ononSmartView

Experimental Rhino 8 viewport navigation plug-in · 繁體中文版

ononSmartView is a C# / RhinoCommon plug-in for focusing on Brep faces, aligning the camera to Rhino's active construction plane, and navigating with a lightweight ViewCube. It targets .NET 8 and AnyCPU and does not use WPF or Windows Forms.

TEST VERSION — incomplete and subject to change. This plug-in still has known gaps and unverified behavior. It has been tested on macOS with Rhino 8.35; the Windows Yak package has been built but not tested in Windows Rhino. Do not rely on it for production work, and save backups of important models.

Features

• Select a Brep face to set the construction plane and animate the camera to a face-on parallel view. Planar faces are preferred; curved faces use a tangent frame at the picked point.
• ononSmartViewBack restores the camera, projection, target, lens, and construction plane captured before focus. ononSmartViewFlip turns the focused view around.
• The ViewCube supports face, edge, and corner snaps, drag rotation, quarter-turn buttons, and reset. In Perspective, reset returns to the view recorded immediately before the current ViewCube session. Standard views return to their default direction and frame the model.
• The circular C button toggles automatic camera alignment to the active construction plane. It only changes the setting; it does not move the camera when clicked. When enabled, the camera follows the next construction-plane change, including Object and World CPlanes. Perspective remains perspective for gumball operations. The plug-in does not change Rhino's Auto CPlane preference.

Commands

Command	Description
ononSmartView	Select a Brep face and focus it.
ononSmartViewBack	Restore the camera and construction plane from before focus.
ononSmartViewFlip	Flip the focused view.
ononSmartViewCube	Toggle the ViewCube.
ononSmartViewAutoFace	Toggle camera alignment to the active construction plane; same as the circular C button.
ononSmartViewFocusFace	Scriptable face-focus command; prompts for Brep GUID, face index, and viewport name.

Install on macOS

1. Download ononSmartView.macrhi.
2. Open the .macrhi installer with Rhino 8 and restart Rhino if prompted.
3. Remove any older SmartView plug-in first to avoid duplicate ViewCubes or Auto CPlane listeners.

The installer is unsigned, so macOS security settings may ask you to confirm loading it.

Install on Windows

The Windows package targets AnyCPU and .NET 8. Download ononsmartview-0.1.0-beta-rh8_35-win.yak, then install it with Rhino 8's Yak command-line tool:

& "$env:ProgramFiles\Rhino 8\System\yak.exe" install "C:\path\to\ononsmartview-0.1.0-beta-rh8_35-win.yak"

Restart Rhino after installation. This package is built for Rhino 8.35 and later on Windows. If Yak installation is unavailable, download the manual-load archive, extract both files into one folder, then install/load ononSmartView.rhp with Rhino's PlugInManager command.

Build

Requirements: Rhino 8 with RhinoCommon and the .NET 8 SDK.

dotnet build ononSmartView.csproj -c Release

On Windows, use Rhino 8's System/RhinoCommon.dll reference. scripts/build-windows.ps1 builds the plug-in and creates the Rhino 8 Windows .yak package and manual-load archive.

Testing and limitations

The smoke-test script creates a box and a slanted face for manual checks; it does not automate face picking or camera assertions. Rhino MCP testing on macOS Rhino 8.35 verified the C toggle with the legacy plug-in disabled. Windows runtime behavior and the latest face-axis alignment still need in-Rhino verification. Treat this release as a test build: some details may be incomplete, inaccurate, or change as issues are found.
