EzySurf is an older but enduring utility often found in CAD resource forums and community libraries:
– Type one of the Ezysurf commands, such as EZ or TIN , to verify that the add‑on is working correctly.
: AutoCAD LT does not support AutoLISP. Solution : Upgrade to a full version of AutoCAD, or consider using BricsCAD (which runs LISP and is more affordable). Ezysurf Download
: One of EzySurf's most powerful features is its ability to compute the exact volume of earth that needs to be moved (cut) or added (filled) between two surfaces. Cross Sections
: Select XYZ-in from the EzySurf dropdown panel, select your data text file via the utility browser, and run the execution script.

The core strength of Ezysurf lies in its ability to automate the generation of Digital Terrain Models
Click to automatically plot thousands of physical nodes inside your model space canvas. Step 3: Triangulation (TIN) and Contouring Select Create TIN/TRN from the EZYSurf tool strip.
For older AutoCAD versions (pre‑2010), the menu might also be loaded by typing MENU and directly selecting the .MNS or .CUI file.

Its core features include:
As shown in the table, Ezysurf occupies a unique niche: it offers core terrain‑modelling functions at a fraction of the cost of Civil 3D, while remaining within the familiar AutoCAD environment. For small to medium‑sized projects, it provides excellent value. Users in forums report that “the contours appear to be pretty accurate” and that the software “is well worth the money”.
Q: Can I use Ezysurf on multiple devices? A: Yes, Ezysurf is available on multiple platforms, including Windows, macOS, and Android.
The software automatically creates Triangulated Irregular Networks (TIN) from imported point data. TINs are the foundation of digital terrain models, representing the surface as a mesh of non‑overlapping triangles. Ezysurf also supports the creation of TRN (Triangular Networks), which are similar but may use different triangulation algorithms.
Based on user documentation and industry use cases, the following performance factors stand out:
