Help with Sweep, Please!!

Hello All,

Although most of the sweep that you see
(http://home.comcast.net/~muggs828/solidworks/Sweep-1.zip) is absorbed by
other features later I'm having trouble adjusting dimensions in this sweep
and continuing to be able to successfully create my variable fillets and
other features later on in this project.
So... My question is; Can someone (much wiser than I) help me with how to
make this sweep behave?
More guide curves, I've tried, but again, maybe someone wiser could do it.
Or maybe there's a better way, but lofting doesn't seem to be the answer
either.

TIA,
Muggs

 

I'm surprised that works. What shape are you trying to get? From the looks
of it, I would guess that you might want to use a surfaces approach,
because you can't make all the faces at the same time.

Aside from that, you may try to use "keep normal constant" or use a
straight line for the path. Could be a lot of answers to your question.

I would assume that the fillet fails because the arc becomes too big? (a
questioning statement isn't that nice)

What kind of chages are being made to the sweep?

Matt & Corey Thanks,
Sorry I can't be more forthcoming, Proprietary crap and all that, but a
front and side view of what actually precedes this sweep are found at:
http://home.comcast.net/~muggs828/solidworks/Sweep-pix.zip

Matt - Using a straight line helps a lot, but then I get a flat at the end
of the sweep.

Corey - Adjusting the preceding feature (lengthening or shortening) screws
the fillet.

Thanks,
Muggs

 

Muggs,

I sent a new version of your file back to your posting address. I assume it
isn't munged up since it hasn't bounced back to me yet. Here is the text of
the message

"How is this. What I did is the strait line method and used a loft to fill
in the flat at the end. I used an arc instead of continuing the spline for
the bottom profile. I don't know if this will eliminate your problem but it
looks like a much less complex of a shape to work with.

Thanks Corey,
I would love to see how you went about it.

You need to replace home with comcast to send email back to me, sorry.

Thanks again,
Muggs

 

To get a better understanding of what is happening...

*) Edit definition of sweep
*) Under the Guide Curves area, click on the 'eyglasses' buttton
*) Press the up/down arrows to scroll through all of the profiles
SolidWorks has created "behind the scenes"
*) Notice how each profile is created releative to the sweep path

See how the profiles turn in relation to the curves of the path?
Having a straight line for your path will keep that from happening
or of course you can use the 'Keep normal constant".
