Try updating the IFC plugin fromhttp://www.geometrygym.com/downloads as I fixed a cause of this problem yesterday.  A work around is to save, close and reopen the grasshopper model.

If you want to start a discussion thread within this group it might be better where we can add attachments etc.

Hi Jon,

I have intalled and licensed your IFC plugin.But when I open your examples,all the icons are still red.They show similar message like this:I'm using rhinoSR9 and grasshopper 8.0066.Could you tell me what does this mean?

many thanks!

Hi Jon,

I read your reply to someone's problem similar to mine.It seems to be solved...

Thank you for going to the trouble.

I have that same problem as @first1 any idea how to solve this? ( i have newest grasshopper 8.0066 , IFC plugin etc )

Run Rhino command GrasshopperDeveloperSettings and untick COFF loading.  Restart Rhino.  Let me know if this doesn't resolve the problem.

Now works thanks !

Hi i have question about any tutorials or help with making columns or generic model ( fancy forms from Rhino ) to simply importing them to Revit ? Slabs are in you definitions and this work perfectly now. Thanks for any help !

More examples are coming, I'm setting up some new components to permit a more "family" based approach that will more consistent with Revit.  If you want to post/email any models in the mean time I'm happy to help.

What is the error message?  Try running rhino command grasshopperdevelopersettings and unticking COFF loading.  Restart Rhino and see if it fixes the errors.

Hey Jon, 

My other problem has been solved. Now I have another question, I want to know how I can change the ssiLP from Dead load to snow or live load? I cannot modify this comportment !

Also how I can check the Buckling(P)? 

Thanks a lot..

Hi,  Glad to hear you solved your problem.  Have you found to filter the blog for posts specific to SAP using the tag cloud?  http://geometrygym.blogspot.com/search/label/SAP2000

If you right click on the Type input for the load pattern, you'll see a context menu as per this image.  You can run non-linear analysis from GH, I'll look into a buckling option but you'll need to do it manually having baked the model to SAP.  Member design is another I meant to have enabled by now.  Cheers,  Jon

Thanks a lot Jon for a quick answer. Could you please tell me why the ssiS component is red? And How I can find the axial stress in the elements?

When I bake the structure, The SAP doesn't show anything! Do you know why?

very great plugins ~~ I`m your fans  jon~~

Hey Jon,

I've a question about the GSA link settings in Grasshopper. How can I define the link settings in the SSI plug-in? I want to set the link on only tension but can't find a way to do this. 

Thanks in advance,

test model

method 1

method 2

Hi Jon

I want to put this several pieces of rhino surface into revit, I try to use the above two kinds of methods, but it didn't worked , Have you what a good method to deal with this problem?Thanks for any help !

Here is the test model file .https://www.dropbox.com/s/feyjduqi60dfl2i/test%20model%2020120627.3dm

looks like I'm 1000th member

Congratulations on being the 1000th member, it's a milestone I'm very thrilled to achieve and hope reflects on the benefits users are getting from my developments for Grasshopper.

Hi Jon, I am wondering what value I need to put into the RHS component to create the fillet? I have tried 0.1 to 1 and up to 90 with an expression to turn it into radians. Everytime the corners have remained at right angles. What vaule would you recomend? Or have I got something wrong?

Thanks 
Matt

Hi Matt,

I've put my response to your question into this discussion thread:

http://www.grasshopper3d.com/group/geometrygym/forum/topics/structd...

How to apply a lineload ?
I suppose one should use ggCUDL.

But when i export to Robot the load vector is zero.

What to do?

Hi everybody,

I try to use the ggRobotSolver to get the results directly within Grasshopper. The ggQueryNodeDisp gives a runtime error (see image).

Did someone already use this feature ?

Jon, could you explain how to proceed or send an example ?

Thanks!

Hi,

I found the problem : i did'nt feed the N input of  ggQueryNodeDisp with correct data : N must be a ggNode output. But I get no results from ggS !

Can you test if this example is working?

http://geometrygym.blogspot.com/2011/03/galapagas-and-gsa-solver.html

Can you post your model to http://www.grasshopper3d.com/group/geometrygym/forum/topics/autodes... (a good idea to collate the discussion there) or let me know if it's one of my examples?

Hello Jon,

Your example works. My model works now also but doesn't give any result. It takes a long time (relatively) to export and to get results (probably related to the numbers of elements to export, calculation itself is very fast in Robot).

I posted my model to the link given in your message.

Deat jon,i just learn a little about you plug in,and very interested,now i need you licence and some examples.
Thanks o lot!

ssIFCSS does not work,when space curves import or the result is not i wanted.

Hi,

there are some wrong about this

test.3dm

test.gh

Hi,

There are some problems. Need help! The close curve extended is not the solid.test2.gh

test.gh

Your first example there is 2 sectioned spine components.  The other one produces a better result.  Refer attached.  

For the second file, you are using the "Surface" component, if you use Extruded area solid you will get the caps.

test2.gh

I think it's better to put the questions into a discussion thread.

jon,is there a way to export revit files to IFC4?

Hi Mehdi,

Not directly yet.  Most software companies are saying it will take them a year or two to implement IFC4.  What do you want to import IFC4 into?  I could provide a converter (but it won't necessarily take advantage of the improvements).

I am planning on developing my own exporter for Revit, but it's a low priority (most of the workflows at present are GH/?? into Revit.

Cheers,  Jon

so what type of IFC file work with plug-in ? 2*3 and 2*2 doesn't work fine

My plugin can use IFC2x3 and IFC4.  Many software generates "bloated" IFC files for "coordination" with polysurface representations (like a mesh) that Rhino isn't optimized for.  Can you post example file and description to this discussion (or email/skype me)? http://www.grasshopper3d.com/group/geometrygym/forum/topics/ifc-ind...

jon i export rac_basic_sample_project.rvt ( one of sample project) to IFC2x3 and i saw this

Can you please email me the IFC file you created?

what's up about a problem i mentioned ,jon?

Hey Jon,

I was trying to take a look at the Waffle Example from your blog under the 

GH to Archicad (OpenBIM IFC) Section

And I got a missing plugin error when i tried to open it. It said that it was sdrConvCurve. If you could let me know what I am missing that would be great. Thank you!

Hi Michelle,

Bullant was previously known as "StructDrawRhino" (SDR).  If you install it from http://www.geometrygym.com/downloads it should fix the error.

Thank you.

Hey Jon

Im having a slight problem while playing with the Tesselation tool. when the size of tessellation is over about 3500 a object reference not set error occurs. The target brep is an untrimmed surface measuring 15000 by 100000 (mm) and the tessellation type is weaire phelan. Ive tried a fex different breps and all fail to create the tesselation. Any ideas on how to set up for larger tesselations.

Thank you.

Hi, Jon, I am a student learning grasshopper recently. Now I am trying to download the Geometry Gym but it asks me to email the administrator. Could you help me?

Hi Yuke,

If you send the email, I'll validate the license file (I work full time on the development and support of the tools, so a licensing system is in place).  

Jonathan, can you email me with a sample model so I can take a look at this?  It might be document tolerance coming into play.

Hi1 Does anybody know how to create windows and doors simple and nice within GeomGymBIM environment?

THX

i m not getting any reply for my Geometry gym license email.

Please respond

Hi There,

Does anybody know that how I can have geodesic dome? I used StrucDrawRhino but it always gives me the sphere and if i cut it from middle of the sphere (to get dome) all of my hexagons in the middle will split randomly and they don't have the specific size . I want to have exact geodesic DOME (not sphere) with the exact same size of hexagons. I want to 3d print it and I really do not want to have many different sizes of hexagon . I want minimize the variation by using one type of hexagon and one type of pentagon or just one hexagon or 2 different types of hexagon. I am attaching the sphere and dome image to this post. as you can see in the image in the dome one the hexagons are cut randomly. I am wondering if there is a way that the hexagon can start exactly from the bottom of the dome.

I really need it for my school project and I will appreciate  quick responses.

Thanks

Hi Mona,

If you look at the dome in elevation, you can see splitting into a hemisphere won't get you integral shapes.  If you can split above or below (as indicated on attached image) shapes will be rational but some will be halved.  Not sure if this helps or not.

Thank you Jon for your response. I did the same.
