Offset Entities
Offset one or more sketch entities, selected model edges, or model faces
by a specified distance. For example, you can offset sketch entities such
as splines or arcs, sets of model edges, loops, and so on.
You can offset
finite lines, arcs, and splines. You cannot offset fit splines, previously
offset splines, or entities that would result in self-intersecting geometry.
If the original entity changes,
then the offset entity also changes when you rebuild the model.
To create a sketch offset:
In an open
sketch, select one or more sketch entities, a model face, or a model edge.
Click Offset Entities (Sketch
toolbar) or Tools, Sketch
Tools, Offset Entities.
In the PropertyManager, under Parameters,
set the following:
When you click in the graphics area, the Offset
Entity is complete. Set the Parameters
before
you click in the graphics area.
Offset
Distance . Set a value
to offset the sketch entity by a specified distance. To see a dynamic
preview, hold down the mouse button and drag the pointer in the graphics
area. When you release the mouse button, the Offset Entity is complete.
Add
dimensions. Include the Offset
Distance in the sketch.
This does not affect any dimensions included with the original sketch
entity.
Reverse.
Change the direction of a one-directional offset.
Select
chain. Create an offset of all contiguous sketch entities.
Bi-directional.
Create offset entities in two directions.
Make
base construction. Convert the original sketch entity to a construction
line.
Cap
ends. Extend the original non-intersecting sketch entities by selecting
Bi-directional, and adding a cap.
You can create Arcs or Lines
as extension cap types.
Click or click in the graphics area.
An Offset
Entities relation is created between the new sketch
entity and the selected entity. If the original entity changes, the new
entity updates to maintain the offset.
If you
are creating a component or feature in the context of an
assembly and Do
not create references external to the model is selected in Tools, Options,
External
References, then the
sketch relations described above are not
created. See Controlling
Creation of External References.
To change the size of a sketch
offset:
Double-click
the offset’s dimension and change the value. In a bi-directional offset,
change the dimensions of the two offsets individually.
