Summary:Command descriptions of PanelingTools plug-in for Rhino 4.0

Panels are repeated patterns on surfaces, polysurfaces, or a grid of points. PanelingTools offers two ways to create panels. The first is to use an ordered paneling grid of points (ordered by row and column) and the second is by objects (NURBS surface or polysurface). Panels are added in the form of edges, faces borders, face patches, flat faces, and a mesh. All panels are serialized.

PanelingTools use some geometry concepts such as NURBS curves and surfaces, the U and V direction of a NURBS surface, trimmed vs untrimmed surfaces and polysurfaces. For a quick review, you can check the NURBS Surfaces wiki page.

**Paneling by ordered grid of points**

- Step one: Create an ordered grid of points

Points must be ordered in rows and columns. Each point location is marked in its object name (shows in the object properties).

*Syntax is: Name(intRow)(intColumn)*

While PanelingTools offers many commands to create the ordered grid, you can create your own, through scripting for example. All that is required is to name point-objects and use for paneling.

Another advantage of separating grid generation from paneling is that you can edit the grid before paneling. You can run commands like pull, project, or transform to edit the grid, then panel.

*Step two: Create panels*

Select an ordered point grid, a reference object (optional), pattern, and the kind of output you like to get. Custom paneling and quads is also possible.

**Paneling surfaces and polysurfaces directly**

These are tools to panel directly using a reference surface or polysurface.

It is also possible to combine grid generation commands with paneling by grid commands using macros. Here is an example where you can have a PanelByGridArray:

*ptGridArray *Pause *Pause *ptPanelGrid _Enter

PanelingTools toolbars offers two sets of scripted commands that combine grid generation with paneling. Toolbars are available to download.

Note that the PanelingTools drop-down menu shows only after PanelingTools is loaded (usually after calling one of the plug-in commands for the first time in a session).

Command options:

Group: Option to group resulting point grid NameOfGrid: Grid name

**ptGridPoints**

Input grid u and v directions, base point, and u and v spacing. Using input, a base grid is created. Input points are rounded to the closest grid intersection points. This is why the result might be fewer points then the input. (Multiple points can be rounded to same index.) For a random set of points, the higher the spacing the more successful it will be to panel these points as illustrated in the image below.

If align option is set to *Yes*, points will shift location slightly to align with the defined spacing.

U_Direction: Option to set first direction V_Spacing: Reference grid spacing in the second direction V_Direction: Option to set second direction Group: Option to group resulting point grid DeleteInput: Delete input points AlignPoints: Align resulting points grid with reference grid NameOfGrid: Grid name

**ptGridPointsOnSurface**

Use this command to order existing points on a surface by that surface's UV.

Algorithm:Using input tolerance, surface is scanned for points (with u-dir iso-curves with spacing = 2*tolerance). If at least one point is found on the scan curve, then a row is created and added to grid. If align option is set toYes, points will shift location to align with scan line.

Tolerance : Round points by this tolerance (reference spacing = 2* tolerane) Group: Option to group resulting point grid DeleteInput: Delete input points AlignPoints: Align resulting points grid with reference grid NameOfGrid: Grid name

**ptGridSurfaceUV**

**ptGridSurfaceDistance**

Select a surface, divide by direct (spatial) distances. This command uses an algorithm where points are calculated incrementally (every new point depends on previously created points). This is why it might not give complete coverage. Note that grid name follows surface name. The command lets you select a point on surface to use as base.

Command options:

U_Distance: Distance in first direction V_Distance: Distance in second direction Extend: Option to extend surface when calculating the grid (get better converge) Group: Option to group resulting point grid
