sketch driven pattern-place holes equi-dist along a closed sketch

sketch driven pattern-place holes equi-dist along a closed sketch

sketch driven pattern-place holes equi-dist along a closed sketch

(OP)
I have a closed sketch, made of 8 segments-4 lines,  and 4 radius'(radius' are tangent to lines)-aka "a rectangle with filleted corners".  I want to use the closed sketch as the centerline of a pattern of holes, where the centers of holes are equally spaced from each other.  I'm not having any luck with sketch driven pattern. It seems to only select 1 of the path segments for the path.  

RE: sketch driven pattern-place holes equi-dist along a closed sketch

Create a "composite curve" from the sketch, then use it for your pattern to follow.  This will group them into one entity.

RE: sketch driven pattern-place holes equi-dist along a closed sketch

(OP)
here's my tree, extrude1-(rect. plate), CompCurve1 (path), Cut-Extrude2 (hole I want to pattern on path).

Then I tried the curve driven pattern.  (see below for parameters.

I get a curvepattern in the list, but no corresponding geometry ( only original hole-cut extrude2)  What secret am I missing?





direct 1=compcurve1
#=5
equal spc is checked
curve method:
trans curve=filled
offset=empty
tangent=filled
slign=empty
feature to pattern=cut-extrude2
faces to pattern=empty

Nothing

RE: sketch driven pattern-place holes equi-dist along a closed sketch

I'm not sure what's wrong.  Your settings work for me.

What SP are you on?  I'm on 3.0

While editing/moving things around, mine went to only one instance once.  But I can not make it happen again.  Try deleting the pattern and re-create it.

2003 sp5,  I tried it again on a different part.  It worked a couple of times-depending on the numbers I put in, weird.

Sounds like a glitch ... submit the problem to you VAR &/or SW.

Everyone has a photographic memory. Some just don't have film.

RE: sketch driven pattern-place holes equi-dist along a closed sketch

For 2003 there is an SP 5.1

It does have a fixed SPR (# 192434) "Curve driven pattern will not consistently generate in SolidWorks 2003 SP5.0. Pattern may generate after several forced rebuilds."

If you have a subscription, download 5.1

RE: sketch driven pattern-place holes equi-dist along a closed sketch

(OP)
that was it, I loaded the sp5.1 and it was instantly fixed.
thanks
