Grid snap

Grid Snap on

Turns on grid snap
.

Ortho Snap every ___degrees

Turns on ortho
and sets the ortho angle
.

Planar mode on

Turns on planar mode
.

Object snaps

Disable object snaps

Temporarily suspends set object snaps
.

Project object snaps to CPlane

Projects object snaps to the construction plane
in the active viewport.

Snap to locked objects

Snaps work on locked objects
and on objects on locked layers.

Use apparent intersections

The Intersection
object snap does not need to find objects that intersect in 3-D space. The objects only need to appear to intersect in the active viewport.

Snap radius ___ pixels

Sets the object snap
activation area radius in pixels. When the cursor is within this distance to the point to snap to, the marker

jumps to the point to snap to.

Dynamic object snap display

Controls the appearance of the object snap label.

Note: Turning on cursor tooltips
turns off object snap labels automatically.

Black on white

Displays black lettering in a white box.

None

Turns off dynamic object snap display.

Construction planes

Specifies the behavior of construction planes
in the viewports.

Standard construction planes

The construction plane of each viewport is independent from all of the other constructions planes.

Universal construction planes

The behavior of the construction planes in the viewports is linked. They all share the same origin and are positioned normal to each other. Moving, rotating, or otherwise changing the construction plane in one viewport, changes the construction planes in the other viewports, so the 90-degree/right angle/normal orientation of the construction planes is maintained.

If a construction plane is defined in some view, the Front view for example, and Universal mode is enabled, then the construction plane that was defined will be the Front plane of the new universal plane.

  • Click an option.

Options

CPlane

Sets object dragging parallel to the construction plane.

World

Sets object dragging parallel to the world x-y plane.

View

Sets object dragging parallel to the view plane.

UVN

Snap

Toggles grid snap mode.

When Snap is on, the marker

“snaps” between grid snap points, whose distance apart is set by the SnapSize
command or by the Options dialog box, Modeling Aids
page.

Grid snap is overridden by object snaps
and coordinate input
, and partially overridden by angle
and distance
constraint.

Planar

Limits successive picked locations to the same construction plane elevation as the previous location.

Steps:

Planar mode aids in creating planar objects with commands that allow free picking. Successive points have the same construction plane elevation.

Example

  1. From the Curve menu, click Free-form, then click Control Points.

  2. Pick the first point in the lower part of the Top viewport.

  3. Move the cursor to the Front viewport and continue drawing.

  4. You will see that all the points you pick define a planar curve at the same elevation in the Front viewport. (Watch the Top and Right viewports). That elevation for the Front viewport was defined by the very first point you placed in the Top viewport. With Planar off, the subsequent points would be at elevation 0 in the Front viewport.

Notes

  • Each point picked in a viewport will have the same elevation from that viewport’s construction plane as the previous point, regardless of where the previous point was picked.

  • Planar mode can be overridden with elevator mode
    or object snaps
    .

Ortho

Restricts the movement of the cursor to multiples of a specified angle from the last point created.

Notes

  • The Ortho command, clicking Ortho in the status bar, and the F8 key, are all toggles. Holding the Shift key changes the mode while you hold the key down.

  • The SetOrtho
    command prompts for a setting with the options On, Off, and Toggle. This is useful for inclusion in a script for the ReadCommandFile
    command.

  • When Ortho is on, marker

    movement is restricted to points at multiples of a specified angle from the last point created. The default angle is 90 degrees.
