Hi-

In the python code below I try to suppress the echos on the command line but it still shows the “command:” echo.  
Is it possible to suppress this aswell?

```auto
##################################
import rhinoscriptsyntax as rs
import Rhino

def MergeEdge():
    ArrObject=rs.GetObjects("Select Parts",16)
    rs.EnableRedraw(False)
    for srf in ArrObject:
        rs.Command("_MergeAllEdges _SelId "+ str(srf) + " _Enter",False)
    rs.EnableRedraw(True)
if __name__ == " __main__":
    MergeEdge()
#####################################

```

Try preceding the command name with `_NoEcho`.

Hi Dale

It Didn’t work.  
I modified the commanline but still the command echo appear.

rs.Command("\_NoEcho \_MergeAllEdges \_SelId “+ str(srf) + " \_Enter”,False)

See attached files

I am not seeing anything echoed to the command line, other than the `Select Parts` prompt.

What am I missing?

I’m seeing the same as Nico.

A `Command`: is printed for each repeat of the loop.

Also, an additional `Select Parts. Press Enter when done:` is printed after Enter is pressed.

For example, after window-selecting 4 surfaces at once and pressing Enter, this is printed:

```
Select Parts:
Select Parts. Press Enter when done:
Select Parts. Press Enter when done:
Command:
Command:
Command:

```

@Nico_de_Meester  
A workaround is:

```python
def MergeEdge():
    ArrObject=rs.GetObjects("Select Parts",16,select=True)
    rs.EnableRedraw(False)
    rs.Command("_MergeAllEdges",False)
    rs.UnselectAllObjects()
    rs.EnableRedraw(True)

```

Hi Dale

I got the same as what Steve showed.  
When you want to merge for example 100 parts you probably got 100 Command: lines in the history.  
But the workaround off Steve works.  
So I am happy.  
Thanks for you reactions.

Nico
