(API) Translate whole structure

[JacquesGaudin]

I am trying to translate the whole structure using the API. 

My initial idea was to select all nodes with `Structure.Nodes.CreateFull()` and then use `Structure.SelTranslate` but this doesn't translate any of the nodes.

So far the workaround I found is to iterate over the selection and move all nodes one by one with `Structure.TranslateNode`. This takes a long time however.

Is there a way to translate all nodes at once?

Hi @JacquesGaudin 

It works on selection "in Robot" - by Get.

Example:

Set sel = RobApp.Project.Structure.Selections.Get(I_OT_NODE)
sel.FromText "All"

RobApp.Project.Structure.Edit.SelTranslate 15, 0, 0, I_TO_COPY, 1

Thanks @Rafal.Gaweda  it works indeed. What is the difference between `CreateFull` and `Get` + `FromText('all')`? 

I find the API reference a bit obscure when it comes to selections.

Hi @JacquesGaudin 

Create... methods create selections in API to work with API. These selections are not visible in Robot.

Get - get selections from Robot \ model. You can Get even empty selection and the fill it as You like. 

NOTE: playing with selections Got from Robot may be more time consuming as Robot will refresh them (display of them) on display \ model. 

So

Dim sel As RobotSelection
Set sel = RobApp.Project.Structure.Selections.Get(I_OT_NODE)
sel.FromText "All"

gives the same effect as

Dim sel As RobotSelection
Dim sel1 As RobotSelection
Set sel = RobApp.Project.Structure.Selections.CreateFull(I_OT_NODE)
Set sel1 = RobApp.Project.Structure.Selections.Get(I_OT_NODE)
sel1.FromText sel.ToText

or

Dim sel As RobotSelection
Dim sel1 As RobotSelection
Set sel = RobApp.Project.Structure.Selections.CreateFull(I_OT_NODE)
Set sel1 = RobApp.Project.Structure.Selections.Get(I_OT_NODE)
sel1.Clear
sel1.Add sel

Thanks for the explanation @Rafal.Gaweda, that makes perfect sense. I wish there was a few examples like this in the documentation.

Dear all,

How to combine nodes and bars in the same selection?

Thanks a lot

What are you trying to achieve? You may have better luck posting a new question.

If your problem is related to translating elements in the structure, moving the nodes will move the bars too since the bars are defined with a reference to the start/end node numbers.

Thanks @JacquesGaudin ,

My issue is in SelRotate command (similar than SelTranslate).

The thing is when I rotate my structure by selection of nodes, all bars are translated properly but the Gamma angle is not changed (is the same value than with no rotation), therefore I need rotate all my nodes and bars at the same time, so that this gamma is updated.

I've tried it with I_OT_OBJECT and the process is OK, but there are some isolated node that is not rotated.

Thanks for your comments.

If I remember correctly, ``SelRotate`` operates on the selection in Robot's window (the one you can actually see on the screen) which is a IRobotMultiSelection. The following should work to select bars and nodes and apply a rotation to them.

Set selNode = RobApp.Project.Structure.Selections.Get(I_OT_NODE)
selNode.FromText "All"

Set selBar = RobApp.Project.Structure.Selections.Get(I_OT_BAR)
selBar.FromText "All"

SelRotate p0x, p0y, p0z, p1x, p1y, p1z, angle, options, repetitions

Thanks a lot @JacquesGaudin it works perfectly.

I was thinking that when the bars are selected the selection of nodes was lost.

Thank you.

I find this a bit confusing too but glad it works!
