Steel Bar Fire Design parameters [SOLVED]

General Discussion
1

Hi @MarcoPelle !
Is there a way to set up fire design and fire autodesign parameters for steel bars in Grasshopper? I didn’t see a corresponding row in the cfg file.

Thanks!

Hi @raidoschiff :slight_smile:
I have moved your question to a different thread so that we can help other users :slight_smile:

I do attach a cfg.xml file where some steel fire design setting can be modified. Unfortunately, it is not a fully tested feature and, therefore, something might be not working properly or some of the setting might be missing.

cfg_fire.xml (3.7 KB)

Thanks for the quick reply, @MarcoPelle!

How should I use that cfg file?
Can I add it to the general steel design cfg file and load that or should I load the cfg files separately?
Which of the values should I change to “design” the critical temps of the bars? Or can I somehow export a similar cfg file from Fem-Design to see the values myself?

Happy to help @raidoschiff

It is a bit advance as a feature so it it not really well documented.

try to do the following:

  • Open FEM-Design
  • Copy the following text
    ; CXL MODULECOM WXMLCFG:C:\temp\cfg.xml
  • paste the text on the FEM-Design command bar

The procedure will create a cfg.xml file in the folder temp. Make sure to have the folder on your machine or specify a different one.

The command will write the current setting on a text file and you should be able to understand what you can specify.

When you have those value, you can use one of the method specified below to use them in the software.

Let me know if everything is clear. :slight_smile:

Hi @MarcoPelle!

I think I got the cfg_fire file changed as needed. Thanks for the secret-command trick :slight_smile:

But seems like it’s not reading that cfg_fire file even though it’s correctly referenced.
I tried the FEM-Design.SetCfg node in two locations, but it still seems to be taking some other default values into the created model.

Am I doing something wrong or what could the issue be?

Have you tried in plug-in the setCfg just after OpenModel ?

Can you please share you script so that I can test it out ?

As I said, tunfortuantely, his feature has not been used and fully tested YET so it might have some bug

Hi @MarcoPelle!

Yes. I tried setCfg just after OpenModel too.

Here’s a link to the script and the cfg file I edited. These are not for sharing with the public :slight_smile:

@raidoschiff
Thanks for spotting a bug :slight_smile:

The component is reading the file at the following filePath. It does not matter what we give, it always read at this point.

For the time being, put your file in that specific folder and it should work :slight_smile:
