Is it possible to create a mirror sketch based on an existing sketch?

Greetings:

I would like to create a loft feature which consists of 2 guide
curves. The second curve is symmetrical about the right plane of the
first one. Is there a way, to create the second guide curve without
needing to resketch & redimension from scratch and in such a way that
when the first guide curve changed; the second one followed?

Thanks in advance for your advice and help.

In the second sketch convert the entities of the first sketch mirror them as
desired and then change them all to construction lines.

That is if they are in parallel planes.

If not you will either have to dimension the second sketch and Link all the
dimensions.

Or

you may be able to create a surface body out of the first contour and mirror
that. and convert entities.

Use a derived sketch and then use plane flipping to get the mirror image if
necessary.

 

CS:

I try your solution with 2 scenarios:

1. Convert the entities of the first sketch and the center line.
Mirror it about the center line. Change the Convert edges to
construction but leave the mirror entity as is.

2. Same as above but change all entities to construction.

Both is working. But when I modify one dimension of the 1st sketch to
make it either wider or narrower, the second one doesn't update.

I didn't try the surface body solution yet. So I don't know if this
will work as I expedted.

P.:

After reading SW help file about Derived sketch, I think this could be
my solution since the derived sketch will update if the first sketch
is mofified. On the model tree, 1st select the Sketch, hit Ctrl +
select the right plane, insert, derived sketch); however, the only
option I have after creating the derived sketh are Move/copy,
Rotate/Copy, and Scale/Copy. Please advise how I can flip the plane.

 

Funny it worked here on 2004 sp4.2

The construction entities have an on edge relationship and should update to
the new sketch upon rebuild and the mirrored entities are a direct mirror
of the converted entities. Maybe you shouldmake sure your mirror
relationships are still there. Maybe tomorrow I will send you an example.

Corey:

I am taking the liberty to send you mine and hope that you don't mind.
It's a bottle.prt

If you try to change any dimension (I change the top dimension 15mm to
10mm in my case) on sketch4, you will notice that sketch5 doesn't
update while I still have the symmetric relationship. If I change

If it doesn't take too much of your time, could you please take a look
and let me know what I am missing?

Thanks in advance for your time and help

 

Sorry, the e-mail bounce back.

I will wait for your response.

 

Remove eroneous leave the "c" and the cap "S"

 

Actually, you have to remove "erooneous" (note the misspelling of the word
erroneous)

I don't keep it the same in my "Let you know what to remove note" and it is
misspelled to make sure that if a harvester program is going to harvest the
address it will have to be ingenious to catch it. If I were writing a
harvesting program I would search for the word remove and try to figure out
what to remove by the following text. So just incase I am not the only one
to think that way I am guarding against the slight chance that they thought
of it. "Conspiracy theorists UNITE" LOL

Hmmmm, I like it. A man with a devious enough thought process to thwart
those that have similar devious thoughts, but are bent on harm. Good job.

Corey:

That's really clever way to thwart off these rodents, pests spammers.

Anyway, the file is on its way and looking forward to seeing what I am missing.

Many thanks.
