Hello,

 

How do i calculate the distance for using Circular PAttern so that Extrusion-3 finishes at the end of the Arc (Extrusion-2). I used 11 occurences as shown by Circular Pattern feature bit it does not line up.

 

Is there an alternative way to achieve this which is simpler ?

 

regards,

Add a driven dimension parameter to your Arc and then reference it in your calculation.

Is this a school problem - it seems like it come up here about this time every year?

 

Looks like an error on logic to me, isn't the angle around the arc center point as axis really 360-70.753897274=

 

See attached file.

 

Have you installed all Service Packs and Updates for 2015?

 

Just for fun - turn in the curve driven pattern solution to your instructor.

I used the Driven Pattern for Rectangle Pattern 3 and it worked. When i tried the same for Rectangle Pattern 4 i cannot get the pattern to work correctly. I used 11 to get the pattern distributed equally except there is 1 extra group. When i use 10 then it does not line up. What i have i done wrong?

Use some logic.

Think about the function of the part.

What is the purpose of the divisions?

 

Back in a while with logical solution.

Examine this "solution".

 

Drag the red End of Part marker up and down the feature tree to see the logic that I used.
