<p>I am generating ifc plates and try to add openings to them using Geoemtry gym and Grasshopper. However ggIFCO always returns an Invalid Cast Error for me. Suprisingly using the old ggIFCO component seems to work but the geometry is not displayed in the correct location. Did anyone find a similar error? Any suggestions how to solve this?</p>

<p>Hi Jon,</p>
<p>In a previous version of the <u>ggrobottokaramba</u> plugin you had provided a component that bakes the output of a Karamba model directly into Robot.<br/> In the most recent versions of the ggrobot and ggkaramba plugins, this component is not available. <br/> <u>How can this be done now?</u> <br/> <br/> I tried reconstructing the beam grid of my Shell into ggbeam components but that does not transfer well into Robot and gives me an error<br/> 1. Solution exception:Request for generated beam has coincident node points and is ignored at node 24 12.3269357755017,85.1332956591713,7.25152918466679</p>
<p> </p>
<p>Additionally, I tried using ggKarambaIFC but once I put in the model output from Karamba assemble I get this error!!<br/> 1. Solution exception:Method not found: 'System.String Karamba.Materials.FemMaterial.get_name()'.<br/> <br/> Finally, I am unsure as to how I can use the ggbake component. What does it connect to? <br/> <br/> Thank you!<br/> Habiba</p> Grasshopper for Mac now Supportedtag:www.grasshopper3d.com,2016-03-31:2985220:Topic:14974622016-03-31T12:00:46.042ZJon Mirtschinhttps://www.grasshopper3d.com/profile/JonMirtschin

<p>Is there a way to create an IFC Wall using a Brep as a representation and series of Breps to represent voids? I imagine it would be a similar thing to editing profiles in Revit, but in Grasshopper.</p>

<p>I do appreciate that there is a learning curve to generating IFC in Grasshopper, but once you get a grasp of it, the opportunities for generating BIM objects, attributes and relationships in Grasshopper has few limits.</p>

<p></p>
<p>Tie elements are available in GSA to emulate cables and tensile rods. They can be generated in the Geometry Gym plugin be assigning the Beam type in the Beam Attributes component. Model attached.</p>
<p></p>

<p></p>
<p>Note this will force the GSA solver to use a non linear solver to enforce this. If you're confident your loading scenarios will only induce tensile forces, you can still use the static solver by setting a bar element (and then verifying manually no compression force exists).</p> SAP2000tag:www.grasshopper3d.com,2012-05-16:2985220:Topic:5970062012-05-16T19:49:44.760ZJon Mirtschinhttps://www.grasshopper3d.com/profile/JonMirtschin

<p></p>
<p>SAP2000 uses slightly different terms to other structural analysis software (ie Load Patterns are equivalent to Load Cases in most other software). I am trying to do my best to ensure the GH plugin terminology matches, but still needs improving and this doesn't help with what connects to what. If you spot something you think can be improved, please let me know.</p>
<p></p>
<p>I've attached my subtle changes to your GH def. Note that at least one of the forces needs to be activated to true to get results to emit.</p>
<p></p>
<p>I had a request to report stress the other day, but when I went to check you can only extract the force using the API, so I need to find some time to do some additional coding to calculate these from the section properties. Axial force you might be able to quickly calculate from the force using GH components. </p>
<p></p>
<p>Note also I recently enabled the ability to nominate the SAP model units (ie Feet and kips) from a right click on the ssiBake button. This should be done prior to the first exchange to SAP, so either save, close and restart Rhino, or disable the solver prior to first opening the model to make the change.</p>
