(API) Addin for coping loads for Load Cases

Anonymous — Sun, 04 May 2014 09:12:04 GMT

Hello, everybody!

Sometimes if you have an array of loads and need to transform of copy them - for example, change direction, change values.

In this case you can use table editor, but it's not very quick way in case of different load types.

So, I've tried to make an add-in to ROBOTIZE this procedure. With this application you can copy loads from one Case to another.

Some features:

1/ To invert the direction of loads you can use negative factors

2/ In general it's not recommended to activate Check Box "Include Auto Generated loads", because in some cases it can cause doubling of loads (Loads + Auto Generated Loads).

3/ But you can use this option to convert loads on bars from cladding into usual trapezidoidal loads (setting factor for panels = 0). But before you have to intersect bars with each other.

Screenshot below represents the results of AddIn using.

Please notice that you have to unzip whole folder before using this AddIn

As always: feel free to download and use, comments and modifications!

Very cool, Igor!

Could you modify this add-in please? It will be great, if user will has the ability to copy only Auto Generated loads to the new load case. Or maybe ability to convert all Auto Generated loads to standard load in the same load case. I think it will be useful when the model goes from Robot to Lira\SCAD.

Very cool, Igor!

Hello, Roman!

Why not :-)? I think it will be useful modification, I will try to make it soon!

Very cool, Igor!

Roman, I'm afraid there may be difficulties - unfortunately Auto Generated loads have blank Object property (API)

Just awsome Igor, like usual.

do you think is it possible to make the copy only for a specific selection of bars, pannels or nodes?

I'm currently training to code using C# and the API, if you tell me where I shall search to modify you addin, I'll be keen on doing that.

Have a nice day.

OF course it is possible 🙂

Use Exclude, And or ExcludeText or AndText on Selection

Addin added to our list

Thank a lot, Thomas!

Rafal was absolutely right - the best way to modify the add-in is to find the active selection firstly and then use logical operation between selections (.And, .AndText, etc) to check if objects from load list belongs to this selection.

For example, for Node Load you firstly have to get an selection:

RobotSelection nSelection = robapp.Project.Structure.Selections.Get(IRobotObjectType.I_OT_NODE);

And then if this selection not empty you can modify object list for the load in this way:

IRobotLoadRecord toRobotLoadRecord = rToSimpleCase.Records.Create(rRecType);
RobotSelection toRobotSelection = robapp.Project.Structure.Selections.Create(IRobotObjectType.I_OT_NODE);

toRobotSelection.FromText(fromRobotLoadRecord.Objects.ToText());

toRobotSelection.And(nSelection);
toRobotLoadRecord.Objects.Add(toRobotSelection);

Hello, everyone,

I have slightly updated this Add-In.

So, new features in program

1/ Loads coping for a part of structure - it depends from active selection.

2/ Now it possible to copy Auto generated loads - you can copy only Native loads, Native and Auto Generated loads and Auto generated loads. But in any case I can't recommend to copy autogenerated loads.

Thank you for the add-in Igor.

Although I have one question, how do you select several loads? Like to select the loads you want to copy.
Whenever I get my cursor on the arrow of a load, it becomes blue and I can right click to change this one load, but as soon as I move the cursor, the arrow goes pink again. Left clicking doesn't select anything.

Could you please add a screencase video on how to use it ?
