Hi,
I a new newbie and wonder if Rhino script (in python) could achieve what I want:
I have a 2d polygon surface (generally 4, 5 sides) and I would like to generate all the possible rectangles having a set of constraints:
- that fil within the surface of the area
- having a mininum width/height
that touch one or several sides.
rendering/visualizing the K generated possibilities?
Is Rhino Script the right tool for that?
Thanks in advances
Nicolas

I have a modeless tool window that I want to float on top of the Rhino Main window at all times.
I tried using the form.TopMost property, but realized that this made the dialog sit above EVERY application window even when switching to something other than Rhino.
I have read that the way to do this is to set the Form.Owner property to be the main rhino window, and to this end have tried using the following code:
my_modeless_form.Owner=System.Windows.Forms.Control.FromHandle(rh.RhinoApp.MainWindowHandle())
Unfortunately, this seems to always return None.
I understand that Rhino is built on C++ and not windows forms directly, but is it possible for me to get a .NET Windows Form "version" of the main window?
edit: It seems to work when I do the following:
my_modeless_form.Show(rh.RhinoApp.MainWindow())

DEFINITION
"Self-contained Scripting" or "Autonomous Scripting"
Creating a script which,apart from the initial input, can run to completion
and produce and/or modify an object in a pre-determined manner without additional user input.(An example of the application of such a script would be to produce a representation of a steel beam.)
PROBLEM:
When trying to use CreateRailRevolvedSurface in the Autonomous Script listed below I get following error message:
"expected Curve, got Guid"
The first two are curves, the third is a line and the fourth boolean?Parameters required by CreateRailRevolvedSurface
profile: Profile curve for revolution.
| rail: Rail curve for revolution.
| axis: Axis of revolution.
| scaleHeight: If true, surface will be locally scaled.
| Returns: A NurbsSurface or null on failure.When using AddSweep1 get error message "iteration over non-sequence of type Guid"
Question 1: How do I get Rhino.Geometry.NurbsSurface.CreateRailRevolvedSurface
to function in an Autonomous Script?
Question 2: How do I get rs.AddSweep1 to function in an Autonomous Script?import rhinoscriptsyntax as rs

Hi all,
I'm seeing something unexpected when deriving a class from Rhino.Input.Custom.GetPoint to override the OnDynamicDraw() method.
If the shadows are on, the solids show black sides.![]()
but all is fine without shadows
![]()
Here is the sample script that draws the cylinder
import Rhino import System def main(): gep = GetPushPullPoint() gep.AcceptNothing( True ) gep.SetCommandPrompt( '... Testing ...' ) gep.Get() class GetPushPullPoint( Rhino.Input.Custom.GetPoint ): def OnDynamicDraw( self, eventargs ): brep = Rhino.Geometry.Brep.CreateFromCylinder( Rhino.Geometry.Cylinder( Rhino.Geometry.Circle( 100 ), 100 ), True, True ) color = System.Drawing.Color.Cyan eventargs.Display.DrawBrepShaded( brep, Rhino.Display.DisplayMaterial( color ) ) main()Is there a way to avoid that ?
Am I missing something ?
Thanks

Hi All,
I have an object preselected. Then I do:
-_SelLayer _Pick
My previously selected object is still selected.
I hit enter.The selection does not change. I still have the initially selected object selected, but no other objects of the layer got selected. If I select the object inside the command, the other objects of the layer get selected as expected.
I would like the preselected object being used for the -_SelLayer _Pick. Can I adjust the macro to do so or is this not possible?
Thanks

Hi,
I would love to use the pyhull module in Rhino Python. But after some research I found out that the pyhull module needs the numpy module.
Here is the problem: numpy is not available for Rhino Python anymore, because numpy is not working with Iron Python.
Is that still true?
- Is there any other way to implement the pyhull module in Rhino Python?
Thanks a lot

Are there any rs."something" that dose the same as CreateRegions command in rhino?
If not, can I use the command to call the command:
import rhinoscriptsyntax as rs s = rs.GetObject("Pick a surface") rs.Command('CreateRegions' + " " + str(s), False) #know that this do not work, just a exampleLooking for answer that do not use any manual interaction, other that picking the first surface.

Hello everyone,
I have a simple quad mesh face and I want to retrieve the for normals of the vertices (shown in the Image) using c#. I used mesh.NormalAt(x,x,x,x), but this command as output gives me only one normal which seems to be the average of other for normals. Any idea?

Hi,
I’m working on a cleaning script.
My goal is to associate every annotation of my drawing to the “Default” style.This is the part of the script for simple objects (not in block):
def clean_annotations(annotations): annotations_nb=len(annotations) for i in range(0, annotations_nb): rs.DimensionStyle(annotations[i], "Default") clean_annotations(dim)It works : dimensions, texts and leaders style become “Default”.
I want to apply the same thing inside blocks :
blocks_names=rs.BlockNames(sort=False) blocks_count=rs.BlockCount() for i in range (0, blocks_count): objs_block_id=rs.BlockObjects(blocks_names[i]) objs_block_nb=len(objs_block_id) for j in range(0, objs_block_nb): rs.DimensionStyle(objs_block_id[j], "Default")This one doesn’t work and I don’t know why.
When I debug :
print objs_block_id[j]… display the GUID (it’s good)…
print rs.DimensionStyle(objs_block_id[j])… display the style (it’s good) but…
rs.DimensionStyle(objs_block_id[j], "Default")doesn’ modify the style (it’s not good!).
Thank you!

Hello, is there a way to do a macro and assign it to a single custom icon, doing the following?
Once I select a group of curves that forms a flat drawing for laser cutting, I need to run these commands all in once to automate the process:
- Copying the object name (for example “HL-3-15”).
- Export selected (here is the prompt for selecting the file type, where I pick DXF).
- Using the copied object name as a file name (should be “HL-3-15.dxf”).
Or, is there a way that in a future release Rhino will have an option to use the object name to export multiple objects depending on their object name? For example, if there are 287 selected objects with 4 different names, Rhino would save 4 new files where the 287 objects were sorted out and allocated depending on their unique object name.
Thanks,
Bobi

Hi,
Greetings!
I have a problem, I need to find a point in a particular distanceexample:
consider a curve which has points on it
Consider this point on the curve, lets call A
Suppose if i need to find all the points which are at a distance of 8mm to 11 mm, but along the curve like this
but though the point D satisfy the condition, I dont want to be my output,
My expected output would be a list [B,C]
This article would help to find length of points along curve: Get distance between 2 points on line
My input would be list of guids of all point and guid of point A, expected output to be guid of Point B and Point C
Requesting help from all on the forum
Thanks in advance.

Condition: If chr string is same in the dataframe. Then distance between all gene will be calculated. Chr1 is present in row Index 1,3,5 so three combination will be made:

Similarly chr2 is present in index 1 and 2. So the only combination will be LC1 LI6 18 (16~34).

Hi all,
I have several surfaces I have to split with curves within a grasshopper python component.
I think I have managed to split them and the result are breps. However, I need these breps inside the component to be surfaces/polysurfaces (I can’t output them and use a different component) but I don’t know how to convert them via script. Possibly due to my limited knowledge of Rhino Common.See image and script below, should describe better what I am trying to do. Any ideas?
Thanks you so much in advance
- surfaces contains all surfaces to be split (guids)
- cuttercurves contains all curves used to split the surfaces (guids)
cut_surfaces_breps = [ ]
for surface in surfaces:cutter_elements = [rs.coercecurve(curve) for curve in cuttercurves] brep = rs.coercebrep(surface) split_brep = brep.Faces[0].Split(cutter_elements, 0.01) cut_surfaces_breps.append(split_brep)
- how do I convert all cut_surfaces_breps to surfaces?
The image belows shows cute_surfaces_breps, but I need this to be as polysurfaces/surfaces within rhino

Hello,
I am trying to import a pointcloud with a .txt/pts format with x,y,z,r,b,g values using a python script. I am currently using “pc.Add” for each individual point, but I am finding this takes a lot of time for large files (~8 gb) and tends to crash. I am looking to optimize my script by using pc.AddRange instead to bunch and append the points. I am stuck with the formatting of pc.AddRange.
I have read this post:
I am still unfamiliar with how the points needs to formatted. Are they supposed to be in an array format, I.E., “[ x, y, z, r, b, g]”? Thanks for any help.

While if I type this command(totally same script) manually in Rhino, perfectly works.
