Controlling hole & thread size with parameters and ilogic

[navbor]

Hello All,

I am parsing a parameter to my inventor model from Excel. I want to control the size of a threaded hole in my model using this parameter. I have managed to successfully change the thread designation of an existing hole, but I can't seem to find where to control the size of the threaded hole. Any advice? Here is a snippet of my ilogic code controlling the thread designation.

Thank you Swordmaster,

This is the thread I looked out when I figured out how to set the thread designation, but it still does not show me how to control the size. Changing the designation, does not seem to physically change the size of the hole in the geometry, it seems this is only a text attribute of some description and the hole dimensions are controlled in another way.

Rob,

with this rule when i change the thread designation the hole diameter also updates. I can attach the part here if you need it

if

h0_bushing_bolt_hole_dia = 0.875 then

Feature.ThreadDesignation("tapped_hole") = "3/4-10 UNC"

elseif h0_bushing_bolt_hole_dia = 1.25 then

Feature.ThreadDesignation("tapped_hole") = "1-8 UNC"

else

MessageBox.Show("update_thread in flange", "h0_tapped_flange" ,MessageBoxButtons.OK)

end if

Please would you send the part, mine does not seem to update.

Thanks

Rob

I see what you mean, I will have to investigate my side a bit more.

Thanks for your comments.
