Use local instead of global axes
Move, scale, rotate, flip or place objects
Position multiple copies of an object along a curve
Position an object based
on input points/planes
Lets
you place an object on another object or in space, based on input
points (or existing construction planes) on both the source object
and the target location.
Transform > Object Placement > Place enables you to position
an object based on input points that describe either a single point,
an axis (2 points) or a plane of reference (3 points or an existing
construction plane) on both the source object and the target location.
NoteThe
target location can be on another object, or simply a position/orientation
in space.
If only one point is
selected on both the source and target, the source object is simply
translated so the two points coincide. If two points (an axis) are
specified on each, the transformation applied to the source object
consists of both a translation and a rotation so the two axes match.
If three points (a plane)
are specified, the tool calculates the appropriate transformation
and translate/rotate the selected geometry (source object) to the
established target position so that the two oriented planes coincide.
The source object is placed according to the location and order
of the points picked on the target location.
To transform the object:
- Choose Transform > Object Placement > Place
- Select the object you want to position
(source object).
- Click down to specify up to three points
on the source object (or select existing points) or select an existing
construction plane.
After
positioning the first point, a point locator is displayed. After
positioning the second point, avector between the two points is
displayed. After positioning the third point, a plane is displayed.
NoteIf
you click on an object, the point is constrained to that object.
If more than one object are under the cursor, the pick chooser appears.
Point to the hand icon next to the object you want. Keep the mouse
button down to position the point.
TipUse
or
snap to help position the
points by attaching them to a CV, edit point, or curve. Use
snap to snap a point to
a grid intersection or detach an existing point (created through
the use of the tool) from the geometry.
- Click the Accept FROM button.
- Click down to specify three points on
the target location (or select existing points) or select an existing
construction plane.
- Click the Accept TO button.
NoteAfter
the two sets of points are selected, Edit From and Edit
To buttons appear, allowing you to interactively modify
any of the points on the source (Edit From) or target (Edit To) location.
These buttons remain on the screen after executing the Place operation.
NoteIf
the from points are attached to the source geometry, this feature allows
you to adjust the placement in an iterative fashion.
- Click the Place button
in the lower right corner of the screen.
The object is moved and rotated so that the
planes defined by the two sets of points you selected in steps 3
and 5 coincide.
- Make any required modification to the
point positions using the Edit From and Edit
To buttons, then click the Place button
to re-position.
NoteThe transformation can be undone by choosing
Edit > Undo . This causes the geometry
to return to its original position, but maintains the point selections
on the source and target locations.
- Choose another continuous tool to exit
the Place tool.
The points are deleted
by default. To keep the points around, turn off the Delete
points when finished option in the option box prior to
exiting the tool.
If the points were not
deleted, you have the option of re-entering the Place tool
and selecting/modifying the existing points at a later time.
To modify the position
of the points (at a later time):
NoteThis
is only possible if the Delete points when finished option
was turned off when the Place operation was first executed.
- Choose Transform > Object Placement > Place .
- Select the source object.
- Select one of the original "from" points
on the source object.
The
labels on the 3 "from" points (FromOrigin, FromVector, FromPlane) become
visible.
- Modify one or more "from" points by moving
them.
- Click the Accept FROM button
- Select one of the original "to" points
on the target location.
The
labels on the 3 "to" points (ToOrigin, ToVector, ToPlane) become
visible.
- Modify one or more "to" points by moving
them.
- Click the Accept TO button.
Edit
From, Edit To and Place buttons
appear.
- Click the Edit From or Edit To button.
- Make additional modifications to the
"from" and/or “to” points.
- Click the Accept FROM or Accept
TO button.
- Click the Place button.
The new transformation
is calculated and the object is moved and rotated so that the planes
defined by the new point locations match.
- Repeat steps 9 to 12 as necessary to
incrementally adjust the placement of the object.
- Choose Pick > Nothing to start over and place
another object, or choose another continuous tool to exit.
