If you click this button after performing a manual extrusion, the same extrusion is performed on the current selection as a preview and the caddy opens with Extrusion Height set to the amount of the last manual extrusion.Ĭombines selected edges that fall within the threshold specified on the Extrude Settings Opens the Extrude Edges caddy, which lets you perform extrusion via interactive manipulation.Click Extrude again or right-click in the active viewport to end the operation. You can drag other edges in turn to extrude them while the Extrude button is active.With multiple edges selected, dragging on any one extrudes all selected edges equally.Drag vertically to specify the extent of the extrusion, and horizontally to set the size of the base.When over a selected edge, the mouse cursor changes to an Extrude cursor.As you increase the length of the extrusion, the base increases in size, to the extent of the vertices adjacent to the extruded edge's endpoints.įollowing are important aspects of edge extrusion: The extrusion has either three or four sides three if the edge was on a border, or four if it was shared by two polygons. When extruding a vertex or edge interactively in the viewport, you set the extrusion height by moving the mouse vertically and the base width by moving the mouse horizontally.Įxtruding an edge moves it along a normal and creates new polygons that form the sides of the extrusion, connecting the edge to the object. Finally, use Attach in the Editable Spline to combine the shapes into one. If you need to control this, select only those edges that will result in a single spline, and perform a Create Shape operation repeatedly to make the correct number of shapes. When the Create Shape function runs into a branching 'Y' in the edges, it makes an arbitrary decision as to which edge produces which spline. If the selected edges are not continuous, or if they branch, the resulting shape will consist of more than one spline. The Smooth option results in vertices using smooth values, while the Linear option results in linear splines with corner vertices. The resulting shape consists of one or more splines whose vertices are coincident with the vertices in the selected edges. Choose Smooth or Linear as the shape type.Enter a curve name or keep the default.
Make changes, as needed, on the Create Shape dialog that appears.On the Edit Edges rollout, click Create Shape From Selection.Select the edges you want to make into shapes.To create a shape from one or more edges: This simple demonstration shows how, when manually subdividing a polygon mesh for modeling and animation purposes, you can save a good deal of time by using the Cut and Turn tools in 3ds Max. In Turn mode, click a diagonal (dashed line) once to turn it.Įach diagonal has only two different available positions, given no changes in any other diagonals' or edges' positions.Ĭompare this with the Edit Triangulation tool, with which you must click two vertices to change a diagonal's position.
