what I would really like

[dakeb]

To be able to create a cut feature comprising a number of holes and later
convert it to a pattern table.

I've done something similar by patterning a point or axis (don't remember which),
reference patterning a cut, then turning this into a pattern table and eliminating
some of the elements. Now, it's possible to do somewhat the same thing with a fill
pattern and selectively delete pattern elements.

It's deleting the unwanted elements that's the problem. In rel 2001 you
can't do it graphically, you have to do it in a text file and that is a
major headache. If I could just select the instances I don't want in the
model and delete them that'd be okay. Can you do this in WF?

Why can't PTC make a pattern table from a cut? All the dimensions exist in
the cut, it would simply have to convert them to the table format.

WF lets you select elements of a fill pattern graphically for suppression. It also
lets you switch between different types of patterns (linear, table, fill) from a
drop down list. The tough thing with a table is, as you pointed out, managing
anything. It's pretty difficult to change the pattern spacing in either or both
directions. With WF, you can switch to linear pattern to change the spacing then
switch back to table to remove instances.

I can't see why you wouldn't be able to except that if it's a collection of
features, you may have to group them first. Seems to me that anything you can
pattern, you should be able to make 'to table'. Graphical control comes with fill
patterns because you get a preview of instance positions where you can delete
some; not sure about tables in WF, though I'm pretty sure that by WF2 this gets
graphical, too.

The thing is, I want to make a pattern of something that isn't a logical
pattern. Like a 'random' array of round cuts, with no linear spacing in any
direction. So in rel 2001 I have to do it as a cut feature, with the
'random' array of round cuts drawn in sketcher. The reason I want to make it
into a pattern is so I can use the round cuts as pilot holes, and then place
a tapped hole feature on the first one and ref. pattern the rest of them.

This is new stuff to me, can't claim to know anything about it; but that's
never stopped me before so.... <g>

Without an available function and just off the top of my head (well, after
a little 'thought', fwiw) I think I'd consider table patterning datum
points for the pilot holes, assuming they are all located from a common
reference, instead of going the multiple holes with a cut route. I don't
think WF offers any help for adding or deleting pattern instances
graphically, but you can RMB / Edit the locating dimensions graphically
(WF2 only?). It's not especially quick, the entire part has to be regen'd
to effect changes, but it's more intuitive than working with the table (?).
