As you knowthere is no direct
command for this.
If you reallywant to create a
mirror image of a 3D sketch you can do it in somecases but your
mouse will have to go some extra miles.
In my casethe 3D sketch was made
up of several straight line segments onseveral different planes and
fillet curves joining them.
This is how Idid it.
1. Extend theend of the 3D sketch
line segment which is nearest to the mirrorplane so that it ends up
on the mirror plane with the added linesegment as a perpendicular
to the mirror plane. You may have to adda fillet also. Later on you
will remove these extra segments ifneed be.
2. Draw asmall circle on the
mirror plane with new end point of the 3Dsketch as center to get
ready for the sweep.
3. Insert,Boss, Sweep using this
circle and the 3D sketch.
4. Select theend surface of the
sweep body which lies on the mirror plane.Insert, Pattern, Mirror,
Body to Mirror and Select the newlycreated sweep body. You will see
the joining mirror body beingcreated.
5. Start anew 3D sketch command,
Pick the Line tool and start creating the 3Dline segments from the
far the far end of the new sweep body. Makesure you are snapping to
the center of the sweep as you go alongthe sweep body till you
reach the mirror plane. Create all straightsegments first and then
add proper fillet wherever it was in theoriginal 3D sketch.
6. Get out ofthe 3D sketch
7. Delete thesweep feature from
the feature tree. You are left with the new 3dketch which is the
mirror image of your 3D sketch.
8. You can goback and delete the
extra line segment/fillet on you original 3Dsketch.
Copy and paste then rotate and move to the plane you would like simplest and easiest way to go about it. If you need more instructions I can show you how SolidWorks is kind of fidgety about it.
If often you use a symmetry of a 3D spline that quite explainably desire to add this function to toolbar. Especially as it is easy to program it on vc. I agree with the author in addition of this functional in the button to toolbar
