(API) Changing the bar type

dagmaraxf — Wed, 04 Aug 2021 18:53:15 GMT

Hi,

How can I change the bar type using the API (please see the screenshot below)? I have already created bars in the project whose type is "N/A" and I would like to have a RC beam. Do I have to create a beam instead of a bar at the beginning?

I would appreciate your help.

hi @dagmaraxf

type (Steel beam EC3) is used for design.

' with Bar as RobotBar and Existing Label "Steel beam EC3" (to be created in other case) Bar.SetLabel IRobotLabelType.I_LT_MEMBER_TYPE, "Steel beam EC3"

Best regards

Note that this also works for R / C types

Bar.SetLabel IRobotLabelType.I_LT_MEMBER_TYPE, "RC Beam"

@Stephane.kapetanovic

Yes, you are absolutely right, thank you. I was confused by the mention in the API: Member type for steel/aluminum and timber design.

Hi @Stephane.kapetanovic maybe you know the solution to my next problem. I would like to change the settings of Calculation Parameter Definition.

I try :

structure.Labels.GetLabel(IRobotLabelType.I_LT_MEMBER_REINFORCEMENT_PARAMS, "standard").Data but gets an error. However, with the same syntax only with "I_LT_MEMBER_TYPE" the code works. Is there any other way to access these settings?

Thank you for your help, I have already studied the links and my calculation of the required reinforcement works. However, while "bars.Get(1).SetLabel(IRobotLabelType.I_LT_MEMBER_REINFORCEMENT_PARAMS, "standard")" works fine, I don't know how to modify the "standard" parameter set (or create a new one, "Create" does not work). I think I should refer to "IRBestCalcParamsDataDoubleValue" but I don't know how.

Hi @dagmaraxf

Could you upload the code of the creation of bars, including how you assigned section, material, and releases?. Currently I am trying to create bars with version CPython3, I just managed to create bars but tey are missing the properties. Thank you in advance.

Best regards,

Stefany

Hi,
Sorry it took me so long to write back. I am inserting the code.
