3ds max extrude Command Designtech
Lets you perform manual extrusion via direct manipulation in the viewport. Click this button, and then drag vertically on any polygon to extrude it.
Extruding polygons moves them along a normal and creates new polygons that form the sides of the extrusion, connecting the selection to the object.
Following are important aspects of polygon extrusion:
When over a selected polygon, the mouse cursor changes to an Extrude cursor.
Drag vertically to specify the extent of the extrusion, and horizontally to set the size of the base.
With multiple polygons selected, dragging on any one extrudes all selected polygons equally.
You can drag other polygons in turn to extrude them while the Extrude button is active. Click Extrude again or right-click in the active viewport to end the operation
