CivilGEO

CivilGEO provides specialized engineering software designed to simplify complex hydraulic and hydrologic modeling. You can perform detailed river analysis, floodplain mapping, and storm water management using tools that integrate directly with AutoCAD, MicroStation, and ArcGIS environments. The platform automates many of the manual tasks traditionally associated with HEC-RAS and HEC-HMS, allowing you to focus on engineering decisions rather than data entry.

You can build 1D and 2D models quickly by leveraging built-in automation for cross-section extraction and terrain processing. The software is primarily used by civil engineers, hydrologists, and government agencies to handle flood studies and infrastructure design. By streamlining the modeling workflow, you can significantly reduce the time required to complete regulatory submittals and technical reports.

PTC Onshape

Onshape is a professional-grade CAD platform built entirely in the cloud, eliminating the need for expensive hardware or complex installations. You can design complex 3D models, manage your product data, and collaborate with your team in real-time from any web browser or mobile device. Because it uses a single source of truth, you never have to worry about version control issues or overwritten files again.

You can streamline your entire product development lifecycle by using built-in release management and automated workflows. The platform is designed for engineering teams of all sizes, from startups to global enterprises, who need to move faster and work more flexibly. It solves the traditional headaches of file-based CAD by providing a secure, always-accessible environment where your entire team can contribute simultaneously.
