Select simple cases when printing tables

Jelle.Visser — Tue, 14 Feb 2023 11:24:41 GMT

I'm trying to select only the simple cases before I print my reaction forces to csv.

However, reading through the documentation, I do find options to create cases, but I do not find a way to select a case for a table. I loop through the tables, and certain ones are "printed" to csv. However, now Reactions are all cases, I only want simple cases.

I tried to implement a solution given by @Stephane.kapetanovic

https://forums.autodesk.com/t5/robot-structural-analysis-forum/api-robot-vba-activate-or-select-load-case/m-p/10890468

However, this does not seem to work. I would prefer to just the loadcase just for one table, because for the stresses and ratios I do want the combinations to be included.

Dim ViewMngr As IRobotViewMngr Dim ActiveView As RobotView Dim CaseSel As RobotSelection Dim ActiveViewNumber As Long ViewMngr = RobApp.Project.ViewMngr For k = 1 To ViewMngr.ViewCount If ViewMngr.GetView(k).Window.IsActive = -1 Then ActiveViewNumber = k : Exit For Next k ActiveView = ViewMngr.GetView(ActiveViewNumber) CaseSel = ActiveView.Selection.Get(IRobotObjectType.I_OT_CASE) CaseSel.FromText("Simple Cases") ViewMngr.Refresh() Console.WriteLine("Selected Simple Cases" & vbCrLf)

Now it crashes on line 10 (line 198 in the full script) with the message:

System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.

hi @Jelle.Visser

the context is not the same

you confuse the selection of preliminary load cases to a parametric view with that relating to tabulated results

Ah yes, I assumed I was doing something wrong.
Can you point me in the right direction for selecting the active cases for tabulated results?
The documentation doesn't seem to have a clear solution, or at least I'm not seeing it.

@Jelle.Visser

ok,

can you give me the full code?

The extract communicated concerns only the blocking point but it is not what you want.

I can't paste the entire code here, that would be a bit long, but here is the repo:
https://github.com/Tebulo-Engineering/RobotAPI

The place where I tried to set the load case is line 189-201, and I print the reactions to csv on line 284 and onward

hi @Jelle.Visser

each RobotTable has a function Select that can accept for first IRobotSelectionType and for second parameter a string that could contain load cases
Ex : MyTable.Select I_ST_CASE, "1 2 3 ... "

Best regards

Now when I add the following line after the if statement to check if it's the reactions table, it doesn't output any reaction csv anymore at all.

tf.Select(IRobotSelectionType.I_ST_CASE, "1 2 3 4 5 6 7 8")

Do note that I am programming in VB.NET, seeing your code, I assume that's vbs/vba?

The first 8 cases are the simple cases, so that's what I'd want to select, but as long as it works, it shouldn't be hard to change it.

hi @Jelle.Visser

tf refer to RobotTableFrame

Select method is part of IRobotTable interface

t is RobotTable and come from tf RobotTableFrame by method Get

Imports RobotOM.IRobotSelectionType '< at beginning [...] Dim t As RobotTable Dim tf As RobotTableFrame t = tf.Get(j) t.Select(I_ST_CASE, "1to8") ' equivalent to IRobotSelectionType.I_ST_CASE

note that you can select bars by same method

t.Select(I_ST_BAR, "1 2 3 ...")

Thank you, that works!
