![]() ![]() Then we can start to play around the distance value and see how our structural system responds. Here we setup the distance of the vertical braces of the truss system as a parameter and then we plug it into the FEA solver. If you visit Karamba3D website, you will find several models, like the one below. If I want to summarise in one sentence why even we want to use parametric tools for structural designs, then I would say because of the so many possible options of an optimal layout which we cannot replicate by manual geometry inputs, or it would be too time consuming. Parametric modelsīefore I go to some details of my telecom tower model, I want to show you some other examples where parametric designs are so useful in the field of structural engineering. But today I'd like to show you how I used the Grasshopper, Karamba3D and other plugins in Rhino for a telecom lattice tower. ![]() Nowadays more and more software companies introduce parametric tools into their products, like Dynamo for Revit. So we decide a certain input should be i.e in the range from 1.0m to 3.5m with a steps of 0.1m. The parameter can have a range and steps. We say parametric models when a design input of the model is a parameter rather than a scalar input. But here is, where parametric or computational design comes in. It worthless to say that the optimality of the design will be based on the seniority of the engineer and years of experience. This makes it very cumbersome to come up with a very optimal design and the whole process is laying on the engineer's judgement. If we want to experiment with new geometries, topologies or layouts we have to basically rebuild the whole finite element model (FEM). The geometry of the structure under analysis is a static (hard coded) input. While these programs are very intuitive and usually provide great user experience, the concept are more or less the same. StaadPro, SAP2000, Dlubal, Autodesk Robot, AxisVM, among others. FEA SoftwaresĪn evolution of the command line tools were FEA software packages where we have usually a nice user interface, several algorithms, post-processing opportunities and even code check modules. But on the other hand they are lacking to provide a great UI/UX and the geometry is a static input. These kind of tool they still exist today and they are very useful, specially when we want to integrate them. SomeFeaCommand input_file output_file -some_paramaters -some_options
