Using 3D Sketching Capabilities
Constraints in 3D Sketching
When sketching in 3D, you can snap to the
major directions, X, Y, or Z, and constraints are applied Along
X, Along Y, and Along
Z, respectively. These are constraints to the global coordinate
system.
When sketching on a plane, you can snap to
the horizontal or vertical directions in the plane, and constraints are
applied to the Horizontal and
the Vertical. These are constraints
to a plane, planar face, etc.
Planes
You can add planes
while in a 3D sketch. 3D plane attributes include:
Define.
Planes can be fully defined, over defined and under defined.
Relations.
You can
Move.
Move planes by dragging, resize planes by dragging the corner handles,
and rotate planes using the center handles.
Activate.
Double-click to activate a plane.
When you use RapidSketch
with any open sketch tool, a plane is created on any planar face that
you select.
Display
In the Properties
PropertyManager, you can hide dimensions, relations or planes.
When sketching in the 2D mode on a 3D plane, entities
that are not on the active sketch plane are muted.
Relations and dimensions that do not involve the
plane or segment on it are hidden.
Sketcher Triad
Use the Sketcher
Triad 
to limit the drag of entities.
To display the sketcher triad:
In a 3D sketch, right-click in the graphics
area and select Show Sketcher Triad.
Aligning the Triad
To align the triad with the component origin:
Select the triad, right-click, and select
Align with component origin.
To align the triad with the component geometry:
Select the triad, right-click, and select Align to...
Select a sketch entity.
You can drag the triad anywhere in the graphics
area. If you drag the triad onto a surface or curve, its axes are oriented
to that geometry.
Modifying Geometry with the Triad
You can drag the triad to modify the geometry in two ways:
-
Select an axis or the plane on the triad, and then drag the geometry
along that axis or in that plane.
Drag the triad onto a point. It locks to that
point, and then you can drag the point by dragging on the axis or plane
of the triad. While the triad is locked, you can still drag other geometry.
