Rhino doesn’t update changes I make on my Python scripts not until I close and re-open Rhino before the changes are recognized. Any possible solution to this?

PointCloud commit changes (or replace) causes RAM usage creep?
@nathancoatney wrote:
I am building large-ish point clouds and updating the document periodically to show progress. I have noticed Rhino using excessive RAM if I use Rhino.DocObjects.RhinoObject.CommitChanges() (also scriptcontext.doc.replace()). The RAM creeps up as the point cloud is updated, and is never recovered after the script completes, or even if everything is deleted from the document.
This script demonstrates the behavior using two different methods to build the point cloud. Run either function and watch RAM. I’m hoping someone can give me a hint on what is going on. If not I’ll try a conduit.
Thanks.

Change "Display Colour" to "By Parent" within multiple files Via Script
@leigh.anderson wrote:
Hi,
I am new to Rhino and I am looking for some assistance.
I’ve got 1489 Library items which have “Display Colour” set to “By Layer”, when I insert any of these items into a model as a block they keep their original colour. I was hoping that someone may have a script which will run through all the Library files and change “Display Colour” to “By Parent”.Many thanks

Getting a component to watch a point
@matthewaustin233 wrote:
Bit obscure, but how does the point parameter component actually work?
i’ve got a point in Rhino and I have a python component that queries it and returns its attributes - however, when the point is moved or changed, this doesn’t signal the component to recompute - which makes sense, cause I haven’t asked it to. Is there a way to do this?
I.e. Is there a way to embed the point parameter components ‘listener’ functions in a custom python component?
Thanks in advance.

Count self intersection for a curve Grasshopper/Python
@claire.dumont wrote:
Hi everyone,
I’m trying to find the number of occurrences of self-intersections for a curve in Grasshopper but I don’t understand why some points aren’t taken into account in my occurences list.
I used Curve|Self (CX) to find the intersections and then count() in Python. For instance, points “2”, “15” and “37” are the same, but, python find 1 occurence for point 2 and two occurences for 15 and 37 (and not 3 for the three points !).
Do you know this problem?
How do I find the self intersection of the curve and right occurences by using Grasshopper and/or Python?Thank you

Save multiple file to Rhino 5
@banati.bodo wrote:
Hi there!
I’m totally new with rhino/pythonscript, apologies if i ask something obvious.
My problem is the following:
i have a grasshopper file, and in the end i bake multiple objects into different .3dm files with lunchbox.
the problem is, i need these files to be in rhino 5 version instead of rhino 6. i found no solution for this in grasshopper, so i figured it may could be solved with rhinoscript.
it should open files from a folder, and save them as version 5 .3dm.
is it possible to do this in rhinoscript / pythonscript? can someone point me in a direction to start with this?
thanks in advance

Laying out contours for laser cutting with Python
@lmboyer04 wrote:
So I’m still fairly new to this all so pardon if I’m asking bad questions. I’m using Rhino Python Editor and I’m trying to create a script (while also learning to script a bit) that will essentially contour any closed polysurface model at an interval of choice, Orient the curves to the C plane or some other plane so they are all together (as if I ran Make2D) and then arrange them so that they are in a line, in order, with a small gap between them.
It gets really messy with the whole organizing of object IDs in the big for loop… I gave it a shot tho.
I can already see there are some sloppy workarounds not to mention just some stuff that just isn’t working… but I just dont know the alternatives. Please provide any ideas you have for bridging the gaps and/or cleaning it up
Thanks so much!

Python Script for AddPolygon?
@lbrooks wrote:
I’m just getting started with rhinoscriptsyntax, and I’m wondering how come there isn’t a function for AddPolygon like there is for AddRectangle and AddEllipse? Am I missing something?
If there isn’t a native function in the library, has anyone written a script for this? (Yes, I am lazy).
Thanks a lot!

Grasshopper Python SubD script (got getsetter_descriptor)
@h.h.c.manders wrote:
Hey all,
I have been playing around with Rhino 7 and it’s SubD possibilties. To make the modeling easier I have been trying out to generate the SubD from a mesh through Grasshopper python. One of the functions within Rhino ToSubD is to InterpolateMeshPoints. I wanted to try this within Grasshopper as well however when I define the SubDCreationOptions and call InterpolateMeshVertices I get a getsetter_descriptor error.
Specifically:
Runtime error (ArgumentTypeException): expected SubDCreationOptions, got getset_descriptor
Script:
import rhinoscriptsyntax as rs
import Rhino.Geometry as rggeometry = rs.coercemesh(x)
options = rg.SubDCreationOptions.InterpolateMeshVerticesa = rg.SubD.CreateFromMesh(geometry, options)
Any one has experience with this?

Slicing a list at integer of when an element is different from the previous
@aeaechan96 wrote:
0
I need to be able to slice a list of points into multiple sublists, to act as a guide for slicing another list.
My list right now is y_vals = [a,a,a,a,a,a,b,b,b,b,b,b,b,b,b,b,b,c,c,c,c,c…] and I need it to slice every time the number changes. a, b and c are actual numbers, but the numbers are rather long, so I typed it out in a,b,c.
I wanted to use the slicing method of [:x], but it’s a list of 5000 over numbers, and I’m not sure how to slice a list. Thank you in advance!

How can I move a point through out a custom plane's z axis
@joantomass wrote:
Hi all,
I’m quite new on python scripting and I’m getting stuck with the tansformations, since I’m trying to move a point though a custom plane’s z axis to make then a line and I have no clue on how to manage the transformation.
I know how to do it with gh components, I just deconstruct the plane and then move the point applying the “amplitude” component through the z vector, but how can I translate that to python ?
I’ve been searching in the forum and it seems to me is not an easy thing.
Can someone explain that for a gh python rookie?Thanks in advance ,

ObjectClash only working for extrusions

I’m trying to adapt the example ObjectClash script - Rhino3d Object Methods - Object Clash - but the only geometry type that I can get to work are Extrusions.
