Overview
CSI SAP2000
SAP2000 provides you with a versatile environment for the modeling, analysis, and design of any type of structural system. Whether you are working on simple 2D frames or complex 3D geometries, you can create models using powerful templates and a graphical user interface that simplifies the engineering process. It handles everything from basic static analysis to advanced dynamic non-linear applications, making it a standard tool for professionals in the transportation, industrial, and public works sectors.
You can perform integrated design for steel, concrete, and aluminum structures within a single interface. The software automates complex calculations for wind, wave, and seismic loads, ensuring your projects meet international building codes. It is designed for structural engineers who need a reliable, all-in-one solution that scales from small residential tasks to massive infrastructure projects like bridges and stadiums.
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.
