Parameters Issue

I have a part that is 100mm and I want it to have a hole in the middle. But
when the part is less than 75mm I don't want the hole to show. Does anybody
now how to do this?

You might try throwing a decision into the parameter that locates the
hole in the part. When the part is less than 75 mm, shoot the hole off
the end of the part.

It will be there in the browser, but not in the model.

When I do that I get an error building hole.

Ewwww. I would expect a "the feature didn't change the volume" error.

Just a cautionary note.

The iPart mechanism is the only way to currently suppress features from
a "table".

This sounds like a manual operation. I was hoping for something that would
be automatic as I change the width of the part, all parametric mind you.

shouldn't this be possible? I'm just new to Inventor but I thought this
should be possible, right? Can't you use some sort of formula or
tolerance-setting to do this?

An extruded feature will give you the "didn't
change number of faces" error, but it's still ugly.

Even uglier, (note haven't tried this so it may not work) you could probably make the
part longer than you need, add a hole in the excess area and array it, then extrude cut
off the original hole and the excess part. In the array qty you should be able to have a
parameter set up to reduce the qty in the array if the part gets short enough.

If this is too whacked, then my excuse is I haven't had my coffee yet. 8^)

See the ICF for a solution. Maybe this concept can be adapted to your

The only problem with that Kent is that the hole will still be there with a
74" part. Here's my thought. If the part never has to be less than 25"
then do what Kent said except add a feature with a crossection identical to
the pipe extruded from the cut end 25 inches plus enough to cover the hole.
When the pipe is cut shorter than 75" the hole will be filled back in. Of
course if you cut the pipe too short the second extrusion will break out of
the other end.

One possible method is to leave the hole in the center

of the bar _but_ change the diameter to be ~zero.

Visually you won't see the hole in either the

ipt, iam, or idw files and it doesn't change the

mass properties significantly.



I know it isn't the ideal solution, but it would

allow you to parametrically change the component to

give you what you want. For simple parts it might

be easier to just manually adjust them each time,

however as parts become more complicated this method

has some advantages -- though the ideal solution

would be to control the suppression of features from

a excel spreadsheet that contains the parametric

values.

That's similar (but different) to the solution I posted ICF (title
Parameters Issue).
There's ways (parametrically) to keep it from adding additional material.
Anyway... here it is, and although the fill in doesn't add material in the
100mm & 75mm versions, it still doesn't have errors.

If we had access to the rest of the API from within VBA function called from
parameters this would be so easy...

Hello Brad-

What you are trying to do is what is termed by other CAD systems as creating a "configuration" of the part. My company has been asking Autodesk to include configurations in Inventor since revision 5 and they still don't exist in Inventor. Perhaps if more of you requested configurations they might be included in the product faster. Your best bet is to create an iPart. - that way you can have different sizes of the part in a spreadsheet and include or not include the hole as you choose.

I've posted a solution under yours. It's probably the same solution, I
should have checked first.

The bottom line is, it can be done.

People often refer to the Inventor.customer-files newsgroup as ICF or
