RhinoScript - responding to command prompts & pausing refresh

Scripting
,
1

I have a RhinoScript in which I create an array of points, select them (in code), execute MeshPatch to convert them to a mesh, select the new mesh, then execute ToSubD. The code looks like this after I’ve generated the points, which are in an object array named “arrPtObjects”.

Rhino.UnselectAllObjects
Rhino.SelectObjects arrPtObjects
Rhino.Command _MeshPatch
(need something here to address MeshPatch prompts)

Rhino.UnselectAllObjects
Rhino.Selectobject Rhino.FirstObject
Rhino.Command _ToSubD
(need something here to address ToSubD prompts)

Rhino.DeleteObjects arrPtObjects

Question 1: How can I respond in RhinoScript to the parameters prompts resulting from the MeshPatch and ToSubD commands? I’ve tried searching help docs for this and tried what I found, but nothing worked. The way it works now, the user must respond to the prompts for the code to continue.

Question 2: My point generation is rather time consuming. Is there a way to pause viewport refresh then restart it after the point generation is done?

Use directly the Rhino.MeshPatch command instead of calling the Rhino.command
About the “ToSubd” command I don’t see a function in VbScript… maybe in Pythonscript…
If you use the Rhino.command _ToSubD you can specify the options you need
UseMesh=ControlPoints MeshCreases=No MeshCorners=No UseSurface=Location SurfaceCorners=No DeleteInput=No
and call Enter at the end.

Rhino.EnableRedraw ([blnRedraw]) will enable/disable the screen redrawing (this will save a lot of time)
Another thing that can save time is to disable echo from the command prompt when Rhino.command is used

Rhino.Command (strCommand [, blnEcho])

strCommand - Required. String. A Rhino command including any arguments.
blnEcho - Optional. Boolean. The command echo mode. If omitted, command prompts are echoed (True).

Thanks, most of that worked. But for the ToSubD I still ran into difficulty. I tried both all in one line and two separate lines, but neither worked to address the prompts. Please advise the proper syntax:

Rhino.Command _ToSubD ControlPoints MeshCreases=No MeshCorners=No UseSurface=Location SurfaceCorners=No DeleteInput=Yes

Rhino.Command _ToSubD
Rhino.Command UseMesh=ControlPoints MeshCreases=No MeshCorners=No UseSurface=Location SurfaceCorners=No DeleteInput=Yes

You should write all the options on the same line as a text delimited by commas:
Rhino.Command “_ToSubD _Enter”
If you need to have some options specified or different from standard ones, add them after the _ToSubD:
Rhino.Command “_TosubD _DeleteInput=Yes _Enter”
Usually I specify all the options only to be sure that the command works always in the same way.

Perfect, thank you. Will SubD commands be added to RhinoScript at some point?

You’re welcome.

Don’t think that VbScript will be updated in the future.
At the moment (if VbScript isn’t enough) I suggest to move to Python Script that is a newer language and more powerful.
Cheers.
