CMS IntelliCAD also offers a full suite of 2D and 3D AutoCAD compatible drawing tools. CMS IntelliCAD STD is the most powerful CAD software within price range.

CMS IntelliCAD is the intelligent and affordable full-featured CAD Software choice for engineers, architects and consultants, or anyone who communicates using CAD drawings. It is designed to give you unrivaled compatibility with Autodesk AutoCAD, and is fully programmable with hundreds of third party solutions. CMS IntelliCAD also offers a full suite of 2D and 3D AutoCAD compatible drawing tools.

1. Unrivaled Autodesk AutoCAD Compatibility
CMS IntelliCAD provides a high degree of compatibility with the AutoCAD command set, as well as AutoLISP and ADS. That means you can get to work immediately using the AutoCAD files, commands and applications you rely on.

2. AutoCAD & Native DWG Support
Like AutoCAD and AutoCAD LT, IntelliCAD uses DWG as its native file format. IntelliCAD opens, edits, and saves any existing DWG files saved in version 2.5 through 2009, without conversion or data loss. That makes CMS IntelliCAD more compatible with older versions of AutoCAD than AutoCAD itself!

3. 3-D Surface Commands
IntelliCAD's sophisticated 3-D capability allows creation of high-quality 3-D models. You can display them as wireframes, with hidden lines removed, or with surface shading.

4. ACIS 3D solid modeling (PRO edition)
CMS IntelliCAD's full version is able create, edit, import and export ACIS .sat 3D solid files. PRO users can download and install and use CMS IntelliCAD Traceparts 1.0 for FREE. From CMS IntelliCAD it's possible to access more than 1 million part drawings in DWG, DXF and solid 3D ACIS file format.

5. Autodesk Development System (ADS) support
To run your custom Autodesk Development System (ADS) applications in IntelliCAD, simply recompile them using the libraries included on the IntelliCAD CD-ROM. That's all it takes. Prominent third-party developers are recompiling their popular ADS and C++ applications to run with IntelliCAD, too.

6. AutoLISP support (including .DCL)
IntelliCAD preserves your investment in existing custom applications by supporting the LISP programming language. You can run AutoLISP applications that reference any of the hundreds of AutoCAD commands with little or no modification. What's more, IntelliCAD reads DCL files that contain dialog control language statements.

7. Support for AutoCAD command line
IntelliCAD supports hundreds of AutoCAD commands. Select AutoCAD commands from the pull-down menus and toolbar icons, or type AutoCAD command syntax at the optional command line prompt - whichever best fits your work style.

8. Digitizer Support
Many drafting departments have established routines using digitizers within their CAD workgroup. For CAD departments that utilize digitizers as input devices, IntelliCAD is now a viable option, providing advanced Windows features and AutoCAD-compatibility at an affordable price. IntelliCAD supports both tablet mode for tracing and the use of tablet menus for command input.

9. IntelliCAD: AutoCAD Menu (MNU) & Script (SCR) Files
IntelliCAD supports AutoCAD menus (MNU), dialog boxes (DCL), fonts (SHX), scripts (SCR), and symbol libraries, so you can easily transfer custom AutoCAD environments into IntelliCAD and continue working in your favorite drafting environment.

10. Raster Image Display
IntelliCAD lets you view and export WMF, EMF (Enhanced Metafile), and SLD (slide) files. It also displays any BMP, GIF, JPG, TIF, PCX, and CALS Type 1 images that are embedded in DWG files using the raster technology licensed from Adeko.
