How to fast select all arcs in a drawing

hi,

wich command do I use in rhino to select all the arcs in a drawing, because I want to put them in a different layer.
The same for circles

thanks
edward

Hi Edward- here is an ancient RhinoScript that may help- save, unzip, then drag and drop the rvb file onto Rhino to add the following aliases-

SelArc
SelCircle
SelArcRad (by radius)
SelCircleRad

SelArc (2).zip (880 Bytes)
Does that do anything useful?

-Pascal

Thanks
I already found something and that was the same solution, I think also from you.
only drag and drop isn’t working.
I have only to open rhino 4 and than drag it into?
edward

Hi Edward - that should work- Unzip, save, and then drag and drop from the saved location (not from the zip file) onto Rhino… any luck?

-Pascal

not in a certain directory, map?

In the past I did devsrf into rhino but that is a .rhp file

Hi pascal
thank you very much .
it is working.
is there a list of rvb files, for the future??
did you see my other question of this day?
regards edward

Hi Pascal,
I can’t download the script anymore and I can’t get it working in Rhino6
happy new year
Edward

Try this one?

SelArc.py (466 Bytes)

Is this one also for circle’s?

No, circles are considered separately (by me anyway) Below is a recent post with several “objects by type” selection scripts.

Hi Pascal, just wondering if this script (at the start of the thread) is still available somewhere as the current link seems to be invalid?

SelArc
SelCircle
SelArcRad (by radius)
SelCircleRad

Cheers
Alex

Hm. I cannot find it - I’ll make some more.

Thanks Pascal.

Seems they are just the scripts we are looking for.

Cheers

@alexbabaeff - see how this works for you- I shoved it in with a bunch of other curve utlities in this plug-in:

CurveAndArcUtilities.rhp (61 KB)

You’ll need to unblock the rhp in Windows, then drag and drop it onto Rhino. It has a bunch of commands, some of which might be useful

3PtArcFromPoints
3PtArcFromPolyline
ArcFitToCurve
ArcFitToPoints
ArcFitToPolyline
RadiusFrom3Pts
SelArc
SelArcByRadius
SelCircle
SelCircleByRadius
SetArcDegrees
SetArcRadians
SetCurveLength
SubCrvFromMid

Awesome, thanks Pascal

I also have two commands for selecting arcs and circles that I found in this forum several years ago. You just need to paste these into the “Command” filed of the icon:

Tooltip:
Select arcs

Command:

! _NoEcho _-Runscript (
Option Explicit
Call SelArcs()
Sub SelArcs()
	Dim arrAllObjs,strObj,entity,i : i=0
	arrAllObjs=Rhino.NormalObjects
	If Not IsArray(arrAllObjs) Then Exit Sub
	Call Rhino.EnableRedraw(False)
	'Call Rhino.UnselectAllObjects
	For Each strObj in arrAllObjs
		If Rhino.IsArc(strObj) Then
			Call Rhino.SelectObject(strObj)
			i=i+1	
		End If		
	Next
	entity="arc"	
	If i<>1 Then entity=entity&"s"
	If i>0 Then		
		Call Rhino.Print(i&" "&entity&" added to selection")
	Else
		Call Rhino.Print("No "&entity&" found, nothing added to selection")
	End If	
	Call Rhino.EnableRedraw(True)
End Sub
)

Tooltip:
Select circles

Command:

! _NoEcho _-Runscript (
Option Explicit
Call SelCircles()
Sub SelCircles()
	Dim arrAllObjs,strObj,entity,i : i=0
	arrAllObjs=Rhino.NormalObjects
	If Not IsArray(arrAllObjs) Then Exit Sub
	Call Rhino.EnableRedraw(False)
	'Call Rhino.UnselectAllObjects
	For Each strObj In arrAllObjs
		If Rhino.IsCircle(strObj) Then
			Call Rhino.SelectObject(strObj)
			i=i+1
		End If	
	Next
	entity="circle"
	If i<>1 Then entity=entity&"s"
	If i>0 Then		
		Call Rhino.Print(i&" "&entity&" added to selection")
	Else
		Call Rhino.Print("No "&entity&" found, nothing added to selection")
	End If	
	Call Rhino.EnableRedraw(True)
End Sub
) 

@Rhino_Bulgaria If you are going to post code, it’s best to format it so that people can copy/paste it correctly so it’s usable. To do so, enclose the code with 3 “backticks” above and below like this:

```python
<paste your code in here>
```

Adding the python label will also format it with more less standard python formatting and colors; there are labels for most common languages.

The scripts above are mine - old .rvb scripts which will only run on Windows - but since Pascal already posted his in a plug-in I didn’t post them in this thread. Here are the python equivalents:

SelArc.py (466 Bytes)
SelCircle.py (474 Bytes)
SelSameRadArcsCircles.py (3.0 KB)
SelByRadius.py (2.8 KB)

Thanks! I didn’t knew about the Python special code. Seems to work now in my edited post above. :slight_smile:
By the way, your scripts for selecting arcs and circles are priceless and I use them quite often.

As the old scripts are written in vbscript, which apparently the version of Markdown used here does not support the syntax highlighting, you can just leave off the python label…

```
<code>
```

Then it looks like this:

Option Explicit
Call SelCircles()
Sub SelCircles()
	Dim arrAllObjs,strObj,entity,i : i=0
	arrAllObjs=Rhino.NormalObjects
	If Not IsArray(arrAllObjs) Then Exit Sub
	Call Rhino.EnableRedraw(False)
	'Call Rhino.UnselectAllObjects
	For Each strObj In arrAllObjs
		If Rhino.IsCircle(strObj) Then
			Call Rhino.SelectObject(strObj)
			i=i+1
		End If	
	Next
	entity="circle"
	If i<>1 Then entity=entity&"s"
	If i>0 Then		
		Call Rhino.Print(i&" "&entity&" added to selection")
	Else
		Call Rhino.Print("No "&entity&" found, nothing added to selection")
	End If	
	Call Rhino.EnableRedraw(True)
End Sub

That’s the best I think you can do with vbscript here, it would be nice if it looked like this though:
