Modes
No 3D application can operate without modes. They determine which part of an object you want to modify. Let's take the select tool as an example. Every raw polygon object consists of points, edges and polygons. But how should Cheetah3D know what you want to select. Do you want to select points, edges, polygons or the entire object? You therefore have to choose the appropriate mode first. Choose point mode for selecting points, edge mode for selecting edges and so on. The current mode will be displayed in the toolbar.
Attention: Many tools only work in some modes. The tools which aren't available in the current mode will be disabled in the menu.
Point mode: Use this mode when you want to manipulate points of polygon objects or control points and tangents of spline objects.
Edge mode: Use this mode when you want to manipulate the edges of polygon objects.
Polygon mode: Use this mode when you want to manipulate the constituent polygons of polygon objects.
Object mode: Use this mode when you want to manipulate entire objects.
Pivot mode: Use this mode when you want to move the object coordinate system.
