Select by similiar material

This will select objects by user-specified materials.

Select by Surface Style Name

Displays a menu allowing user to select a surface style by name. The script then selects objectsng user to with the selected surface style.

Select Similar Normal

Selects faces by a given (selected) faces normal.

Convert Selection

Four commands that will take a point, segment or object or face and select the chosen entities that are attached. For example, if an object selection is converted points, the object is deselected and all its points are selected. These commands will appear as four separate options under one heading in the menu.

Select Similar

Command that will select other similar, visible objects based upon optional criteria. For example, one could select an object, then run this script to select all other objects within the same layer as the original object.

Reverse Selection

Command that will deselect all currently selected entities and select anything that was unselected and visible.

Count Selected Entities

This palette will display a count of all currently selected entities (points, segments, faces, and objects).




Separate faces by color

Separates an object into one or more objects based on the face-level colors. Deletes the original object.

Tool that allows user to align an object by picking 3 points at the current location and 3 points at the target location. 1

Batch sweep

Utility script to allow multiple sweep paths with single source shape. 1

Clean Line

Reduces the point density of selected lines. User specifies a tolerance. Groups of points that are within that tolerance are consolidated into one point. 1


This will divide objects along arbitry direction by scale command. 1

Door Builder

Builds a door to match the width of a selected line. 1


Moves objects vertically so the bottom meets the top of a terrain model. 1

Gravity 2.5

Terrain Doctor

A method of automatically analyzing and fixing terrain modeling. 1

Random Nurbs

Script sample file to show how to create a nurbz object with control points whose location changes randomly along the u direction of the surface. 1

Parametric Resolution

This tool-like palette allows you to change the display resolution or parametric objects instantly. 1



Object Attributes

Distribute based on materials

This will create a new layer for every surface style. It then moves objects to those layers based upon the object's assigned surface style.

Fix inverted Objects

Detects all solid objects in a project that have negative volume. If there are any, a dialog is posted, that gives the user the choice to : do nothing, pick the objects, and reverse the objects. 1

Name object by material

This will rename all selected objects so that the name matches the surface style assigned to the object. 1

Remove copy from Name

Command that will allow user to automatically remove "Copy" from the name of new copied objects as they are created. 1

Clear face color and Texture
