What is the difference between an advance calculator or simple online form and WebSteel system?WebSteel system is the first and unique cloud-based online integrated system of its kind in Russia and CIS, which allows a client to instantly price and design varying pre-fabricated steel buildings . A user can have a 3D rendering oа a steel building and receive its basic drawings toll-free. WebSteel system is based on parametric SOLID web modeling, which considers more than 500 000 possible variations of steel buildings, basic Construction Norms and Rules (building codes) valid in Russia and abroad and structural design loads. These features distinguish the online system from a filling-in form or a basic calculator. A steel building and its accessories cost is calculated instantly which is of a great help in instant project budgeting. On top of that, a client receives a package of online documents toll-free. The service is based on ACTIVE IMAGINATION technologies. It is also important to understand that a steel building project designing and its real-time calculations is made on the server and not in the local office as it is typically done in case of a filled-in form. A calculator is not capable to process the whole set of the steel building parameters. Normally, there too many parameters that influence the final price of a steel building. Once the insignificant changes are applied, the local calculations should be made once again, which drastically increase the processing time. Besides, neither calculator nor filling-in forms provide you with 3D nor 2D rendering features.
