that supports your ongoing work for years to come.
Some professionals are reconsidering how CAD software is licensed and packaged today.
