Hello guys,
I wanna refer crvs from layer by Horster Plug-ins and through that I got ID of the crvs.
However with the code “rs.coercecurve(ID)”, the ID cannot convert to curve as I needed.
There must be some piece of code that I missed so anyone know how to finish it?
Thanks so much!

Hello,
I’m currently using this snippit to get a texture mapping onto a surface:
private TextureMapping GetPlanarMapping(Brep brep) { var bbox = brep.GetBoundingBox(false); var mapping = TextureMapping.CreatePlaneMapping( Plane.WorldXY, new Interval(bbox.Min.X, bbox.Max.X), new Interval(bbox.Min.Y, bbox.Max.Y), new Interval(bbox.Min.Z, bbox.Max.Z)); return mapping; }It creates a Planar (UV) mapping that is mostly correct but slightly offset. If switched (in the UI) to UVW it maps correctly. How can I create this as UVW?

I am trying to find a way to escape python commands and this developer page looks like it should help: Canceling a Python script in Rhino but only the first two code snippets are python then the rest of the page is in VB?
The escape examples work as scripts BUT as commands they do not.
I am finding that in commands rs.sleep() does slow down the but does not give rhino a chance to listen to scriptcontext.escpae_test()
And in commands Rhino.RhinoApp.Wait() has no effect
Has anyone found a way to successful escape python commands in rhino 5?

Hi All,
I’m trying to implement this Intersection.MeshRay overload through GHPython (i.e. that return the “faces on mesh that ray intersects”). I think I’ve got it working, but just wanted to check that I’m going about it properly. Calling the overload through IronPython seems a wee bit convoluted this way:
import Rhino as rc from System import Array import clr def meshRayIntersect(mesh,point,vector): """ Intersect a mesh with a ray, including intersected mesh face IDs """ ray = rc.Geometry.Ray3d(point,vector) faceIDs = clr.StrongBox[Array[int]]() rayP = rc.Geometry.Intersect.Intersection.MeshRay(mesh,ray,faceIDs) if rayP: rayPt = ray.PointAt(rayP) faceIDs = list(faceIDs.Value) return rayPt,faceIDs else: return None XPt, XIDs = meshRayIntersect(MyMesh,MyPoint,MyVector)That is, having to instantiate an
Arrayinside aStrongBoxprior to callingrc.Geometry.Intersect.Intersection.MeshRayjust to return the faceIDs. I might be way off hereCheers,
Anders

Hi,
Maybe a dummy question, I didn’t find any similar thread: for a given quad
ON_MeshFace, are their four verticesviordered with a given criteria (clockwise or counter-clockwise)? How can I know it?Thx

Hi Mike,
I realise this topic is 2 years old, however, I’m having the exact same problem.
I’m trying to reconstruct a brep from data I extract from another brep.The situation:
I have a brep in a script (with trimmed faces) and I’m trying to export it to a JSON, which I can then read in another script to reconstruct it.
So I can get all the curves2d, curves3d, surfaces etc. But somehow I get an invalid brep when reconstructing. Exact same message as above. The preview in the rhino viewport shows the correct geometry by the way.Did you have any luck fixing the problem?

Is there some “bounding region” mechanism or clipping behavior inside CRhinoMeshObject that causes custom grips to be clipped? I’m seeing my lines and points randomly disappear when dragged far away from the “source” object. I’m assuming there’s some bounding region I need to update?
Rendering code for my grips below:

Hi all.
I am near final area of porting about 30 tools to a plugin, my problem is I want grasshopperesque controls, which are dead simple to create in winforms, and of course work fine in r5 and r6… but i want to be able to service mac platform too, meaning i have to go ETO,
I can find some code examples of how to do this, but its like going back to 1990 and hard coding the components in python TK. This means if i need to get back in there later its a nightmare to change code.
I tried using the eto VS snapin tool but cannot find its visual designer component that will allow me to manipulate sliders etc graphically.
Can anyone point me to a simple easy to understand tutorial on how to get ETO working similarly to just using visual studio forms designer?
Many Thanks!

Trying to capture multiple views in the most optimal way - is there any other option than RhinoView.CaptureToBitmap() ? I found this function quite slow (10 ms to capture one image), where the _testmaxspeed command runs here at >320 fps - effectively rendering the view in ~3ms. Thanks for any help in advance.

Hi,
Is there any rhinocommon method that call rhino6 command MeshFromPoints?
Or is it just that the same .rhp file and it will not be added as a method to call it throught .net?

The Rhino command allows to override public override void LoadProfile(string lpszSection, ref RMA.Rhino.MRhinoProfileContext pc).
I can not find anything similar in Rhino 6. I have found PersistantSettings, but I have no idea how to access them. Is there any example?

I’m trying to create a fillet between two curves on Rhino 5 SR14. It works like magic when I use the button and select the two curves but I cannot make it work from a Python script calling the _Fillet command. Attached, you will find the project containing the two curves and the script I’m using…

Now I know there are more high-level approaches to custom grips, but I prefer to keep this approach for now due to the versatility I may need in the future.
I’m implementing my custom grips and they are working fine, however when I drag a grip, then hit ctrl+z, while the mesh object resets correctly, the grips remain in the old wrong position. I expected these to reset and for CRhinoObjectGrips::NewObject() to be called (it isn’t).
What do I need to add here to make undo work as expected? I don’t (yet) use any custom data attached to the mesh or grips.

Have you a solution for use Python 3 ?
Or can i use Python+Pythonnet in replacement ?Really, I’m confused, I’m starting to learn Python and it’s everywhere recommended to use Python 3.
I see,and

Hi,
I have simple question regarding displaying object through rhino pugins / c++.
Is the only way to display object is by baking it? Like context.m_doc.AddSomeGeometryType()
If I have simple for loop and in each iteration I move point by one unit in z axis. Each iteration I would like to display.
Would I need to somehow get existing point object in rhino and bake each time? Do rhino commands always executes a function only once? Or there is a similar approach like grasshopper ExpireSolution(true) method?
Is there any example illustrating this?
The reason for asking just for iterative display purposes while method is running.

With single object everything worked ok so i assume bitwise operators are here ok:
go.AcceptNothing(false); go.DisablePreSelect(); go.GeometryFilter = Rhino.DocObjects.ObjectType.Surface | Rhino.DocObjects.ObjectType.Extrusion | Rhino.DocObjects.ObjectType.Brep | Rhino.DocObjects.ObjectType.Mesh | Rhino.DocObjects.ObjectType.InstanceDefinition | Rhino.DocObjects.ObjectType.InstanceReference; go.GroupSelect = true; go.Get();@Dale would you mind to look at this? I tried adding
go.GetMultiple(1,0)but nothing changed.

I’m writing a set of grasshopper components in Visual Studio 2017, and I have a collection of unit tests (set up with Tom Makin’s solution here) that have been working well.
Any time I try to run tests that involve Curve.Offset(), though, it throws my favorite error: “Object reference not set to an instance of an object.” I spent some time yesterday debugging the problem and am pretty sure it’s this specific method, and all of its versions.
For reference, I’m testing a slightly reformatted version of this older grasshopper component (which uses Curve.Offset() just fine). Lines 50 & 51 are the troublemakers in the new project’s tests.
This is my first time unit testing, and some searching brought up references to threading, which I’m not completely proficient in. Is this issue a limitation of certain RhinoCommon methods, or is it something I’m just approaching the wrong way?
