Creating hole in ellipse shape..

[suganthan.mech]

Hello Buddies

Kindly tell me how to creat holes in ellipse shape. I need to pattern the hole in ellipse shape. Please find the image file. Kindly reply its very urgent..

Could you create a ellipse-shaped extrusion and simply select *remove
material* away the shape?

Firstly, I believe that's an oval, not an ellipse (an ellipse is a
circle stretched in one axis). If you had wanted an ellipse, it might
have made sense to use some equations somehow...

There are several solutions.

The easiest, assuming that the points you show are patterned, would be
to create an axis through the pattern leader of the points, then create
a hole on the axis, then reference pattern the axis and then the hole.
Reference patterns are extremely powerful and very useful.

If the points aren't patterned, you could create the first hole and then
copy and paste it onto each point (again, you may need to create an axis
first).

Or you could ignore the points completely, create a semicircle pattern
of holes and a line pattern of holes, and mirror each of these.

Ingersoll,
1- Sketch the curve
2- Create the hole on an endpoint (See yellow arrow for start point)
3- PATTERN -> CURVE (specify the spacing)

You can create a sketched curve and do a fill pattern on it. I've done it
once, but don't remember the details of the steps involved. I'm sure someone
here can elaborate...

[A.DelNegro]

One other possibility would be to calculate the x,y locations of the
holes and use a pattern table to fix the locations.



I thought Pro/E could pattern along a curve now, as well. Can't say
I've done it, but theoretically you could make a curve in the shape of
the ellipse and then pattern the holes along it.

It can, as of WF3. It's very useful - suppose you want 8 equidistant holes,
centered on a part, but want to be able to have the distance change as the
part length changes, since you're still iterating your design. Sketch a
straight curve, centered on the centerline, create your hole on one end of
the curve, select pattern > curve > select the curve, change the criteria
from distance to number of holes, set the #, voila!

Hole tables are just a tidy way to produce several identical holes at a
range of different positions - you can type in all the coordinates (x
and y, or radius and angle) in one place rather than creating lots of
independent features.

I don't have a lot of experience using top-down design, but when I've
tried to use reference patterns with inherited or published geometry it
seems more difficult. I'm copying back to the list to see if other
people can help.

If whichever method you choose needs you to input an extra dimension,
then it won't update with the parent unless you create some sort of
external relation.

Translating patterns through copy and publish geometries is possible,
just cumbersome.

* First, create the pattern.
* Now add the leader only to a publish geom feature
* Now pattern the publish geom by reference.
* In the target model, create a copy geom and select the leader of
the publish geom pattern
* Now you can reference pattern the copy geom

Now that I think of it, the publish geom may be unnecessary in this
instance. In that case, simply select the pattern leader for your copy
geom. The publish does give you extra flexibility if you decide later
to remove the pattern, I guess.

Anything else you want to copy into this model will have to go through
another copy / publish geom pair.

Doug,

Sometimes I miss CADDS... where all you had to do is specify and orient a
hole with a major width and minor width... once it WAS so simple.

Try pattern on curve. I just tried it using your shape for the curve and
it is very easy!

BTW WF3.0 will also allow a pattern of holes etc. in a helix curve.
Construct the hole to be patterned, use a Dimensional pattern to offset
the holes X and Y then without leaving the pattern command, apply an
Axis pattern. Of course also in WF3.0 you can then pattern the pattern
to get all sorts of funky layouts. (It does get very memory intensive
and ultimately clunky though!)
