Curve-driven repetition

2D plans Layout
1

Hello everyone,

I would like to do a curve-driven repetition for chain links but it doesn't work and as you can see on the screen, the origin of the function is a bit in the choices, is there a way or a hack to indicate the start of my curve?

 

Regards

Hello

I think it's the reference point that you should choose "component origin" or "selected point".

See these tutorials for more info:

Hello

Is there no possibility to drag the original arrow with the mouse?

4

Unfortunately even selecting the starting point of my curve nothing helps and no impossible to move the arrow :/

But where is the first component, the one before the repetition?

Perhaps he should be constrained on the starting point.

At the bottom right it is constrained on the same point as the one selected cf image with zoom

By reversing direction 1 (the double blue and black arrow), it doesn't work?

No, nothing helps:/

Edit: In my sketch I am only equal radii and all tangent no break on the curve I don't really understand where the problem can come from :/

I found two bugs very similar to this problem in the SolidWorks database:

The first offers a solution:

SPR #:508101

Problem description:

Feature Driven Component Pattern using part level Curve Driven Pattern as driving feature does not locate components correctly if patterned component is rotated from its original location

Solution:
In some cases, this problem has been found to occur when the component's reference plane, whose driving pattern is being selected for the feature driven component pattern, are not coincident with the assembly's reference planes. Mating these planes to be coincident may workaround the problem.

To try.

Otherwise, the other reported issue has no solution (SPR 683970): 

Problem description :

Feature driven component pattern using part curve driven pattern doesn't position component correctly when part curve driven pattern is inclined.

So to test: put the plans (part and assembly) coincide!

Thanks for the info I tested by putting the plans straight nothing did I even modified my sketch by adding a straight line telling myself that it was maybe the succession of arcs that bothered him but nothing either :/

 

Edit, a little clarification, my sequence of arcs was put as a trajectory in the sketch to be able to control the total length, I don't know if it influences it or not?

Hello

 

See the example attached, he may be able to help you.

It is used to repeat a cleat along a chain path (simplified modeling)

I remember that it must be a curve that drives, which curve is a "converted" sketch with the following options: tool + spline tool + adjust the spline + check "fix"

 Hello BBARRAND,

 

Thank you very much I proceeded as follows

New sketch where I make the entities of my basic sketch which is converted into a trajectory for my needs and then via tool => spline tool => adjust the spline and check "fix"

 

Thank you so much BBARRAND

Hello

Another solution: the sketch must be transformed into a composite curve

(this method is used to represent toothed belts with their teeth)

 

Kind regards
