Log in with your CIVIL4CAD account and download CIVIL4CAD_setup.exe on the Download page — the step-by-step installation guide is there too. Later upgrades are offered directly inside ZWCAD.
ZWCAD 2025 and 2026, 64-bit. If you don't have ZWCAD yet, ask us for a combined CIVIL4CAD + ZWCAD offer.
You can try CIVIL4CAD free for 30 days with no obligation. Click “Try it free”, log in (or create an account), download and install CIVIL4CAD, then request the trial licence in ZWCAD (License Manager → ONline activation).
Specialised modules licensed on top of core CIVIL4CAD: PIPE for gravity sewer and storm water networks (Pipe Networks), RAIL for 25 kV overhead contact lines. Without the add-on licence their branches in the tree are not available.
Your CIVIL4CAD account — the same e-mail and password work on civil4cad.com and in CIVIL4CAD. You can create one for free on the Create an account page.
Yes. The CIVIL4CAD interface is available in Croatian and English — choose the language in the options (C4C_OPTIONS).
The CIVIL4CAD (or short C4C) command opens the palette with the tree: point groups, object groups, surfaces, alignments and GIS themes. If the ribbon is missing, run C4C_MENULOAD.
Create a point group (from points/blocks in the drawing with a layer filter, or from CSV), then create a surface from that group in the tree. Add terrain lines as an object group, set them as breaklines and rebuild the surface.
Build TIN surfaces for the existing and design (or earlier) states and run the surface difference — the result is a difference surface with cut and fill volumes. For section-based quantity reports use the XLSX report tool.
In the drawing itself (DWG). When you send the drawing to a colleague who has CIVIL4CAD, they see the same point groups, surfaces and settings.
In the options (C4C_OPTIONS) choose the drawing's coordinate system from the EPSG catalogue. It is stored in the DWG, and base maps, themes and points from other systems are reprojected automatically.
CSV and TXT plus the survey formats KOO, F25, POL, 25T and LST, using format templates. Points can also be collected directly from drawing objects.
Yes — through the GIS part (MAP4CAD) you add themes from shapefiles, WFS services, GML and CSV, with attribute tables, labels and thematic styling.
Add a WMS/WMTS base map (for example your national geoportal) — it is displayed in the drawing's coordinate system. Google Maps and Street View at the picked location are also available.
