Images formats used for texturing and view-background images

Fast real-time OpenGL graphics views (2D and 3D) with whiteboard controls for easy navigation
Multipoint polygon and line editing down to vertex level
No polygon limits
Edit at different granularity - groups, objects, surfaces, vertices
Simple and easy manipulation of selected components
Powerful mouse selection with add/remove, select through and select closest components
Surface and vertex loop selection
Fast subdivision-surfaces with instant switch to view/hide subdivisions
Extrusion and surface revolution of lines and surfaces
Built-in fast OpenGL 3D renderer with adjustable field-of-view - instantly see results of your actions in 3D. Spin the model or switch into 'walk mode' for Quake-style control.
Realtime mirror for symmetrical work
Six boolean operations: Subtract, Intersect, Union, Cut-Away, Knife, Kife and Cut-away
Manipulate one or more vertices
- snap together
- snap to grid
- smooth shape
- align to axis
- create new surfaces from
- create a 2D mesh using
Manipulate one or more surfaces/polygons

Object crease angle support - smooth shapes with sharp edges without the hard work
Texture mapping support with switchable real-time rendering.
Switch a view into 'Inspect' mode to instantly see the 'clean' image
Anti-alias 3D views for smoother images
Snapshot images into the system clipboard for pasting into other software (Windows, Mac)
Create new surfaces/objects around any selection (Convex hull)
Objects can be named and searched for within a scene
Attach URLs to objects for use in VRML files
Attach string data to objects can be used as special directives for POV or renderman, or custom software
Navigate/Zoom around the 2D views with cursor keys and other single key presses
Hierarchical view window with drag/drop and locking/ hiding controls
Hide/unhide objects for easier/faster editing of complicated scenes
Headlight and up to 7 other positionable lights
24-bit colour palette with adjustable diffuse; ambient; emissive; specular; shininess and transparency
Adjustable 2D and 3D grid guide lines with grid-snap function
Distances, positions and sizes of selected objects displayed on screen
Scale a selection to a specific size
Configurable to use external renderers such as Povray ( Tools->Render )
Flip a selection about X, Y or Z axis
Remove duplicate vertices and surfaces ('optimize')
3D mouse (3Dconnexion) support e.g. SpaceNavigator
Multi-platform program - Windows, Linux and Mac OS X
Fast and memory efficient, compact program binary.
Software development kit and plugin interface.
