I keep my script library in a folder in my Dropbox. In the Python editor options, I have set that folder path, and eliminated the default path :
...\AppData\Roaming\McNeel\Rhinoceros\5.0\scriptsDespite that fact, when I do a Save or SaveAs for the first time in a session, it reverts to that folder, like it was hard coded somewhere... Can you please fix?

Hello,
I am in the course of learning script example from Rhino 5 Python Primer regarding recursion.
I have a function written as below:
def AddArcDir(ptStart, ptEnd, vecDir): vecBase = rs.PointSubtract(ptEnd, ptStart) if rs.VectorLength(vecBase)==0.0: return if rs.IsVectorParallelTo(vecBase, vecDir): return vecBase = rs.VectorUnitize(vecBase) vecDir = rs.VectorUnitize(vecDir) vecBisector = rs.VectorAdd(vecDir, vecBase) vecBisector = rs.VectorUnitize(vecBisector) dotProd = rs.VectorDotProduct(vecBisector, vecDir) midLength = (0.5*rs.Distance(ptStart, ptEnd)/dotProd vecBisector = rs.VectorScale(vecBisector,midLength) return rs.AddArc3Pt(ptStart, rs.PointAdd(ptStart, vecBisector), ptEnd)In the line :
vecBisector = rs.VectorScale(vecBisector,midLength)I get an error message "SyntaxError: unexpected token 'vecBisector' ". Why do I get this message?

Right now it returns only the top level layer name, it would be handy to have the full path. This was already discussed awhile back here... so there are workarounds, but again it would be nice to be able to do this directly.

OK, lets say I have a set of hierarchical layers/sublayers (leave them empty for now), and I want to create a new parent layer and move the entire existing layer hierarchy under it:
I'm having trouble doing this - I thought it would be sufficient to get the full path name to each layer and then add the parent layer name to that at the front:
parentName+"::"+layerpathName, then add a layer to the document with that full path. But it doesn't work... Anyone have a logic for doing this?Thanks, --Mitch

Issue #1:
With a new blank file containing just one layer "Default"...
In vb Rhinoscript, run the following code:
Option Explicit Call TestAddSubLayer() Sub TestAddSubLayer() Call Rhino.AddLayer("Default::NewLayer") End SubThe layer NewLayer is added as a sublayer of Default.
Now, do the same thing with Python rhinoscriptsyntax (start with a new file):
import rhinoscriptsyntax as rs rs.AddLayer("Default::NewLayer")A new top-level layer is added with the name Default::NewLayer... Not how it's supposed to work IMO...
Issue #2:
In the file created in the first step above - with a Top layer "Default" and a sublayer "NewLayer" - put one object (anything) on the sublayer "NewLayer"
In vb rhinoscript run the following and choose the object:
Option Explicit Call TestGetObjectLayer() Sub TestGetObjectLayer() Dim obj : obj = Rhino.GetObject() Call Rhino.Print(Rhino.ObjectLayer(obj)) End SubReturns: Default::NewLayer
Now, run the Python equivalent and do the same:
import rhinoscriptsyntax as rs obj = rs.GetObject() print rs.ObjectLayer(obj)Returns: NewLayer
These sublayer issues are driving me nuts - making it very hard to script layer operations with sublayers in python rhinoscript syntax...
IMO, all rhinoscriptsyntax methods need to return the full layer path. Also, for both vb and python, optional arguments to return the layer ID instead of the name would be good.

Not sure if this was intentional or not, but I noticed when using the ExplodePolysurface method in Rhinoscript that the exploded surfaces would maintain their layer assignments but in the Python version the exploded surfaces go to the current layer.
Easy enough to work around, but I thought I would point this out.
Thanks,
Dan

I have noticed some inconsistency between how the command and rs method work.
With the command, no matter what types of object I preselect (mix of curves and objects that actually have render mesh) the command will work and extract meshes from whatever it can.With the RS method, when I feed it the array of mixed types, as soon as there is an element that doesn't have the render mesh (i.e. curve) the method will return Null. It would be more convenient and consistent if the command-like behavior was applied here too. Would it be possible to fix?
thanks~

I'm creating a small animation and for that I need to rotate things a lot of times - I have like 150 objects and they rotate around a center as well as around themselves, and the idea is to see the intermediate moves. This is eating up my memory very quickly. Programming ClearUndo in the loop doesn't seem to help.
Any way around this limitation? Otherwise I'm going to need to invest in more memory....

Been trying to use the CreatePatch method, but got stuck on its first parameter: IEnumerable(GeometryBase).
Seems like @stevebaer already gave an explanation on this issue in here.
Still I am not getting it.
Tried the following code:from System.Collections.Generic import IEnumerable from Rhino.Geometry import Point import rhinoscriptsyntax as rs import Rhino import System pt_ids = rs.GetObjects() pts = [rs.coerce3dpoint(pt_id) for pt_id in pt_ids] pointL = [Rhino.Geometry.Point(pt) for pt in pts] IEGB = IEnumerable[Point](pointL)got the following error message (one the last line of the upper code):
Cannot create instances of IEnumerable[Point] because it is abstractI thought that maybe a "conversion" of Point3d needs to be done, as Point class has been derived from GeometryBase. Is this causing the problem?

Hi,
I have a mesh and I am trying to split the outline of the mesh into two curves. This seems relatively simple using rs.splitcurve however this code:
Curves=rs.SplitCurve(Outline,(CuttingPoint1,CuttingPoint2))(where CuttingPoint1 & CuttingPoint2 lie in the domain of Outline)
gives me 3 curves. It seems like it is splitting the curve at the two supplied cutting points as well as the seam.
Additionally, if I try to move the seam to one of the cutting points:
rs.CurveSeam(Outline,CuttingPoint1)and then run the splitcurve as above, the curve does not split at all.
For now I am able to get around this by using the TrimCurve function twice however this seems inefficient, especially when it seems like the splitcurve function should achieve this.
Am I doing something wrong with the SplitCurve function or is this a bug?

I'm seeking for a way (with python) to list every singl object in document, even if there locked or hided or located in hided layers.
Any clues ?

Hi,
this is more a questions about aliases than scripting, but this seems like the place for it.
I am trying to work out if there is something that will work in an alias to allow me to wait for one command to execute (with a variable degree of user input) and then run another.
Specifically, I'd like to get this to work:
! _CurveBoolean _GroupSo that I can run the curve boolean command, do all my selecting and options or whatever, and THEN group the resulting curves.
I've tried PAUSE but that doesn't seem to make any difference.
Any help would be greatly appreciated.
thanks
Peter

Good morning colleagues,
So I could like an alias for starting a line at 0 in whatever view you happen to be in, so I wrote the following macro:
line startofline=0
... but it didn't work. It seems like it should be simple, but...
Any assistance would be appreciated.Thank you.

Just to say, i am usually on a Mac, but can do Windows if that works.
I am wondering if I can have a script to copy a folder of Rhino 5 files as version 4 files.
I have about 30 to do, and may have more every week or 2. Until I can convince the person to upgrade.
Thanks, Randy

I try to read the viewports from another file, but it doesn't work perfectly.
It does read in the active viewports, but none of these new names, NOR any of the other views stored in the read file can be found either in NamedViews or in "View - Set View".
Are there any workarounds to read in the views?
I try to import a file and have it act as if the file was "opened".
Or can I open a Read Only file with out the "this is a read only file" warning.
