Patterns using curves - need advice

rude

New member
I am trying to create a pattern using a curve. I am tryingto create a cut on an inside wall of a non-circular surface. I have created a curve along this surface and now want to create an equally spaced cut along this surface. Everytime I work thru the pattern after creating the first cut the pattern seems to stary away from the surfeace. I place the first cut at the start point of the curve.


Thanks in advance

I'm assuming this isnt a flat surface or you wouldnt be having this problem. Is this a projection curve? Try grouping the curve and the cut together when you pattern it.

The curve is in a single plane and I have referenced the curve withthe cut. I was able to successfully pattern a point on the curve, then when I tried a reference pattern of the point to the cut, I recevied a failure notice saying 1) incompatible dimensions, 2) overlapping geometries. Could there be a problem with the curve?
 
ok.. select ur curve.

place 2 datum points on ur curve in the same feature. i use "real" values vs "ratio" just depends which way u like to work it.

make a VSS on ur curve. Drag the start and end points to the 1st and second points.

group the points. + VSS

pattern the points over a value.

make sure that your points dont overlap or 1 go behind the other as you pattern as this will produce errors. If in doubt pattern the points b4 doing the VSS to make sure you have done this correctly.



---------------------------------------------

Best to take it a step further.
if u take a Analysis feature and some equations u can really make this very kool and adaptive.

<DIV>Dear Bro,</DIV>
<DIV>I did what you said but i could not reach the "Pattern" (see attched file).

<DIV>Please guide me how to pattern datum point if you're free (Could you share the file?

<DIV>Thanks in advanced.</DIV>

I actually solved this by just re-creating my curve internally rather than having an external curve.


Thanks for the advices and tips.


rue dog!
 
That is the same exact problem I had. I stoped it simply by creatingthe curve internally in the pattern creation rather than selecting a curve. A bit inconvienet but it worked for me.
 
sorry mate i can only open wf2 files. ur in wf3

might be a bug in wf3 ? maybe ur on a beta versions or something

patterning a point on a curve, any curve really is quiet simple.


make a curve
put a date point on the curve
select the point hit pattern

<DIV>Yeah, I think you're right. There's bug in wf3.</DIV>
<DIV>Thanks a lot</DIV>

I dont think there is a bug in WF3. Your procedure is wrong.


You are right to the extent of creating the curve.


While making datum points, make TWO points instead of ONE.


Say you need a total of 50 points, Your first point will be at a ratio = 0 and the next would be at a ratio = 1/50 = 0.02.


Dimension pattern the points with an increment of 1/25 =.04. (25 = 50/2)


Trust this helps.
 
BY THE WAY I AM STILL ON WF2.


HOWEVER YOU CAN TRY THE ABOVE METHOD, OR WITH A SINGLE POINT WITH DIMENSION PATTERN.


ENSURE THAT WHILE SELECTING THE CURVE, THE WHOLE CURVE IS SELECTED for creating the DATUM POINT.


From the power point file it appears that only a part is selected.
 
Why would we have to place two points? I understand the reason behind it, but why is this not explained (oh wait...PTC). nevermind. Hopefully they will come through with a fix for this such that we don't have to make two points instead of one.


Possibly, could we create it from a certain distance away from a reference?
 
<DIV>Hi SRINIVASANIYER1,</DIV>
<DIV>I've got it, we have to make datum point at RATIO 0.0 with one or two point (up to you). Thank You, Bro.

<DIV>To rude :make datum point with RATIO 0.0 first, after that pattern that point on curve, those points wont run out of curve.
