Mesh Menu

General

The Mesh menu has various tools that allow you to adjust the structure of polygon objects and spline objects. Most of these tools are available in the point, edge and polygon modes.

Any objects that you want to use with these tools must be editable. You can make objects editable by selecting them and choosing Mesh / Conversions.

Usually, the Structure tools affect the selected points, edges or polygons only. However, if none of these elements are selected, then most of the tools will affect the entire selected object(s). Hidden elements will usually be ignored. Some tools such as Knife, Bevel, etc. can be used to "grab" an element (e.g., an edge) directly with no prior selection.

Any structure tools that cannot be used in the current editing mode (point, edge or polygon) will be grayed out. For example, Edge Cut only works with edges and therefore will be grayed out in point mode and in polygon mode.

You can also use the structure tools with multiple selected objects. For example, you could create two cubes, make them editable, select a polygon on each cube and extrude both polygons at the same time using the Extrude tool.

Tip:
For all tools whose affect on hidden elements can be disabled (e.g., the Knife tool), the Customize Commands Manager offers the Toggle Visible Only command. Assign a hotkey for this command to easily switch between modes.

When using an interactive tool the most recently completed action can be undone by pressing the Esc key on your keyboard as long as the mouse button is still pressed.

Modeling modes

The workflow for using the structure tools differs depending on whether you are working in the default modeling mode (Tools / Default Mode) or in the tweak modeling mode (Tools / Tweak Mode).

Tip:
Note also the Sculpt Brush, which can be used to affect normal polygon meshes (without special Sculpt subdivision).

Working with hotkeys when modeling

A typical workflow is, for example, as follows:

Select several polygons, edit them using the Extrude tool, switch back to the Select tool and select the next set of polygons to edit.

This can be done in one of two ways using hotkeys:

You can use most of the structure tools interactively. Also, many of the tools have settings that you can adjust in the Attribute Manager. For as long as the tool is active, you can change any of its parameters or options and you will see the changes applied in real-time.

Mesh Menu

You can quickly access various commands for points, edges and polygons from the context menu. Different commands are available depending on whether you are working in point, edge or polygon mode These commands are mostly from the Mesh menu.

Command Options

Several commands (mostly in the Mesh menu) have multiple options. It can be irritating if these are displayed every time a given command is called up. This is why the icon as highlighted in the image above is available. When clicked upon, the command options will be displayed and can be defined accordingly. These settings will then apply EVERY time the command is called up.

The Customize Command Manager contains an option that lets you define the previous method (options will be displayed each time a command is called up) or the new method should be applied when a command is called up (via hotkey only).

RELEASE 22

In general there are several minor new modeling features that are not in the form of new features but are improvements in performance. For example:

  • The Select Connected command now also works in conjunction with the FFD object.
  • Minor improvements such as faster Use Edge and Point mode, generating more precise geometry for n-gons, etc.
  • Spin Edge is faster and behaves more consistently in conjunction with n-gons.
  • The Collapse command now interpolates UV coordinates better.
  • Bevel works faster and can handle things such as UV coordinates and the interpolation of vertex colors much better (the same applies to the Bevel Deformer).
  • Slide now works better in conjunction with coherent branching selections.
  • Iron can now handle n-gons better.
  • Stitch and Sew works faster and can also handl n-gons better.
  • Move now also works with soft selections and the Along Normals option.
  • TheExtrude function now works much better with regard to angles.

Tip:
Several of the tools described in this section can also be found in the main menu under Splines. This is because they work for both object types. However, they are only described here.
