Robot API + Dynamo undefined warning

[milczarekuba]

Hello

I got a problem with using Robot API in Dynamo. I am trying to set bars as a trussbars, but when I running graph for a first time I am getting warning like below, when I add for example new line in any place in python script and run graph for a second time it works. I have no idea what is going on, I'd be greatful for some help.

@Rafal.Gaweda You helped my couple of times, I hope you will solve my problem also this time.

Thanks for any help.

@milczarekuba 

are you using the bar functions from the structural analysis package?

what i found in my scripts is that the python nodes are way quicker than the build in nodes of the package. 

(that's why i create my scripts full python.)

but what you can try is to use: application.Project.ViewMngr.Refresh()  on line 19 before you get the bars.

or use waitfor,passtrhough nodes.

Hi @1234eddie 

It might be like that.

Hint : I remember, once I discovered that user script (located  let say in the middle on graph) was executed at the beginning , not waiting for any input data. The solution was either to write "half" of Dynamo routine (everything before script + user script) as one script or make user node from this user script.

It do not work ;( I tried also time.sleep() as well. No idea what is going on

@Rafal.Gaweda 

Now  I discovered that when I put this node after calcualations it works perfect, but I need to set TrussBars before Calculations. Do You have any ideas to deal with it? I do not want calcualate project two times because this script is part of Optimo optimizing script and I calculate about 30k versions of my structure, so time is very important for me.

 @1234eddie I tried to generate whole structure by API but I got few basic problems, now I only write some functions in python when Structural Analaysis for Dynamo do not have nodes that I need. If You can share some basics scripts I'd be greatful.

Check out the topic's I have created over the last year's. And also on the dynamo forum(same username).

Most of them will have the dynamo as attachment.

If you have other questions let me know.
