Hi all,

within a plugin I was trying to explode linked block to use its components.
It all works fine with single standard blocks. But nested linked problems causes some problems.

As an example:
file A and file B are inserted in file C as linked blocks.
When using C as linked block in file D and exploding this block the result is obviously having linked blocks A and B in D. Unfortunately there is always ONE of these resulting blocks that is document controlled and can not be moved, deleted or edited in whatever way. It stays there where it is. Only by closing and opening the file this block will gone…

Code snippet (within a command):

ObjRef objRef = RS.RNGet.GetObject(“get block”, ObjectType.InstanceReference);
ObjRef[] objRefs;
Rhino.Input.Custom.GetObject go;
go = new Rhino.Input.Custom.GetObject();
go.SetCommandPrompt(“get instance object”);
go.GeometryFilter = ObjectType.InstanceReference;
go.SubObjectSelect = false;
go.AcceptNothing(true);
//go.GetMultiple(1,0);

        go.Get();
        if (go.CommandResult() != Rhino.Commands.Result.Success)
            return Result.Cancel;

        objRef = go.Object(0);
        if (objRef == null)
        {
            return Result.Cancel;
        }

        InstanceObject instObj = objRef.Object() as InstanceObject ;
        if(instObj==null)
        {
            return Result.Cancel;
        }


        RhinoObject[] explodedObjects;
        ObjectAttributes[] attributesOfExplodedObjects;
        Transform[] transformOfExplodedObjects;

        instObj.Explode(false, out explodedObjects, out attributesOfExplodedObjects, out transformOfExplodedObjects);

        Guid[] IDs = new Guid[explodedObjects.Length];
        for (int i = 0; i < explodedObjects.Length; i++)
        {
            Guid addedObjectID;
            if (explodedObjects[i].ObjectType != ObjectType.InstanceReference)
            {
                addedObjectID = doc.Objects.Add(explodedObjects[i].Geometry, explodedObjects[i].Attributes);
            }

            else
            {
                addedObjectID = doc.Objects.AddInstanceObject(((InstanceObject)explodedObjects[i]).InstanceDefinition.Index, ((InstanceObject)explodedObjects[i]).InstanceXform);
            }
            var addedObject = doc.Objects.Find(addedObjectID);


            addedObject.Geometry.Transform(transformOfExplodedObjects[i]);
            addedObject.CommitChanges();

I can provide the files as well…

Say I have a polysurface I intend to be water tight, but it has some naked edges I can see via “ShowEdges”.

Manually, I’m able to choose adjacent pairs with “JoinEdges” and, after doing this for a few edges, it’s sealed up.

I’m wondering how I can do this programatically with rhinocommon for a given polysurface with naked edges.

Any suggestions?

Thanks,

Hi,

In Rhino Plugin C++ I just want to retrieve two curves by separate commands.

I simply write the code below, but when I run it only first curve is selected but not a second command is not executed (neither I can select second curve nor I see the text “Select second curve”).
What I am missing?
In command line I see only Select first curve and no text Select second curve

What I write below as code is not right…

	CRhinoGetObject gc0;
	gc0.SetCommandPrompt(L"Select first curve");
	gc0.SetGeometryFilter(CRhinoGetObject::closed_curve);
	gc0.GetObjects(1, 1);
	if (gc0.CommandResult() != success)
		return gc0.CommandResult();
	const CRhinoObjRef& obj_ref0 = gc0.Object(0);
	const ON_Curve* crv0 = obj_ref0.Curve();
	if (crv0 == 0)
		return failure;

	CRhinoGetObject gc1;
	gc1.SetCommandPrompt(L"Select second curve");
	gc1.SetGeometryFilter(CRhinoGetObject::closed_curve);
	gc1.GetObjects(1, 1);
	if (gc1.CommandResult() != success)
		return gc1.CommandResult();
	const CRhinoObjRef& obj_ref1 = gc1.Object(0);
	const ON_Curve* crv1 = obj_ref1.Curve();
	if (crv1 == 0)
		return failure;

More simply can someone give an example how to retrieve two curves in separate commands?

Hi,

I’m puzzled by the tolerance setting for Curve.IsArc()

A curve that test True for Curve.IsArc() but False for Curve.IsArc(0.1)
I would expect any tolerance to return True if a zero tolerance is True
Do I lack some fundamental knowledge on what this tolerance means or is this buggy behaviour?

find the curve in this file:
ToArc_or_not_ToArc.3dm (22.3 KB)

import rhinoscriptsyntax as rs
import scriptcontext as sc

def find_arc():
    
    objs = rs.NormalObjects()
    
    for id in rs.NormalObjects():
        curve = rs.coercecurve(id)
        if curve:
            
            print 'arc at tol:zero == {}'.format(curve.IsArc()   )
            print 'arc at tol:0.1 == {}' .format(curve.IsArc(0.1))

find_arc()

printout:
arc at tol:zero == True
arc at tol:0.1 == False

We are working with some large point clouds and have had great success in using RTrees for rapid traversal and analysis. However, there is a obviously a large expense in the initial generation of the RTree, and if we could do it once for each cloud, it would save a lot of time. Does anyone have any recommendations for serializing RTrees for future use?

Is there a way to nuke all the keys all at once on a specific GUID using Python?
I know you can do it one at a time, but I don’t want to have to specify every key manually. I want to just feed the object ID into it and have a clean slate coming out.

Thanks in advance!

Hi,

I have a brep with just one surface that is trimmed. I would like to update the brep such that the surface’s x and y directions are inverted and swapped while still maintaining the trims. I’ve tried to figure it out myself but run into various road blocks, like the trims of a brep be readonly etc. I’m hoping someone could provide me some code to update a brep this way (using rhinocommon).

I have a group with 3 polysurfaces objects and 1 text dot.
I have let’s say like 20 groups that are like that.
After make2D runs the initial grouping gets lost, best it can do it give you 3 groups with “1” object in each, it will no longer have all 4 objects grouped up as previously?
Is there any workaround where I can still retain the original grouping?

Maybe there is a way to run make2d inside of python with extra functionality?
I need it working on windows rhino6.

Hi all.
I’m starting to write a plugin again with RhinoCommon and C#. Last time I did it with Rhino 4.
I am finding many improvements.

A silly question perhaps.
I haven’t found specific examples on how to set the plugin info.
Those that show Rhinoceros in the plugin properties dialog.
In version 4 there was a PlugInVersion() method, in 5 and 6 it seems to be a readonly property…

@dale would you mind give me a hint why this is happening? I made a simple set without and with (extern “C”) i don’t understand why i cannot use ‘normal’ ones.

For being precise i’m calling the library from the code.

I can not find the logic, it seems very complicated, maybe it’s just the initial impression.

The question is, Is there an easy-to-understand manual?

Maybe my problem has been to start with python.

Let me preface this by saying that I am an absolute novice with C#.

I’m trying to make a command that, no matter what the starting viewport, will run a “meshoutline” command from the top view, and upon completing the outline, return the user to the active view that they started with, leaving all viewports intact (i.e. creating a named view of the original view and switching to that view after the ‘outline’ didn’t work because it took the place of the top view, rather than changing the active viewport.)

The reason I’m trying to do this in C# rather than a simple macro or rhinoscript is that this command will be one of a growing library of custom tools in my office for which we need a degree of version control that we haven’t figured out a system for with macros or rhinoscripts (will be making a post about that question soon)

Any ideas?
