Symmetry relationship

N/A

Hi there!
I am new to Solid Edge 2D (which I am very glad to find for free, thanks!).
I am trying to design a guitar body. As a starting point I want the body to be symmetrical
(left/right), so I first draw an center line.
Then I draw a shape on the left side of the center line. This shape is made of connected
curves (spline-like) and straight line segments.
In order to get the symmetrical part I do the following : select the whole left
shape and duplicate it by copy and paste. Then I move the copy to the right of the
center line. Finally I have to apply the symmetric relationship to each component
of the shape (for each curve, for each line segment etc...).
1- This works fine, but is there a faster way to do so and/or apply the symmetry
directly to the entire shape (all curves and lines...) ? (or to avoid the copy/paste
step?)
2- Also if once I did what is described above I want to add a point to a spline-like
curve, it does it on the selected curve only, and this change is not reported on
the symmetric curve. Is there a way to do so?

Thank you!
Cedric

Use the Mirror command instead of Copy. It is located on your left tool bar
in a fly out button that includes Move, Rotate, Mirror, Scale & Stretch.
Make sure you have Tools-Maintain Relationships checked before mirroring
your geometry. You can also turn on/off Tools-Relationship handles to see
the symetric relationship inidicator on your geometry.
After testing, it appears that when you add a point to a curve you will then
need to remirror that curve.

Oh great!
Thanks David. I'll try that tonight.

Cedric,
Here is something you can try that will help you keep the symmetric shape of
the guitar body. I attached an image for reference.
1. Make sure you have Maintain relationships and Relationship Handles turned
on under the Tools menu at the top of the application window.
2. Draw the shape of half the guitar. Put the centerline on a separate layer
so you can turn off the display of it. You do not see the centerline. It is
on Layer1 and Layer1 is turned off.
3. Over to the left of the application window is EdgeBar. Edge Bar has tabs
at the top for Layer, Library, Group, etc. You can click on the Layers tab
to create, activate and show hide Layers.
4. Now use the block command to create a block using the geometry. The block
command is at the bottom of the draw toolbar. When you create the block, it
will place an occurrence of the block in the original location.
5. Click on the Library tab in EdgeBar. Click on the show blocks button
under the library tab. This will display the blocks that exist in the file.
Look toward the bottom left you will see 'Active Document' and the block you
created.
6. Click on and drag the block into the display window. Drop the block. The
new block will be in the same orientation as the original block.
7. Mirror the block around the horizontal centerline. The mirror command is
on the flyout of the Move command. Make sure the Copy button on the Mirror
ribbon bar is poped up. You do not want to mirror copy.
8. Now you have the two halves displayed. You need to connect them.
9. Right mouse button click in the gray area to the right of the Main
toolbar at the top of the application window. Click on relationships to turn
on the relationships ribbon bar.
10. Click on the Connect command. It is the first command on the
relationships tool bar. Connect the upper end of the lines in the bottom
half block to the lower ends of the lines in the upper half block.
11. If you need to make an edit to the shape. Double click on either block
and you will see the block geometry. Make your change and then click on the
Return button. The same change will be made to both blocks.
Regards,
Rick B.

Thanks Ricky!
That seems a more advanced, sophisticated solution. I've printed your suggestion
and I'll try it tonight.
Thank you very much for the detailed explanation + the very pertinent illustration
Smiley Happy !
Cheers.

Re: Symmetry relationship

Hi David and Ricky.
I shortly tried your suggestions yesterday night.
David, the Mirror command is what i was looking for to speed up the process conveniently.
Ricky, even though your suggestion made me learn about layers and blocks, it is
not really what I was looking for, as when editing a block's geometry I cannot see
the effect on the whole drawing (I see only one side of the guitar, i.e. only one
block), or can I?
It is important for me to see the immediate effect on the symmetric part as I am
editing the geometry, otherwise i do not really get the sense of the chnage I am
making.

Anyway now I think I'm ready to go further.
Thank you both!
Regards
Cedric

Cedric,
I'm glad you found a solution to your problem.
You are correct. Currently when you edit a block, all you see is the block
geometry. In place editing of blocks is on the list for future enhancements.
What do you think of the software up to this point?

Hi Ricky.
Oh I see that you are fine-tuning next versions to my needs! Smiley Wink Great! Smiley Happy
Up to this point the software is what I was looking for. It seems powerful to me
and much better than any other free tool I have tried up to now.
I just need to get acquainted to the basics. I would have liked to follow more tutorials
on drawings (I only found one, right?).
I really like the geometric relationships. And the GUI is fairly simple with respect
to the number of tools it provides.
So that's all positive!
Thank you!
(see you soon for a new question Smiley Happy ... )
Cheers
Cedric
