Steel Design - Sections Ratios - API

[stathiseleftheriadis]

Hi,

I'm using the code below to run steel design verification for a group of beams. There is an error when I obtain the ratios. I've added a breakpoint and I'm getting a null value into rDimDetailedRes.

Does anyone what might be the problem?

Thanks.

Hi,

Thanks. It works fine now.

Do you also know how to avoid the window in the attached jpg through API?

Best,

Stathis

Maybe this way:

Thanks. I'll give it a go.

Hi,

Sending a message to the window it doesn't seem that easy to me.

Is there another way to skip Robot windows via API? I'm preparing a custom optimisation algorithm and I need to run a significant amount of runs/verifications in a recursive process.

Thanks.

Stathis.

Hi,

If You don't need any interactions with RSA You can switch off Interaction flag for the time of analysis:

Dim r As New RobotApplication
r.Interactive = 0
'some code
r.Interactive = 1

It should disable showing any of messages.

Many thanks.

I've been struggling with SendMessage but this works perfectly fine.

Cheers
