Extract iFeature not showing a parameter

Hi everyone, hope you're well.

I'm trying to create a iFeature that will have different variables, but one of the parameters that would change would be the "Small Hole Amount" (Parameters name is "SMA").

The feature is to create a flange detail of different sizes of flanges we work with, and the bigger the "Center Hole" (Parameter name is "CHS") the more Small holes there will be on the sides to clamp it together.

The problem is that all the sizes I want to change do pop up on the Extract iFeature menu, except the SHA parameter.

Can someone explain why this might not be working, or what I'm doing wrong?

The feature I made is made up of jut 1 sketch, the center hole, the small hole and then that small holes are a circular pattern within that same sketch.

(Linked a few pictures on this as well for better understanding)

@christoffel5DETV

You need one small circle and a Feature Pattern, not a sketch pattern.

Do this simple experiment, edit the sketch and change the pattern number.
Finish sketch. Does the geometry change number of holes?

I understand what you mean, I'll make the center hole a extrusion on it's own, then a the small hole extrusion and then pattern it.
I'll come back to you, thank you.

You have to make everything dependent as well.

Post your actual file if you have trouble figuring it out.

I've tried this and I'm struggling.

Now when I place the iFeature it works again, and I can adjust the hole amount, bit now when placing the iFeature it freaks out and I don't understand.

as far as I'm concerned, all the drawings are depended, if I understand that correctly.

The video I used to learn a bit more about the iFeatures is this one:

You will need to Attach the original source file from which you created the iFeature.

Hi Christoffel,

The issue is with the center point in Sketch5 and Sketch6. The point is constrained to the projection of the origin. This is not desirable. When placing the iFeature, such geometric condition isn't enforced. Here are steps to change in the source part.

1) Open Temp Plate for iFeatures.ipt

2) Edit Sketch5 -> Show All Constraints.

3) Delete the project constraint from the point. The sketch point should be free.

4) Make Sketch5 visible.

5) Edit Sketch6 -> Show All Constraints.

6) Delete the project constraint from the point -> Project the center point from Sketch5. Now the sketch point should follow the center point in Sketch5.

7) Extract iFeature.

Many thanks!

Thank Johnson, I fully understand now what needs to be done here.
