Reorder feature

[CAD-One]

In a part How to reorder features in the browser. I tried to drag and drop it wouldnt work.
Thx.

If you cannot drag a feature up or down within a part, it
generally means that there is feature dependency involved, usually on a feature
located below that selected one. If you can restructure the dependencies, then
yo ushould be able to drag. Can you post the part, zipped?

All you can currently do is sort by part number.
You will need to install the "Bonus Pack" or SDK User Tools "Assembly Tools".
This is located in the directory that you installed IV in: Autodesk\Inventor
200*\SDK\UserTools

Dennis,
Thx for reply. I am talking about assembly features and I cant upload (I am not authorised) this product assembly. Yes there are dependencies. I now understand why they would not reorder by drag and drop.
Thx.

Blair,

I do have the bonus pack installed. When possible, how can I reorder feature.
Where is this tool?

Thx

Think of it this way, a child cannot exist before it's parent.

I don't think it works in an assembly either way. I have always had trouble when trying to reorder holes and other machining. It seems to be much more sensitive maybe it infers dependency where there should be none. And I remember one time I tried to add features by dragging up the EOF marker and couldn't drag it back down. And recently I sent Dennis an assembly where the features puked, maybe it's something I do (I don't recall messing with the order there, but it's a big assembly feature problem that shows how touchy they can be), but I have had very little luck reordering assembly features. It is not as easy as it is in the part environment.

Guys,
I hope autodesk fix this issue. In a large assembly we will not remember the inter depenency between parts while assembling. Even the Imap feature is not useful. The skeleton map it generates about the interdependency is a mess on the screen.
I hope somebody donates some kind of a video clip about the best use of this Imap tool.
Thx

1. iMap maps constraints - does not indicate feature
dependency.

2. Most if not all 3D parametric modelers have feature
dependency. Avoiding dependency requires rethinking your workflow. This is not
something "fixable" in the current sense.

If you create a feature that is based upon an existing feature
(including work features), then that newly created feature cannot be moved above
the dependent feature. See the attached 2009 part.

Assembly features such as a hole are dependent upon a sketch.
That sketch location is dependent upon selection of a face within the assembly.
Therefore, the sketch and the whole are dependent upon that face being present
within the assembly. If that face is deleted or moved, then the sketch, and the
hole feature have no home, forcing redefining of the sketch. It all depends on
what level of the assembly that you're placing the hole feature. If you placed
it at the top level, then it will only exist at the top level.

I've seen one instance myself just yesterday of some bad
parametic processing on Inventor's part. I had modeled a
fairly simple part with the base extrusion going in one
direction. Later in the feature tree I added a linear hole
on one face of the main extrusion (no sketch). Then I thought,
in order to have the origin plane centered on the part's main
extrusion, maybe I should edit the base extrusion to be a
midplane extrusion. Problem is, when I edited that feature,
I got an error message that my holes features had no effect
on the model. So, I tried editing them to see what was up, and
the preview showed the hole placement now going in opposite
directions both ways, and as far as I remember, you are not
allowed to enter "negative" values for these placement
dims, so the easiest fix for me was to undo the midplane feature
edit and live with it the way it was. Inventor SHOULD have been
able to keep those placement dims for the holes without flipping their
directions to make the hole off the part!

I can't tell for sure without seeing the part, but this is probably caused
by the sketch solver. Sketch dimensions don't have a direction (this is one
reason you can't enter a negative number), so it has no idea which side of
the edge it is on. If you move the base feature so the point is now off the
face, the solver just positions it so that it is the correct distance from
the edge.

The assembly solver is variational, so it does have a notion of direction.
You can use negatvie offset values, and it tries to maintain the relative
position of the geometry. The downside is that an assembly constraint can
fail if an update requres the constraint to have the opposite offset value,
while a parametric constraint would be happy.

So linear holes that do NOT use sketches for placement
still use a sketch solver?

This seems like a bug as far as I am concerned!
If the base extrusion is made in the default direction
(first arrow in dialog), then changing it to a midplane
or even the opposite direction works fine and the hole
is updated properly. However, if the base extrusion is
made initially in the opposite direction (middle arrow icon)
and you then try to change the extrusion direction after
placing the hole, BOTH placement directions are flipped.
The attached part is extruded in the opposite direction,
try changing it to a midplane extrusion and the hole will
fail!

I'm interested to see how InventorFusion handles this. I've seen ads from SpaceClaim, that claim not to have dependencies. Fusion is also supposed to allow users to "easily express ... ideas irrespective of feature order, dependencies, or original CAD system"

We'll just have to wait on that one... 🙂
