PanelingTools Commands

Summary: Commands description of PanelingTools Plugin for Rhino4.0.


Contents

BACKGROUND


Panels are repeated patterns on surfaces, polysurfaces or a grid of points. PanelingTools offer 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 NurbsSurfaces 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, users can create their 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 users can edit the grid before paneling. They 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

COMMAND DESCRIPTIONS



Toolbars

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



Menu

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

This is for those who have all curves in both directions and would like to make a grid out of curves intersections.

Command prompts to select curves in each of the two directions to make the grid. Selection order defines order of rows and columns in the grid.

Command Options:

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



Back to top

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 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.

Command Options:

 U_Spacing: Reference grid spacing in the first direction.
 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



Back to top

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 to “Yes”, points will shift location to align with scan line.

Command Options:

 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



Back to top
