MAYA Tutorial - Polygonal Modeling

Polygonal Text Settings

When you create polygonal text, Maya provides option that you can set to display and create your text for subsequent polygonal-type editing.


Three sided polygons are created. This is the default.

Tessellation Methods

Standard fit

This is the default tessellation method. It is adaptive tessellation, meaning that following option is used to determine when to stop the tessellation. The tessellation stops at the fractional tolerance value you set. If there is an edge shorter than the Minimal Edge Length, the tessellation stops on that edge. If the surface is flat enough with in the edge, the tessellation stops here.


Set the tessellation method to General to display the following options. Unless Use chord height or use chord height ratio is turned on, a uniform tessellation is performed. Each span is split into a number of polygons depending on the number U and V values you set.


Set the tessellation method to Count to display the Following slider. Count slider is used to determine how many polygons the surface can be tessellated into.

Control points

This tessellation method converts the Nurbs model to polygons while matching the CVs of the original Nurbs surface. There are no other options for this operation.


You can pull faces and edges out from polygonal objects using the Extrude Face and Extrude Edge commands.

Extruding Faces

You can extrude faces either interactively or directly through the option window. Select Edit Polygons > Extrude Face ,set whatever option you need and click the Extrude Face button.

  • If you want to extrude all the faces of an object, marquee-select the whole object to highlight the faces.
  • If you want to extrude certain areas  of an object, shift-or Ctrl-click to select those face only.
  • If you want to extrude ,duplicate or extract multiple faces together, turn on polygons > Tool options >Keep Faces Together. 


you are not happy with results, select Undo from the Edit menu, change the  Extrusions settings in the channel Box or Attribute Editor and press Enter.

Extruding Edges

You can extrude edges either interactively or directly through the option window. If you prefer to set the options first and then extrude the edges, Select Edit Polygons > Extrude Face.

Duplicating Faces

You can duplicate and transform faces interactively or directly through the option window.  Select the faces of the object you want to duplicate. Press the right mouse button and select Face or press F11.

  • If you want to duplicate all the faces of an object, marquee-select the whole object to highlight the faces.
  • If you want to duplicate certain areas  of an object, click to select those face only.

You can also Duplicate Faces through Edit Polygons > Duplicate Face.

Extracting Faces

While Extracting ,Maya disconnects the selected Faces from the original shape, by duplicating the appropriate edges and vertices. The extracted faces become their own shell with in the object. This is the another way to make holes in the object while retaining their original faces.

Seperating the extracted faces creates distinct polygons out of the faces and the original object.

To extract Faces

  • Select the face of the object you want to extract. Press the right mouse button and select Face from the marking menu or press F11,then shift or Ctrl-Click to select the faces.
  • Select edit Polygons > Extract. The selected Faces are extracted.

Smoothing Polygons

There are three ways to smooth polygons.

  • Using Polygons > smooth.
  • Using Polygons >Average vertices.
  • Using the smooth operation of the sculpt polygons Tool to average the values of painted vertices to produce a smoother surface.

Polygon Selection

With Edit Polygons > Selection menu, you can constrain the selection of components to a specified area of a polygonal model and perform operations on those components in that specified area only without disturbing the rest of the model.

Select Edit Polygon > Selection >Grow Selection Region to increase the number of components you initially selected.

Selecting Boundaries

You use Edit Polygons >Selection >Select Selection Boundary to define the boundary of the current selection region. It is a quick way to select the boundaries of whatever is currently selected.

Selection a band of edges

Use Edit Polygons > Selection > Select Contiguous Edges to select a contiguous band of edges around model. With this you can select one edge, choose select Contiguous Edges, and it will select the rest of the edges  in the center automatically.

Max 2d Angle ,Max 3d Angle

These settings determine how far the selection continues based on the angles between edges. The 2d angle refers to angle made by the surface topology, regardless of the surface's shape. The 3d angle refers to angles made by the surface's shape, as measured in world or local space.
