FDN - Find Double Nodes
FDN - Find Double Nodes add-in for Autodesk® Revit® enables structural designers to find nodes that are close to each other but not connected in the analytical model of a building. FDN finds unconnected nodes within the given margin and users may isolate then zoom into the selected nodal area and ultimately fix the problem.
With the version 2.0 FDN got mature and now providing new functionalities along with a brand new user interface and a faster multi-threaded finder. User may check the analytical model with the fundamental functionality “Find”. The list of nodes are visually presented to your via an interactive data grid. Through this grid, selection of a row simultaneously selects and indicates the node visually inside the Revit window.
Modeless window of FDN allows you to interact with the model while it is open thus providing you a smooth workflow. You can continue working with Revit while you are using FDN alongside. Once you select the node you can easily isolate it along with the other connected elements. You may zoom into the problematic area and with the isolated view and now you can operate in precision.
After installing FDN, users need to activate the software. A “Trial License” can be obtained for free that will enable full functionality of the application within a specified time frame. Please initiate your trial at the License Tab.
Users are strongly encouraged to try out FDN with a free trial license. After the trial period ended, a “Standard License” can be purchased that will provide 365 days to run the application again with full functionality. In-app purchasing and automatic activation provides a hassle free system for licensing.

It is vital to set up the Analytical Model properly in order to carry out the FE analysis correctly. With the help of FDN, analysis process is no more prone to inaccurate analytical modeling due to analytical nodes not connected to each other. BIM-WITHSTAND humbly present you this useful tool to support your structural design life cycle.
Analytical elements that have nodes that are too close in geometry but in fact not connected will cause problems in many steps of structural analysis. Such as the occurrence of finite elements which are very small, auto meshing process not converging resulting in incoherent mesh, incorrect stiffness matrix, wrong results and many more...
Finding the unconnected nodes manually becomes a huge deal for a structural designer. Analysis software (Autodesk® Robot™ Structural Analysis, Sap2000, Etabs, Staad Pro, etc.) may provide tools to remedy this but consume considerable time and effort. It is better to find the problem with the main Revit model before sending it to analysis.
FDN will remove the trouble of manually checking the connectivity of each node, and save your time. By listing the unconnected nodes, you can now correct those nodes before sending your model to analysis. Especially in larger models where it is hard to see the connectivity, FDN will save your time and show those nodes flawlessly.
To check the connectivity easily, user can select the node from the list and zoom into the area by clicking zoom and see (the structural elements that are relevant) with an isolated view. By isolating it gets easier to analytically adjust and correct the error. Furthermore, the modeless GUI window provides a smooth workflow. You can interact with Revit while you are using FDN. This is a huge plus as you do not need to close and reopen the application and work along with your model. When you pin point the error it is also easy to fix it by the tool provided with FDN.
