Just above the grid display in the lower left-hand corner of Modeler is the Information Display. Most of the time this gives you feedback on the position of your mouse. However, depending on what you are doing, it can also display a variety of other information.Below are a few examples of what might be displayed with various tools:
A grid of squares - cleverly known as the grid - is visible in any of the orthogonal views, as well as the Perspective view. The grid serves as a visual reference when you move items around, but it will never render in a final image. The grid lines are darker every tenth square for visual reference. The Origin is located at the center of the grid.
You can find the current size of the grid squares in the Grid Information field at the very lower-left corner of the screen. Set the Unit System, Default Unit, and other options pertaining to the Grid in the Display Options Window.
Many Modeler tools (i.e., Rotate, Size, Stretch, Twist, Taper1, Taper2, Vortex, Pole1, and Pole2) can use different centers. This Action Center is located at the bottom of Modeler’s Interface.
(default keyboard shortcut N)
The Numeric Panel is a multi-functional non-modal window. Its contents and abilities change depending on what tool is selected. When you create primitives, it lets you refine graphically set values. When you use modifying tools, it lets you change various settings that affect how the tool performs. The Numeric Panel is located at the bottom of Modeler’s Interface, or by just pressing the N key. It may be left open continuously.
Use the Actions pop-up menu to Reset the fields to their default settings or to Activate the tool. (You can also press the N key to activate the tool.) Activating a tool turns on its interactive handles, if any, in the viewports. This can be for primitive shape, influence range, and so on. It will also activate the numeric fields, if they are ghosted.
You can also reset to defaults by clicking a reset area when a tool is selected, but not activated.
(default keyboard shortcut Return)
The Drop Tool command (Located at the bottom of Modeler's Interface) will commit to the changes made with the currently selected tool and will deactivate the current tool.
(default keyboard shortcut Shift Y)
Working in Symmetry Mode (Symmetry button, located along bottom edge) works on selection, as well as on editing. This mode will allow you to work on one half of your object and Symmetry will perform all edits and selection on the opposite side of the geometry.
Operations on the positive side of the X axis also inversely affect the negative side of the X axis. When this mode is active, your object is theoretically split in half at X=0.Generally, you should perform all of your edits on the positive side of the X axis when using Symmetry. Using the negative side may lead to unpredictable results.
If you get unpredictable results, make sure the negative-side geometry is exactly the mirror of the positive-side geometry with X=0 as the center point. If the negative-side geometry is the slightest bit off, it will not be affected. Generally speaking, this mode was meant to be used where the geometry to the left and the one to the right of X=0 mirror each other. (However, all of the geometry does not need to be a mirror image, only the portion you want to work on symmetrically.)
The Fit Selected command (Shift A) respects symmetry. If both sides of an object are selected and Symmetry is active, then only one-half of the selection is used to compute the fit.
When you select polygons/points on the positive X axis and Symmetry Mode (Symmetry button) is active, polygons/points/edges on the negative X axis are also selected (or deselected).
Polygons/points/edges must be exactly opposite each other on the positive and negative sides of the X axis for this command to work properly.
Symmetrical Modeling: Many of the Modeling tools will work in Symmetry mode. Most of the Modify menu tools work fine. Others such as bevel or smooth shift also work. Some tools such as Bandsaw do not work in Symmetry mode. In such a case you may have to use the tool on one side then use the Mirror tool to make sure the changes are done on both sides of the X Axis.
(default keyboard shortcut Q)
The Change Surface command (Located at the Bottom of Modeler’s Interface) will bring up the Change Surface dialog to set the surface name and basic attributes for the selected polygons.
VMaps can be created using the buttons in the lower-right corner of Modeler. These are simply shortcuts to the same options that can be found in the Vertex Maps Panel (Windows> Vertex Maps Panel). Choose a Vmap Mode to work in by clicking on one of the Vmap Mode buttons (W, T, M, C, S). Select which Vmap to edit from the Vmap drop down menu located next to the Modes buttons.
See Vertex Maps Panel for more detail.
