solidworks >> Flat Sheet metal part from 3d cone

by Tweasl » Wed, 09 May 2007 22:51:54 GMT

Hello all,

I am new to Solid Works and have been pulling my hair out on how to
convert a 3d cone into a flattened sheet metal part. The cone has been
created properly using a thin loftwith two sketches. It needs to be cut
and then flattened. Any help would be appreciated.

Thanks Larry

Try making your cone "properly" with a revolve, instead.

did that work? bob z. gets VERY inconsistent behavior from solidworks
when trying to flatten a sheet metal cone. bob z. spent hours trying
to figure out what he was doing wrong and what worked on one cone
didn't work on the very next cone.

Look at Ed Eaton's SWW2007 presentation. I think he touched on that
subject.

Larry,

In the two sketches did you draw circle's or arc's?

Did you use "Sheet Metal" "Lofted Bend" or "Features" "Lofted
Base/Boss"?

******
If you used two circles I suggest you edit your sketches.
Make them arc's,
1) Arc properties
a) start points will be
i) vertical
ii) X.0
iii) Y=(arc radius)
c) angle use "359.99" deg.

Then use "Sheet Metal" "Lofted Bend", then to flatten out the pattern
you can "unsupress" "unfold" or "Flatten-Pattern" which ever it is
(don't remember the exact term SolidWorks uses off the top of my
head.)

If you need a specific gap between ends (your referenced cut) you have
a little more work to do.

Made the cone "properly" with a revolve. Easy enough thanks. Still cant
make a pattern from this, any ideas?

Your cone must have a gap. Use the EDGE if the gap for the "Fixed face
or edge........works fine, just tried it.........

Nice Cone tips and tricks. Can't wait to try a couple out and see
which works best. Maybe an old dog can learn a new trick or two.

Thanks guys,
Tom

It may also work if you use a lofted bend feature from the Sheetmetal
Tool Bar. Also, leave a small gap in the side of the cone so that it
appears to be made from sheetmetal.

yes, this is the part that bob z. has found to be very inconsistent -
determining which edge for the "fixed". what works today, doesn't
always work tomorrow. of course, bob z. has an exclusive relation
with Murphy's Law.

1. Flat pattern of a mirrored sheet metal part

Flat pattern of a mirrored sheet metal part-

I noticed this as a request for enhancement, here is a tip to get your
flat pattern, before you mirror the part, just create a drawing and
drop your sheet metal part into it, using the Flat Pattern, close the
drawing, no need to save. All that did for us was create the flat
pattern config. Now mirror the part and the flat pattern config. comes
with it. Including any changes.

3. Sheet metal blank development - elliptical cone

Hi,

We manufacture vessels fabricated from flat steel sheet, designed
using AutoCad LT98. We want to have the ability to produce blank
developments automatically from the CAD, specifically the blank
development of elliptical cone frustum shapes (circle at top of cone,
ellipse at base).

I know that there are LISP routines which can do blank developments,
but LT98 can't do LISP and even upgrading to LT2005 isn't going to
help on that score. I know that solid modelling packages like Inventor
and Solidworks can do it, but that's a huge investment for such a
simple problem.

So.. do you guys know of any other way that this can be done
automatically on cad, or any lightweight programs or utilities which I
should be looking at?

Thanks in advance for any help you may be able to offer.

4. Raised features on sheet metal flat pattern?

5. Sheet Metal Flat Pattern Origin Question

Hi,

I created a sheetmetal part with everything referenced and mirror to the 
Origin.

Why is it when I flatten the part, does SW (2006, sp4.1) move the part from 
the origin???

How do I get the origin to be in the center of the Flat Pattern (it is 
centered nicely on the flat with two symmetric tabs) to be back in the 
center??? This is very confusing... the part is not that complicated and 
unfolds perfectly.

I would like it to be centered so that I can use autodimension to dim the 
part with ordinates to save some time - guess I am out of luck already - I 
have spent too much time already...

What am I doing wrong?  About to loose it...

7. Sheet metal flat length dimension for BOM property

One of the guys here (Tom Stock) finally figured out a good way to put a 
flat length reference dimension in a sheet metal part and have it stay 
accurate, without the hassle of adding a line that is equation driven.

1.  In a sheet metal part, put in an unfold feature.
2.  Then start a sketch on one of the faces.
3.  In that sketch, insert a point at one of the corners, or put a 
construction line at one end, or something - you have to have a sketch 
entity.
4.  Put a dimension from that entity to the other end of the part.
5.  Exit the sketch.
6.  Put in a fold feature.

Now, when you fill in the config specific properties, you can pick that 
dimension for your length property, and it will update properly in the SW 
BOM.
