parameterization number holes on flange

[Paola]

dear newsgroup visitors,
I have the following problem.

I created a circular flange in inventor 2011
having a set of equal diameter holes,
arranged on a circumference (created with extrusion command).

wanting to parameterize the model, I created an excel file
with three simple parameters:
dflangia
dforo
No

I incorporated the file into the model and entered the appropriate "equations" in the parameters table.

when I change dflangia and/or dphorus and degrade the model, I do not match any problem.
instead, when I modify nfori, the update does not increase the number of holes, but only geometry;
see the attached image.

How can I solve the problem?

do not use the series of circles to eatrudere, but creates only one hole processing, better if with the special command for the holes, not with an extinguishment, and then serializes with the circular series processing the single hole.

 

[Ilario]

of course you will have to review the parameters and formulas for updating the new parameters

Hi, Ilario.
I changed the work as you indicated me and it works perfectly.
Thank you so much.
