All About SDS/2 Solutions


SDS/2 Detailing offers the highest level of automation and intelligence available in 3D steel detailing. With unparalleled connection design intelligence and high-quality drawing production, SDS/2 gives you the power to get the job done.

As the detailer inputs members, like columns and beams, connections are automatically designed with their necessary materials, bolts, holes and welds. SDS/2 Detailing takes a uniquely intelligent approach in its connection design by considering framing conditions and erectibility, automatically performing clash prevention as a part of its connection design. In addition, SDS/2 Detailing can value engineer the connections on a project, helping users to design the most economical connections to fabricate and erect. No other 3D detailing product can do this automatically.

Details and submaterial and erection drawings are automatically generated by SDS/2 Detailing, whose unmatched drawing quality saves more time on shop drawings. But drawings are no longer the only requirement of detailers. SDS/2 Detailing also provides CNC data, MRP information and 3D models, giving detailers all the tools needed to start profiting from their investment.

SDS/2 Detailing is one of the most flexible products on the market, and truly provides users with the results needed to get the job done. From detailing and fabricating entirely from the model using model approval and CNC files, to building the model and providing detail sheets generated from the model — or any workflow in between — SDS/2 Detailing handles all your detailing needs.

SDS/2 Engineering combines connection design with 3D frame analysis and member design, all neatly packaged for use as an accurate BIM model. No other engineering product can offer the model accuracy and time savings of SDS/2 Engineering.

Unlike other frame analysis products, SDS/2 Engineering creates a model that is accurate to manufacturing standards, with correct top-of-steel elevations and work point locations — enabling connections to be automatically designed while considering both fit-up and constructability. Another feature unique to SDS/2 Engineering is the ability to calculate transfer forces while designing the structure — translating to safer connections and safer structures.

Continuous changes are a staple of almost every project. SDS/2 Engineering handles these changes quickly, completely and with ease. In any change, such as layouts, member sizes, or loads, SDS/2 Engineering will reanalyze the frame, resize members, and redesign connections automatically.

As the number of engineering firms that include shop drawings as a part of their deliverables grow, SDS/2 Engineering will become increasingly valuable as an engineering tool. It shares the same 3D database with all other SDS/2 software solutions, providing a seamless bi-directional transfer of information. Engineers can use SDS/2 Engineering to analyze a model created by any SDS/2 software, or detailers can use SDS/2 Detailing to create shop drawings directly from the model created with SDS/2 Engineering. Either way, time and expense are saved and the probability of errors is significantly reduced. At any time, users can export their model to or import a model from their collaborative BIM product of choice.

Together, SDS/2 software solutions connect contractors, engineers, detailers, fabricators and erectors in a collaborative work process.

SDS/2 Fabricating is a solution designed specifically to meet the needs of fabricators. Fabricators simply request the model from the detailer, then can view the 3D model and 2D drawings, while having full control over the creation of CNC and MRP information necessary for the shop. Users may also use SDS/2 Fabricating’s reporting and status tools to track the project through completion.

Through a dashboard interface, SDS/2 Fabricating brings all the fabricators’ needs right to the users’ fingertips. From the at-a-glance progress charts to streamlined CNC tools, the dashboard is the interface for organizing and implementing fabrication.

Detailers — often required to supply CNC files to the fabricator — will also benefit from the CNC output included in SDS/2 Fabricating. CNC functionality included with SDS/2 Fabricating will enable CNC functionality on all other SDS/2 software solutions.

Both detailers and fabricators can benefit from the automation of estimating and shop data information generated by SDS/2 Fabricating.

SDS/2 Erector gives erectors powerful tools to aid in their work process. The 3D model and 2D drawings are accessible and viewable, providing the steel information in its native form. Erectors can generate center of mass and weight calculations for simple members or assemblies. Measurement tools provide the ability to verify necessary information and check erectibility clearances.

Crane placement and reach are also addressed with SDS/2 Erector. Erectors can locate their cranes around the steel model and choose exactly where the best location for placement will be. Easy to import and move around, the crane placement tool is a valuable component to any erector.

In SDS/2 Erector, erectors are afforded even more power to track and record progress to keep their job site on schedule. Through reporting and status tracking tools, daily progress can easily be recorded and future erection can be planned, allowing the model to be color coded as the structure goes up. With this measurable feedback, users can take advantage of the model to help keep the site on schedule. The actual status of the job site can be electronically sent to general contractors to allow them to adjust project schedules.

Any information in SDS/2 Erector can be transferred to any of the SDS/2 software solutions to allow easy and smooth communication through the model for the project.

SDS/2 Approval has two different applications: verify the model and check drawings before they are sent out for approval; or facilitate the approval process directly through the model.

For both checkers and engineers, SDS/2 Approval allows users to view the model and detail drawings, along with all design calculations. With various measuring tools and status fields, the accuracy of the model can be confirmed and communicated between engineers and detailers, and vice versa.

Engineers using SDS/2 Approval can run reports designed to aid in the approval process, and assign status to members to denote the level of approval, such as “approved” or “rejected.” These statuses — along with a number of other items, much like an approval checklist — can be used to color code the model to give visual feedback from start to finish of the approval process. At any point, engineers can send the approval status back to the detailer to update the detailer’s model as to which members are approved or need to be revised.

Checkers using SDS/2 Approval can take advantage of similar features, which are customized for the specific purpose of checking models or drawings. This information can be communicated back to the detailer through the same process of assigning status and generating a file that can update the in-progress model. This simple way of communicating through status updates will color code the model to alert the detailer to areas where changes are necessary.

Checking from the model is swiftly becoming a preferred method in the industry, and SDS/2 Approval provides users with the right set of tools to make it your preferred method as well. Increasing the efficiency of communicating changes will subsequently reduce error and increase profits.

With these benefits, the SDS/2 Approval is an unbeatable solution.

SidePlate Plugin

The new SidePlate for SDS/2 component and tools are plugins that offer a level of automation and intelligence for our users to efficiently place SidePlate connections into their SDS/2 projects. The plugins work by allowing a user to take a project-specific XML file, provided by SidePlate, with all the scheduled design parameters, and import that into their projects. The SidePlate component and tools work with SDS/2 v2016.11 and newer. Take a look at some of the highlighted features for both the component and tools listed below.


• The component will track which connections have been placed, to help assist in knowing that the connections used on your project are in alignment with the connections provided by SidePlate. If a misalignment is detected, a mistake can be caught early on and SidePlate can be contacted.
• The user has the ability to modify connection parameters within the component, like Plate A thickness or Dimension A. These modifications are recorded back to the XML provided by SidePlate. The XML file can then be sent back to SidePlate, during the shop drawing review process, to expedite the approval process.
• If a connection must be modified beyond standard configurations, as shown in the component edit, a Graphical mode can be selected to accommodate those modifications.


• Allows the user to locate the SidePlate moment frame column that will have connections.
• Allows the user to specify a SidePlate connection ID, when applicable, based off the automatically detected floor levels. These IDs can be specified prior to receiving the project-specific SidePlate XML file.


• Automatically detects and places the SidePlate connections at each location that has an ID previously marked. If the appropriate beams cannot be automatically detected, the user will be prompted to select the appropriate beam(s) for the connection.


Using the SidePlate for SDS/2 plugins can make the approval process faster and easier. Once SidePlate connections are imported in the model, the user may need to make some small adjustments to the connection in order to accommodate the needs of the Fabricator or Erector. These changes can be done by editing the component. By making the modifications through the component, any revised data on the connection is written back to the SidePlate XML file that was used to generate the connection. Therefore the 3D model and the SidePlate XML file are kept in sync. In addition to any revised data, the XML file is also updated to include positional X,Y,Z information on each connection. Both the revised and updated data to the XML file will be very helpful during the approval process.

When the SidePlate project or sequence is ready for approval, send the XML file along with the typical drawing submittal. SidePlate engineers will then use the updated XML to assist them in the approval process. The XML file may be returned to the detailer if the SidePlate engineer has changes.


• The following connection properties are supported for the SidePlate Moment Frame component:


• Some projects that required two different connection ID’s per beam(s)/column combination (i.e. “A1” and “A1C” for a W24x76 beam only) will now placed correctly.
• Bolt Type can now be specified and applied to all SidePlate connections globally.
