Hi,

I’m trying to export to STEP in RhinoCommon. I can only find this class which is only available in Rhino 7 Windows: https://developer.rhino3d.com/wip/api/RhinoCommon/html/T_Rhino_FileIO_FileStp.htm

What’s the recommended way of doing it in Rhino 6, or on Mac?

Thanks!

Best,

hi everyone. In material there have three Custom Settings’ tool : specular、reflection and transparency I want to control specular use c++ code.(Red circle in picture which is named " Gl ")

I can use m_transparency& m_reflectivity in “opennurbs_material.h” to control it’s proportion and both work.Also I can change specular’s color but can’t control specular’s proportion with m_shine or SetShine(). It’s there have any code can do it ?

I need that the maximum length of the segments does not exceed 0.2, for some reason this is not happening, any idea?

Hi!
In the SDK there is a call

void DrawMeshVertices(const ON_Mesh&, const ON_Color& color);

So I tried to use it in my conduit, but nothing visible appeared on the screen. Is there anything more (e.g. vertex atributes) that I have to set up?

What I tried instead was something like this:

int iVertexCount = mesh.m_V.Count();
ON_3fPoint P;
for (int i = 0; i < iVertexCount; i++)
{
P = mesh.m_V[i];
pipeline.DrawPoint(P, 1, RPS_CIRCLE, color);
}

This works, but I would assume there maybe a more efficient way inside DrawMeshVertices(). The mesh uses ON_3fPoint for the vertex array, DrawPoint() uses ON_3DPoint…

Hi All,

I have created a customized ObjectPropertiesPage and its PageControl will be updated (via overriding UpdatePage()) when selected object changes.

Here is a problem it is kind of randomly occurring: it seems the panel is not rendered/refreshed correctly sometime. It will show up correctly until the cursor moves above or re-select the rhino object.

Do you have solutions to fix this?

Thanks in advance,

Hi,

We have a skin where we remove most of the Rhino UI and then create an instance of CRhinoTabbedDockBarDialog. We do it like in @dale’s SampleTabbedDockBar.

The problem is that the first time we call this window it’s floating on the screen:

01floating1920×1159 40.3 KB

We need to have it docked on the side from the beginning, like this:

02docked1917×1159 38.2 KB

How to achieve this? Maybe there’s a way through CRhinoUiDockBar, how exactly?

Hi,

I’m trying to use simple function OnEscapeKeyDown() in my C++ plugin for Rhino6 and I’m getting unresolved external symbol error on it. Here’s the line of code which produces it:
if (RhinoApp().OnEscapeKeyDown()) return nothing;

The line is within myClass::RunCommand(…){…} and myClass is derived from CRhinoScriptCommand.

At the same time, I see that another function works fine (no compiler/linker errors):
RhinoApp().RunScript(context.m_doc.RuntimeSerialNumber(),…)

Both functions are defined in rhinoSdkApp.h in CRhinoApp class and both are public.

I’m using Visual Studio toolset v141 and Rhino C++ SDK v.6.23.20055.13111

Can anyone give me advice on this? Is there some dll missing in this SDK as some other functions also produce linking errors?

Thanks in advance!

Hi,

I have a question about CRhinoApp::RunScript. It returns bool, but there not clear what it is (there’s no description in the comments to the function).

What I actually need is to run another C++ plugin with some parameters specified and somehow figure out if plugin execution failed or not. If it fails, RunCommand of that plugin returns CRhinoCommand::failure but I don’t know if I can somehow catch it with CRhinoApp::RunScript.

I would use CRhinoApp::ExecuteCommand but I believe I don’t have access to setting the parameters for the static object of that plugin class. Or is there a way to set parameters (how would I get the static object which is declared in the plugin main cpp)? I was looking to the description of CRhinoApp::ExecuteCommand…

Thanks!

Hi,

I have noticed a difference in behaviors between windows and macOS version of Rhino when selecting/unselecting objects in a document.

On windows, the process is rather fast.
On macOS it is much slower because Rhino open and prompt either Object properties or Display panel.

My purpose is to make possible to see an animation of a model being constructed (see the two gif under).

process-windows1191×743 978 KB

As you can see, there is a way to hide the panels under macOS, but I achieved this only manually. I tried to do the following :

Panels.ClosePanel(PanelIds.ObjectProperties);
Panels.ClosePanel(PanelIds.Display);

And reopen at the end of the process. But selecting the element will re-open the panels every time. Though it is only doing it on Rhino for mac.

The code i use for selecting objects is : doc.Objects.Select()
