Derived Sketch
Derives a sketch from another sketch that belongs to the same part,
or derives a sketch from another sketch in the same assembly.
When you derive a sketch from an existing sketch, you are assured that
the two sketches will retain the characteristics that they share in common.
Changes that you make to the original sketch are reflected in the derived
sketch.
To derive a sketch from a sketch in the
same part:
Select the sketch from which you want to derive
a new sketch.
Hold the Ctrl
key and click the face on which you want to place the new sketch.
-
Click Insert,
Derived Sketch.
The sketch appears on the plane of the selected face, and the status
line indicates that you are editing the sketch.
Position the derived sketch by dragging and dimensioning
it to the selected face. (The derived sketch is rigid and drags as a whole
entity.)
Exit the
Sketch.
To derive a sketch from a sketch in the
same assembly:
Right-click the part on which you want to place
a derived sketch.
Select Edit Part.
Select the sketch (in the same assembly) from
which you want to derive a new sketch.
Hold the Ctrl
key and click the face on which you want to place the new sketch.
-
Click Insert,
Derived Sketch.
The sketch appears on the plane of the selected face.
Position the derived sketch by dragging and dimensioning
it to the selected face. (The derived sketch is rigid and drags as a whole
entity.)
Exit the
sketch.
Click Edit Component on the
Assembly toolbar.
If you
delete a sketch from which a new sketch was derived, you are prompted
that all derived sketches will automatically be underived. Click Yes or No.
You cannot
add or delete sketch entities in a derived sketch. However, you can re-orient
it with dimensions and geometric relations.
When you
make changes to the original sketch, the derived sketch updates automatically.
To break the link between
the derived sketch and its parent sketch, right-click the derived sketch
in the FeatureManager design tree and select Underive.
(After the link is broken, the derived sketch no longer updates when you
change the original sketch.)
