POLYGON EDITING, Extruding Edges

Edges can be extruded to create new polygons. Edges are extruded with different behaviors depending on whether they are ‘internal’ or ‘external’ (inside the mesh, or on the perimeter boundary). The constraint methods are the same as with extruding polygons, so only issues specific to edge extrusions are shown below.
Tools are organized into tool groups. Each tool within the group can have its own key, but can also be cycled to to become the active tool via a ‘tool group’ key. By default, the U key cycles the tool group, but also activates the current tool within the group when another tool is currently active. This allows for flexibility in switching tools.

POLYGON EDITING, Extruding Polygons

The Extrude Tool Group consists of the Extrude Element Tool, the Extrude Normal Tool, and Extrude Inset Tool. Polygons can be extruded to extend existing geometry. Polygons, edges and vertices (sometimes referred to as points) can be extruded. Extrusion can be constrained with the methods listed at right.
Tools are organized into tool groups. Each tool within the group can have its own key, but can also be cycled to to become the active tool via a ‘tool group’ key. By default, the U key cycles the tool group, but also activates the current tool within the group when another tool is currently active. This allows for flexibility in switching tools.

POLYGON MODELING, Scale Tool Group

The Scale Tool Group consists of the Scale Element Tool, and the Scale Normal Tool. Scaling polygons happens uniformly by default, using the selection center as scaling center. However, scaling can also take place along a standard axis, relative to a selection normal or along a custom grid or guide. Scaling polygons, vertices and edges generally produces the same results.
Rotation for any element (polygon, edge, vertex) is;
1. Free-form, Uniform
2. Perpendicular to Grid
3. Standard axis (X, Y, Z)
4. Custom Axis/Guide
5. Selection normal
6. Scaling Single Edges
Tools are organized into tool groups. Each tool within the group can have its own key, but can also be cycled to to become the active tool via a ‘tool group’ key. By default, the K key cycles the tool group, but also activates the current tool within the group when another tool is currently active. This allows for flexibility in switching tools.

POLYGON MODELING, Rotate Tool Group

The Rotate Tool Group consists of the Rotate Element Tool, and the Rotate Normal Tool. Rotation of geometry inside the polygon modeler is grid relative. By default rotation takes place around a line perpendicular to the active grid. However, rotation can also take place around a standard axis, selection normal or a custom grid or guide.
Tools are organized into tool groups. Each tool within the group can have its own key, but can also be cycled to to become the active tool via a ‘tool group’ key. By default, the J key cycles the tool group, but also activates the current tool within the group when another tool is currently active. This allows for flexibility in switching tools.

POLYGON MODELING, Move Tool Group

The Move Tool Group consists of the Move Element Tool, the Move Normal Tool, and the Slide Element tool (edge mode only). Design 3D controls the movement of elements using differnet 'constraint' modes. These are active grids, guides, geometry 'normals' and sliding. The listing below shows how the 3 tools in the Move Tool Group operate relative to these constraints in order to precisely manipulate geometry.
Movement for any element (polygon, edge, vertex) is;
1. free form, parallel to the active grid (default behavior)
2. along a standard axis;
3. perpendicular to the active grid;
4. along a custom guide/axis;
5. geometric ‘normal’ relative;
6. slide (edge mode only);
Tools are organized into tool groups. Each tool within the tool group can have its own key, but can also be cycled to to become the active tool via a ‘tool group’ key. By default, the M key cycles the tool group, but also activates the current tool within the group when another tool is currently active. This includes Slide, even though its direct key is Shift+S. This allows for flexibility in switching tools.

Moving the pivot to a specific mesh location

This tutorial shows how to move a polygon mesh's pivot a location based on an elements position (vertex, edge, face). This can be very useful for rotating an object around a specific mesh location.
