Editing Linear Sketch pattern ?

Once a linear sketch pattern is created, added to a feature, and
closed, can that sketch be re-opened and have the linear pattern edited?

 

Yes, edit the sketch, click on one of the patterned items and then
right click on the patterned constraint in the line properties box and
choose edit pattern.

To cool!
Knew there must be a way, but I couldn't figure it out and I hadn't
stumbled across that!

You can also access the "edit linear pattern" option within the pull
down menu which appears with a RMB (right mouse button) click on any
one of the patterned entities in a sketch opened for editing.

No matter how you get there, the only drawback is that the dialog box
for pattern editing has the spacing dimension greyed out. To get around
this, all you have to do is to manually add a dimension between any of
the patterned instances.

Once such a dimension exists, the pattern spacing can be changed even
when the sketch isn't open. Just double click on the sketch name in the
Feature Manager tree, change the dimension and rebuild via the
stoplight icon...

A cool thing about this is that if you don't have a dimension on it, you
can drag a point of the sketch, and the direction and spacing moves
dynamically. You could probably also set it up so that other changes in
the model make the spacing/direction update parametrically.

Sorry if you all knew this already. I've been pretty biased against the
sketch patterns because they used to be pretty bad (solved so slowly,
weren't editable, funky interface, silly name - step and repeat), so I
never discovered this functionality until now.

I think this was shown in one of the training manuals circa SW2003.

 

Matt,

Thanks for the tip about dragging. For it to work, there must be
relations and/or dimensions to fix the position of the patterned (base)
entity. Otherwise the entire pattern gets dragged with no change in
spacing...

BTW, there is a dialog box option for "add dimension" which can be used
when the sketch pattern is first defined.

I think it's a shame that existing patterned sketch entities are not
obvious as such to the user (unless the little relations icons are
displayed), so handling them correctly when editing an old sketch can
be awkward - even to the original author.

Having a color for patterned instances different from the default
sketch entity could be helpful!
